LCD broke,does the liquid affect the PCB?? - PDA2, XDA IIi, 2020i General

hi there!
i got a problem.
my phone's LCD broke,does the liquid affect the PCB..?
i had send to the O2 center for checkup..they said liquid is on the board..will make the phone unstable.is it true? they cost me around MYR 2000 or USD 400 for the screen and PCB
Malaysia O2 center always like to "cheat" their customer. for example : actually my LCD broke,the technician said this will also acffect the PCB,you need to change it too.what you get i mean? they make is big problem..bcos this is the only place where can fix and get part.others phone dont service PDA.

MYR 2000??? Better you buy a new one....
My brother just repaired the screen too at Times Square O2 shop.... It cost him only 550.....

It is quite possible for the liquid crystal to adversely affect the PCB underneath, as the liquid is conductive - if it leaked onto the PCB, it could cause a short.
However, the likelihood of this happening should be low. I don't know the exact insides of the Alpine, but generally there is a seperator between PCBs and LCDs for spacing, and in the case of touchscreens to prevent pressure on the PCB. Unless the LCD was cracked wide open, then it's unlikely that the liquid crystal even got out to the PCB, let alone do any damage.

It is possible but not highly likely.
My line of work has me exposed to the basic production of PCBs.
PCBs have a layer over the wiring patterns. This is to not cause shorts should there be any part of the device to be loose and touch the board.
There are some exposed parts but too small to consider (these are usually test holes to check if the wiring pattern isn't broken.
The chips soldered unto the board usually get a thin layer of glue over the exposed metal parts. Again, to protect from shorts.
So it is not probable the LCD liquid will cause shorts to the PCB.
Although the PDA does have other parts that may have little or no protection from shorts. And those may cause a current build up and fry the PCB wiring patterns.
You should request to visually inspect your unit's PCB if they allow you to go to their work area. Also, have them explain in detail why and how your PCB is broken by the liquid.

hye kingrings... its better u go n repair ur pda at lowyat at O2 agent repair shop.. its cause 550...dont tell about liquid things.. just give them n ask them to repair.. in 2/3 days..they will tell u whats the real problems.... ok

HTC diamond water damaged white screen only???

help help help!
pm me and i will help.
there is a secret
ok calm down and describe problem in details not just a rough topic title and then help help help
Open back cover, let it dry for a day or two, try again, buy another
my unit is stil alive but has no lcd display
my friend (cp technician) opened it and we dry it using a hair blower but stil no display
i already tried google got no solution online can someone help me
Oh dear looks like you damaged the lcd screen from what your saying...if thats the case then time to buy a new one really. Unless you can track down a replacement lcd screen for the diamond from somewhere...get in touch with HTC and see what they say.
I hope you didn't cook it with the dryer! I have had this happen several times and a full strip and dry with a kitchen towel and a few days to dry has always seen them back to life.
you either need a new lcd screen, new flex cable to your lcd, new graphics processor, and then you will need to flash the rom

Please tell this "technician" not to use a hair dryer for drying sensitive electronics again in the future. Hot, dry air, when it hits the electronic components, will cause build-up of static electricity. Also, the hot air will probably fry up the components before all this anyways. Good luck !
So how do you recommend to dry it if I ever encounter such a problem. Just take out battery and cover and let them dry naturally on the table for some days?

Yes, thats the best way, you can in some cases use dry air to blow water away
How to or not to Dry!
Look using a hair dryer will not do any harm to the components on a pc board those pcb's are mass produced they are flood soldered at about 350 to 400 degree's which is about 250 degree's hotter then a hair dryer can get. the only thing you need to worry about is getting to close to the specter strip (film cable) that can melt much lower and the lcd is 2 pieces of glass with liquid between them, heat that up and the liquid expands and crack no more display. you were correct in drying it quickly if you leave the water on the board it will begin to oxidize at the solder points and then when they (Warranty repair personal) see that ,they will tell you it is not covered. the only problem you have now is returning it for warranty exchange, there is a small litmus like dot (tab) under the battery on most phones I am not sure where it is on the Diamond but it's there. which turns color when it comes in contact with moisture that is how they know it has been exposed to water. So if they (Carrier you got the phone with) send you a replacement handset ,which is what a lot of Carriers do with phone warranty's , they send you an exchange unit, you send back the bad one and you keep the exchange. then just use a small razor blade and remove the good water dot from the replacement unit and switch it with your bad phone before you send it back to the warranty dept. As far as they are concerned you have a Diamond with a bad display.
PS. When you call to setup the warranty exchange the tech is going to ask you what color the tab I referred to is. so you need to find out from someone that has a Diamond what color the dot is ,so you can give the tech the correct answer. Hope this helps.

Thanks Ed for the sensible answer based on knowledge and understanding, "Replace" is the easy answer based on ignorance. People replace lots of stuff unnecessarily IMHO, bad for the environment and your wallet too.
Also note that rubbing alcohol (methylated spirit, isopropyl alcohol) is a strong drying agent, it bonds to the water molecules and removes them by evaporation. I fixed a mobile that had been wet many months before and it cleared up the board damage shorts.
Knowledge is power, fight ignorance

How do I replace Digitiser/Digitizer/Touchscreen overlay?

