Dead pixels on my topaz phones screen - Touch Diamond2, Pure Q&A, Help & Troubleshooting

please help!!
i have observed some dead pixels on my phone but i dont know how to get rid off them. there is small circle in the middle of the screen and also on its side. i am not sure what is the best way of dealing with this issue??
please forward any suggestion to my email address.
thanks very much

You are experiencing "Newton Rings" where your digitizer has partially collapsed. You can attempt to use duct tape and pull the outter layer away and see if it goes away. Otherwise a screen replacement is the fix.
Search on "Newton Rings" for more info, also there are screen replacement directions in the forums somewhere.

Can you post a picture of your problem? Dead pixel sounds like a LCD-screen problem. Those rings (Bruce Inman calld them "Newton Rings") are a digitizer (the touching unit) problem.

how o do the trick witht the tape
how to do the trick with the duct tape??

I have the same problem. It's a LCD or tablet problem?

same here... Is there a way to change digitizer only, without breaking the phone in 200 pieces?

let me tell you guys, frankly I was also victim of that kind of spots on my screen, and those came on screen when I was supposed to sale my mobile, I obsessed then I found a solution from this site, to keep my mobile into freezer area of any fridge packing into plastic bag or shoping bag but close it carefully.
Sounds might seem funny or joke but those who really experienced with freezing technique know It really help.... keep your mobile into freezing area about 10 hours or more.... then see the result

Screen broken?

Hi,
yesterday i dropped my kaiser and since then the screen shows everything with a yellowish colour. Also there is a thin white line on the left side of the screen.
These things( line and yellowish colour ) are there ALL THE TIME , even when the phone boots and so on.
I already tried soft- and hardreset and i reflashed the device, no change.
Im guessing its a hardware defect,
has anyone else ever experienced something like that?
What can I do?

wow nice help man you should work in customer support !!
There are a number of threads about people with cracked/broken screens, or screens not visibly broken but not working. Lots of these suggest checking that the internal ribbon cable is correctly seated - which may have become dislodged when you dropped your phone.
Have a look at Mike Channons dismantling guide - it may help.

Let's see... you have a broken screen.... SO REPLACE IT!

Moving couch = Broken Tilt

I'm assuming I smashed my At&t tilt or something, there is no cracks on the screen or anything, but the pic below shows the display I get. I'll have the phone for about a year in about 2 weeks. Anyone have an idea as to how much At&t or HTC will charge to fix this or am I better off buying a new phone? Or any ideas as to what could be broken and how it can be fixed? It doesn't allow me to do a hard reset. Thanks
well i don't know if warranty will cover it or not but you are still under your one year warranty so you could try to get a replacement. Its hard to say what could be causing it. You can check out mike channon's articles on disassembling a kaiser.
Good luck.

Well to my trained eye, it looks as though you have actually cracked the lcd screen. This damage isnt generally covered by any manufacturers standard warranty. Unless you purchased an extra warranty including accidental damage, I think its up to you to repair yourself unless you want to spend 400USD + for the repair. Taking it apart isnt terribly difficult and I have seen links to lcd screens posted all over for no more than 100USD. Check Ebay also.

I don't see a crack in the screen. Can there still be a crack in it that isn't visible or not noticeable until you take it apart? If that's the case I'll either buy a new screen or just buy a new phone on ebay for 200bux. Also anyone have any recommended sites on how to replace the screen?
This raises a great question for me. i work in a clean room/static sensative environment and repair and calibrate many different types of electronics (mostly signal generators & spectrum analyzers). I was wondering if anyone here has actually attempted to replace a LCD screen with success. And if so, how complicated the process was. I have downloaded the schematical drawings and have found replacement parts for the kaiser online for extremely cheap. i will post the site as soon as i find it again.
I did a screen replacement on a Wizard, and it wasn't that difficult. just make sure you don't break anything while trying to pry small pieces off to get to the screen.

Generally you will NOT see a physical crack on the surface. The surface is actually JUST a digitizer ( a separate piece which is built into or ontop of your LCD for input purposes ). The digitizer is basically your touch screen portion of the LCD. What is actually cracked is the thin film below that which contains all of the liquid crystals.
As far as the replacement goes, I believe it is Michael Channon who has the step by step instructions on how to disassemble and replace the LCD. It isnt a hard task from what I can tell. I had taken my hermes ( Tytan ) apart so many times that i could do it in my sleep. Its not a terribly difficult process.
Here is Michaels Guide
Its not in English but its not hard to follow the pictures. He has done a great job at documenting the procedure.
If you are a bit scared to try it yourself, have a geeky friend do it for you ( maybe get him a date to a movie or something lol )
It should only cost you no more than 50$USD to repair ( Minus the bribe for a date lol )
Hope this helps you out !

Thx, I'm gonna give it a shot. I went ahead and bought the screen off ebay from the post by pyraxiate. Worst case I mess it up and buy a new phone of ebay for 150-200, which is what I originally thought I'd have to do, so this at least gives me a chance to save some $$$

Glad I could help
Got it all done, actually my pops did it. Works great, he took it apart just like the Mike Channon pics show, don't know if you had to do all of it or not just to replace the screen, but he did. Only one little annoying thing now that it's back together is that a small part of the black plastic out case hangs out just a tab and isn't flush, which makes it a little annoying when hitting the power/standby button on the right side of the phone. But I can learn to live with that I think. thanks for all the help.
congratulations!
good to hear you've achieved a successful repair!
correct me if i'm wrong...are you saying that the two halves of the phone (screen and keyboard) don't align properly when the keyboard is closed? if so, i remember a thread in this section of the kaiser forums that details (with pictures) how to possibly fix that particular problem!!!
"search and ye shall foundeth it !!!"

As was stated before, there is a thread for the case not aligning. I did some quick looking but to no avail. If i come across it ill be sure to post it
I'm not sure if I'm explaining it correctly. But it's basically the outer case, and around the power button it's not flush. Not sure if you can tell from my pics. I tried also doing a search w/no luck. I'm sure there is some specific name or something other than case that it's under.
When i replaced my faceplate i had the same problem. all i did was push it in...kinda hard, and it poped in, or you could use a plasic flathead and pop it back in...

I tried that, and it doesn't seem to pop in at all.
I think its just like DemoShadow said. I dropped mine once and it seems to be a similar issue. I also just pushed really hard to get it to pop back in. I think its just that clip isnt in place as it should be when it was put back together. If anything, try to take it apart and put it back together

how did you put the keyboard back on????????????????
Can you be more specific?
Hey,
I literally just replaced the screen on my backup Tilt last night. Still got most of it in my head.
What, exactly, do you mean about putting the keyboard back on? Got any pics of where you are now?
This was one of the easiest things I've had to do...asside from it being somewhat tedious. Most of my issues were resolved by MAGNIFICATION! Once I could see what I was doing, there were almost no issues.
I only paid $31.99 on eBay for a screen with free shipping (from USA no less)...less than the $35 I would have had to pay with the insurance through my Provider Dealer...and I didn't have to wait for 3-5 weeks to get it back.
I'd do this for people with broken screens as a service, but I can't guarantee the cost of the screen...it goes up and down too much.
If you can be real descriptive, or have pictures, I'm pretty sure I can help get you back together.
Let me know, I'll keep an eye on this thread...

here's some dismantling guides

you dont have to remove the keyboard to replace the LCD, unless u're talking about the outer keypad, which just sits in its spot

touch screen unresponsive

My touch screen has stopped working in Android. I can navigate with d button but can't use the screen. I've tried re-installing with the lastest nbh and the latest version of warm donut. but still the screen wont' register a touch. occassionally it does if the google search widget is installed. I might flash a windows rom to see if it's a hardware problem. Anyone have any other ideas?
Thanks!