I have had my phone open a few times...
1) To replace Vario III case with Kaiser case
2) To fix faulty keyboard, had to bend some of the aluminium on the bottom of the keyboard unit.
So I know my way around inside and haven't broken anything... yet!
Anyway, my screen is very scratched so I want a new digitizer, they're significantly cheaper than a whole LCD assembly. I got one for £5, the assembly is over £30.
I did read on some thread that the digitiser WILL perish as I separate it from the LCD screen. Is this true? If so how easy is the clean up job?
Also, the official kaiser service manual shows the LCD and Digitiser held together with tape on the outside and not double sided tape or glue like the actual assembly looks like.
Has anyone done this before? Is there a decent risk of damaging the LCD itself or to be on the save side should I just buy the whole assembly?
I have the digitiser here and ready to go as long as I can get some info from someone who has tried this.
Cheers
Sorry bump.
to be honest there will be soldering involved and u need special equipment for that ribbon
look at http://rapidshare.com/files/103168855/HTC_Kaiser_Service_Manual_jas_pik.pdf
there is detailed procedure and all the tools needed, i believe the tools are basics, and i dont think they will be expensive to have, as matter of fact, i think buying a tool box is an asset.
best luck ...
Hi!
The service manual linked to does not specifically contain information about replacing the digitizer, just how to assembly it.
Do I need a certain kind of black tape to attach it? Is that the only way it is connected to the LCD itself?
Mine is also very scratched, and I would like to replace it, preferably done by myself.
Any tips?
Cheers
a good insulation tape (anti-static prefered) will do the job

[Q] Streak replacement capacitive buttons.

I damaged my Capacitive buttons (flex circuit).
Can anyone recommend where to get a replacement part?
Lol. I did the same thing. Ladies and gentlemen please wait for the plastic tool to arrive in the mail before you start trying to disassemble your streak! I used a screwdriver and it cut through the flexible circuit card. Contemplated fixing it, but there`s five tracks on the circuit board!
I got a quote from an ebay seller in the UK for the capacitive buttons and plastic bezel. 90 pounds plust postage. What a rip off! I ended up buying a complete streak from ebay. It was locked to O2 and had the lcd bleeding problem, but perfect for me. Keep your eye out.
In the meantime, install softkeys from the market. It is a replacement home/settings/back button. A little inconvenient, but keeps you going while you bide your time on evilbay.

My first streak also has a broken capacitive circuit board, didn't use this plastic tool for disassembling..
Now i use a old modified tooth brush
Was ready to ask a flexible board manufacturer what it would cost to reproduce such a circuit but for now i'm also using softkeys..
Maybe if we get 100 people together who needs one of those capacitive button circuits its worth asking a reproduction?
Thanks for the inputs. I got the key to work again after some fiddling. I'm just waiting for it to inevitably fail. I'll probably just get a new phone when that happens.
how do you get it broken? not that i wanted too, but it sound strange to me
Sent from my Dell Streak using XDA App
Pretty easy... First time pulling it apart, had not seen any videos of the process. Fixit. Com (OR IFIXIT?) wasn't that comprehensive. Of course I was overtired and of course used a small screwdriver instead of a plastic removal tool.
Excuses, excuses. The screwdriver ultimately was the wrong thing.

I broke my capacitive button ribbon cable, anyone have any luck finding replacements? I'm going to try to repair it.
Wheeew, just finished repairing my broken cap buttons. Most nerve-wracking soldering job ever.
I managed to tear through 5 contacts on the flex PCB when disassembling the Streak because I didn't bother to read the obvious warning about this on ifixit Also, I was taking the week-old device apart for no good reason, so I had it bloody coming, really. Anyway, even with a high-quality soldering iron and a stereomicroscope this repair was a massive pain, but it is doable.
I think it should be possible to repair even a completely broken ribbon - I would scrape off the plastic off the ends of the tracks and then glue the underside of both halves of the circuit in place (or tape together if not possible). Then you need to tin the tracks with solder - plenty of flux helps. After that it's the difficult matter of bridging the broken tracks with solder blobs or tiny pieces of wire while not shorting across them. Finally a layer of epoxy to secure it all. Not even worth attempting if you don't have a really good soldering iron and a microscope. Can't use too high a temperature or the plastic melts. I did the repair with the phone assembled fully except for the bottom panel, flex PCB attached to phone - the broken area was still accessible for me and this way reduces the risk of breaking contacts during reassembly.
Hope this helps someone!

I think I may attempt this...$40usd for a new assembly is a bit high...
You can find the top/bottom parts on Ebay and on Lingosbox.com
I've purchased some spare parts for other phones on lingosbox - they are not genuine oem parts but for this price, it's a bargain for replacement parts that are rare/difficult to find. There's some delay(15-27days) but everything has arrived without any problem.
good to know someone found it cheaper

I9305 front replacement identical to I9300?