Try going back to WM and see if it works.
indeed it is hardware
same problem with WM. guess it's time for a new phone. thanks for the responses.
Jumbo, you can still salvage the phone.... try this... take a duct tape and stick one end on the screen and gently lift the other end gently... enough relieve some pressure off the screen ( the digitizer)... keep a contant pressure OFF the screen for about 2-3 mins....
Then try the screen again... see if there is any response...
If that does not work
Get a exacto knife... and gently slide the exacto under the digitizer ( the plastic screen ) its about 1 mm thick... do this from the top and once you are able to grip the top, slowly lift this screen... about half and inch to an inch max from the top while keeping the bottom of the screen stuck because it has a connection you dont want to cut or disconnect otherwise you will have to open the HTC completely... take a clean soft cloth and swipe the inner screen ( dont put too much pressure on the lcd which is the glass screen fixed on the htc ... the digitizer however , which is the plastic screen you lifted off can be cleaned from the inside.
I had an unresponsive one as well and this is what i did and i revived my htc.... otherwise you can buy another digitizer off ebay with the tool but it looks complicated to open...
good luck...
a little disclaimer : dont hold me responsible if you screw up... this worked on mine and i was able to stick back the digitizer in its original place...i used alcohol to clean the inside, because my digitzer was always touching the lcd and it had an oily patch where it touch... must have been sweat or something and because i put it in my back pocket i must have had too much pressure on the screen
Sweet! There's hope! I'd love to have this little phone back and have it take me to the promised land of the HTC EVO. I'll try this out.
It lives!
Turns out taking off the screen protector and simply pulling up a bit on the corner of the lcd screen fixed it. Thanks, QkSi1ver!

if your inner LCD ( the glass one) is not cracked like a glass and you can see the full LCD and that the only symptom is that you cant navigate using the screen, then its just because the digitizer is touching the LCD and screwing up the I/O...
The 2 easy fix is relatively safe and not much is required (Some old Duck Tape & Alcohol).. .than having to buy another digitizer and put it apart... something which i was not comfortable with even if i have the tool .
But as with any tinkering, be careful when you lift it up or put the exacto ( this when i tried it on mine i remember i was crossing my fingers (with my other hand of course ) so that i dont cut anything like wires or contacts underneath because i had no idea what i was getting into... but after doing it i can safely say, you can't screw it up as long as you dont use the exacto at the bottom end of the touch )
You only need the knife to lift it up a little and enough for you to grab it and life the top part up so that you can fit a cotton cloth underneadth to clean the inner side of the LCD and digitzer...
Funny,
I had the same problem after installing Android. Would up returning/swapping my Vogue.
I wonder if Android usage affects this in any way--even indirectly, e.g. Vogues weren't designed to take constant/large/sweeping finger presses, etc.
Any thoughts?

I would like to add that I had to replace my digitizer a few months back and it was actually quite easy to do and the digitizer itself was cheap ($10 on ebay).
Sadly, you are exactly right. No more back pocket, evar! Thanks again, so happy to have a live cell phone again...

You sure? Is it unfixable?
EDIT: I put some duct tape on the screen cover and lifted it up and the oily rectangle went away but comes right back. I'll have to do some cleaning of the screen. Perhaps it is warped but removing the oily substance will help hopefully.

Scratched screen

I have some kind of bad scratches on my screen, I was just wondering if I choose to replace it will I need to swap the digitizer, screen or front case?
Its not causing many problems yet, but in the sun they show up really bad and make things under the scratches kind of hard to see.

The Actual front of the screen is actually the digitizer so thats what you would have to replace, the font case dosent have a clear part its the digitizer
and believe it or not thats probably the cheapest part of all 3 to replace

Check if there's any protection cover on the screen. In case there's no cover and you see the touchscreen was damaged, try to replace it. Someone already have posted youtube link to tutorial. For instance, you can buy a new touchscreen on ebay (i can't post the link)

[How-To] Disassemble your L90 (D415 based)

For reference only! This will absolutely VOID any warranty you may have on your device. If you believe you have a VALID reason to take apart a fully functioning phone, you DON'T! You are responsible for your actions and the reuslt of your actions, don't lay fault with anyone else.
The phone used to create the guide is my first D415. It took a long walk of a short box and shattered the screen. Let's leave it at that, please. And you thought I was going to take apart a fully functioning phone, didn't you?
You shall acquire and assemble in the same place, these items
The phone you wish to disassemble
A "precision" philips head screwdriver (don't know what a philips head is? Please go elsewhere)
A thin piece of plastic, an ID or bank card, guitar pick, even the edge of a plastic knife (file off the "teeth") You get the idea....
Optional items
Small blunt tip tweezers
Container to hold screws and such
Magnet to find the screws you drop (you will drop at least one)
Magnifying glass
Pictures say more with less words, so.....
I missed something when I tried to embed my pictures. For now, please look at the attached photos. Sorry about that.
*****EDIT****"*
there is an excellent video here
******UPDATE******
My apologies for not staying up on this. Life and my One+ One obsession got in the way. As
Refer to video link above for detailed instructions regarding hardware disassembly/reassembly process
I have ordered a WHITE replacement screen to test. Let's hope that it arrives with touchscreen issues.
I will update thread upon arrival of touchscreen.
****** EDIT again ********
Here is a photo album consisting of extra pictures that didn't make the guide. Some have fairly useful info as well as a few DON'T do this or you will break your phone even more pictures.
I've also added an update concerning reversed x axis starting at post #43
ID Numbers to compare
ID #'s are listed to the side. Again, sorry I couldn't embed them. I still searching for a solution....

To show pictures, like in @Ilxaot's post above you, they need to be online somewhere. Use the Image tag

Now as I write this, I cheated with the image in my last paragraph. I copied it from the editor, right click -> Copy, and then pasted it in to the edit box... Weird. That may work too. LOL

Using your guide, I successfully disassembled, replaced LCD and digitizer of my son's phone (like yours, sudden stop at high velocity) with Chinese purchased parts from eBay. BTW, didn't drop one screw lol. However since they weren't OEM parts, I've got the reversed touch I've read about and seen videos of (swipe right, screen moves left; touch right side of screen for a check box on the left side). Any idea of a fix? Let me tell you it was a pain signing into WiFi. Thanks for your guide and photos.

Maybe you can flip the digitizer 180°? I dont know if that would be possible (if the digitizer would even be able to fit in the phone the other way) but maybe it will work...

I gave up. You see, the eyeglass screwdriver I have is EXTREMELY small and doesn't fit in the screws perfectly, but it's the best I've got. Coupled with the fact that green LockTite is on the screws (green LockTite is the strongest LockTite they make), it pains my fingers to have to keep on jamming down on the screw to get enough of a "hold" on the screw while I turn it. Maybe in the future I'll buy a bigger screwdriver so I can have a better grip on it, but for now I'm done.
It's probably for the better anyway... I probably would have dropped the digitizer in the toilet or something if I got it apart.

Maybe you can flip the digitizer 180°? I dont know if that would be possible (if the digitizer would even be able to fit in the phone the other way) but maybe it will work...

Yeah, i dont recommend attempting cell phone disassembly while pearched on the "throne". Not judging! Just a personal decision on my part.
I wish i had the sense to know when to take that deep breath and calmly walk away. If i were in your shoes, the other 10 screws would be rounded out by now. There would be no accidental drop into the toilet, the phone would go down as the only l90 d415 to understand the meaning of swirly.... Wouldve made a great video though.

Using your guide, I successfully disassembled, replaced LCD and digitizer of my son's phone (like yours, sudden stop at high velocity) with Chinese purchased parts from eBay. BTW, didn't drop one screw lol. However since they weren't OEM parts, I've got the reversed touch I've read about and seen videos of (swipe right, screen moves left; touch right side of screen for a check box on the left side). Any idea of a fix? Let me tell you it was a pain signing into WiFi. Thanks for your guide and photos.

It looks like theres a flat connector between rhe 2 pieces. Perhaps it is connected "backwards"? I will look into it on my "donar" phone and see if i can figure something out. Will post findings within a day or 2.
*Edit - check @jasonmerc's reply as well. Good thought!

No that wouldn't work since the digitizer came with the double sided tape but thanks. The buttons also don't work and touch doesn't work at all with the phone laying flat

Oh no, I'm not disassembling it there XD I'm doing it in my room. Just a bad joke on my part... With my luck, I'd have the digitizer laying half-off my desk, and I'd accidentally launch it in the air my hitting my hand on the part off the desk. It would then travel in the perfect arc to the bounce off the hallway wall, enter the restroom, and drop in the "throne" because the lid was left open.
I think some of the screws are actually a bit rounded off, but not to the point of not being able to work with them. That's part of the reason why I'm hesitant to proceed; I don't want to round them off completely because my screwdriver doesn't perfectly fit. I'd greatly appreciate if someone told me the exact screwdriver they used to disassemble this, and maybe where it was bought as well.
If all else fails and something breaks or the screws get rounded off completely, I'll grab a sledgehammer and finish it off. I'll even upload a video of it (and call it "How-To: Quick Disassembly of the L90")

Hmm... Then there's gotta be some sort of manual screen calibration app out there. I'll look for one and post back if I find anything.

I found a thread talking about how to calibrate the touch screen of a chinese android tablet. I haven't read it yet, so I personally don't know if this will work or not for the L90, and if they do the instructions you will have to follow will probably be way different when it comes to actually calibrating. Quickly looking at the thread it looks like one will need ADB and a computer to do this.
HERE IS THE LINK TO THE THREAD
I'd say hold off on doing this until I or someone more technically experienced can confirm that this would work. If you do want to give it a go, please realize you are proceeding at your own risk.
EDIT: Having read the thread, those values for the screen are going to be different for the L90 since the screen resolutions are different. We are going to have to find the values for the L90 and then invert the X axis values and that should solve your touch screen inversion (we are basically creating a double-inversion. Who says two wrongs don't make a right?)

Figured out how to obtain th XY values for normal screen, if someone can figure out where modifications need to be made, Im thinking framework? The values for XY can be enabled in Developer Options - show touches and XY values. Turns out 10 taps to become a developer (its true cuz i read the toast) has other useful tools. I will decompile any suggestions related to touch screen calibration.
Brings back found memories of the famed L9 P769. It only took me 6 unintended 911 calls to reflash back to stock. Yep, 6! 5 with no sim. Took less than 2 seconds to pinpoint location on last few calls. 5 cars fully lit in my front yard and another 2 setting perimiter. Not once, but twice! Threat of jail made the choice to stop obvious.
"What are you in for?"
"I tried to unlock my bootloader." :cyclops:

I don't know, I think we just need to go to that file that is mentioned in the calibration thread, and whatever values are for the Y axis, just change them to a negative, since according to a video I saw of this issue with 3rd party digitizers in the L90 only the vertical axis is inverted (touch on the left side of the screen, and it registers on the right side). Of course, that is assuming that 0 on the vertical axis is in the middle of the screen. If not, then it will involve a little more math to get stuff right. Shouldn't be too difficult, though.
It's probably too late to suggest this now, but I believe GravityBox or some other Xposed module can remove the emergency call button from the lockscreen.
EDIT: Just checked the /data/data directory and I did not see any touchscreen calibration data folder. I did also read something about these Chinese android tablets coming with a TSCalibration2.apk (TouchScreenCalibration) program, so maybe you need to install that first before you can find the folder since that folder is probably the data for this app. I've had zero luck so far finding a download link for this file. Will report back if I find anything.

Truly appreciate all the work you are doing trying to help me out. I'm thinking its not going to be fixable. I would contact the seller and return the part, but return shipping to China would probably be more than the phone is even worth. I was even thinking to just put the original screen back on but the double sided tape is basically destroyed. It was only the LCD that was damaged in the sudden stop, the screen didn't crack at all.

I will be updating the OP to show FULL disassembly soon. I need to sort out the pictures and point out some things to watch out for as well as some DEFINATELY DON'T DO THIS items.
The parts that appear functional are availlable for donation, FREE of CHARGE (aside from the cost to ship via USPS flat rate box) to help another, less broken D415, continue life. The lcd assembly is yours if you'd like.
I will include a list of parts for donation in the OP.
Also, if you want to try tinkering around with the screen calibration, here is the TSCalibration2.apk (It is a system app from my VisualLand prestige 7L).

Don't toss it to the curb just yet. And the double sided tape is WAY easier to fix than UV glue! Thank you LG for that. I'm seeing low priced OEM glass for the D415 starting to show up on eBay and amazon, as well.
And I still don't know what I'm dong wrong when I try inserting full pics instead of thumbs!

Thank you for the offer! That is very kind of you, however, the lcd seems to function fine. It's the touchscreen that is wonky. As for the pictures, I use tapatalk, so I only know how to insert via the app which is