Hi there,
I'm looking to replace the broken glass front of my gt-i9305. However, most parts I find online explicitly list the i9300 unit.
Will a i9300 glass front fit the i9305?
Thank you for your input,
Gnaddel
Hi Gnaddel,
First i would like to say that i am no expert or authorized in this filed but as far as i know and checked in the internet,those 2 models are exactly in the same dimensions and the only different is that the radio/modem is Qualcomm brand and not Samsung.
So i think it will fit
http://www.gsmarena.com/samsung_i9305_galaxy_s_iii-5001.php
http://www.gsmarena.com/samsung_i9300_galaxy_s_iii-4238.php
Only differences are the motherboard and the antenna module.
All I can say is that when I replaced the screen for my i9305 they told me the part for my phone was a little cheaper than the one for i9300. And that was an official Samsung service center. I asked why and they didn't really know the reason. At this point I'd say they are different.

That's probably because they sell more i9300's than i9305's so they charge more for the screen to make money.
I did see one guy selling an i9300 screen on eBay because it didn't fit his i9305. Not sure if they just didn't know how to fit it properly or if they actually don't fit. I would think that they would fit because its exactly the same frame. Its only if the extra components need more space to fit in the phone.

I doubt they've been successful repairs that's went off without a hitch in that case..
The thing is the back of the screen on the i9300 and i9305 differs a slight, (i'm talking about the iron/steel bit on the back of a complete assembled screen) this won't accommodate the motherboard on the various units .. apparently the i9305 has a few more transistors or the like on the motherboard..
Example: i9300 screen assembly, i9305 mid frame..
The motherboard wont slot down properly, leading to the bottom left corner (Seen from behind) to not go down properly, which in turn leads to the mid frame siting a slight skewed, which also means that the battery cover won't fit properly, as the bottom left corner will be lifted enough to where it might fall off without much strain.
This is due to the the ironmolding on the back of the screen assembly being slightly different from the i9305 device, which fits the additional capacitors and so forth better.
,
,I can .. if requested provide photographs of the differences i'm referring to, as I've a number of screens in-house.
I have also i9305 and my gf has i9300.
i bought some screen protectors and put them on both phones.
on the i9300 fits nice.
on i9305 the edges of the protector do not stick on the screen. and it now has a non pretty margin of unstuck plastic.
it happened after multiple tries with many different protectors.
so i assume that there is a difference betweenthe two screens . some kind of curve is on ii9305 screen.

We are talking about two different things here.
Some people are talking about the front glass. This is exactly the same for both models. The S3 LTE (i9305) is the same design but altered for 4G so the motherboard and some antennas have been altered and the metal frame and some other elements needed to be altered too to accommodate the alterations.
Battery and battery cover are also the same. Also the cameras, speaker, vibrator and wifi antenna. I'm not sure about the LCD screen and touch screen but I would say hey are the same too (I'm talking about these two elements alone, not the frame)
If you try to fit a regular i9300 front (frame, LCD, touch screen and glass) to a i9305 motherboard, you will find it doesn't fit perfectly. Main problem is in the different disposition of the big square chips in the motherboard side that touches the front frame. i9300 frame has a rim around those chips that touches the golden line in the motherboard that surrounds them. Just over the microUSB housing there is a part of that rim that enters the squared perimeter. That piece of rim has been removed so the rim in the i9300 frame will avoid the chips in the i9305 motherboard to fit there.
The lower left corner of the frame, near the screw hole, is also a little different, again due to an alteration in the rim.
Finally, the i9300 frame has a tiny metal bit in the very lower left corner, near the mic that avoids the plastic back middle cover of the i9305 to fit perfectly. that's because this cover houses at the bottom an antenna (I guess this is the 4G antenna) that is slightly bigger that the one in the i9300. You can think you could use the i9300 middle cover instead, but then you would be fitting the phone with a 3G antenna instead of 4G. what's more, this antenna has 3 points to connect with the motherboard while the i9300 antenna has only 2 points.
The reason the home button doesn't work is because the home button is not connected to the motherboard through the main connector but using two spots that you can see just over the mic white rubber housing. since the motherboard is not down to the position it should, it will not touch those spots.
Still, I believe there is a solution and it consists in using a Dremel tool to remove all the aforementioned parts of the i9300 metal frame so the i9305 motherboard and middle cover fit correctly.
Some precautions have to be taken. Covering the holes in the frame to avoid metal splinters entering the LCD circuits and painting the removed parts properly to avoid contact of the metal with the motherboard circuits.
I haven't tried it personally but I'm probable going to do it this weekend so I will tell you how it goes.
And next some pictures illustrating everything I explained:
Thanks for this, jedikalimero, this is exactly the information I needed.
In theory would it be possible to disassemble the entire front assembly of an I9300 to get the digitiser and screen panel out and attach to the front assembly of an I9305 so the gaps match up on the board?
Pretty much what I'm thinking of doing is replacing the cracked digitiser of an I9305 with the digitiser of an I9300. As you have shown, the front panel assembly would not be compatible, but I was thinking of disassembling the I9300 assembly and doing what I mentioned above.
I know the screen assembly is quite difficult to take apart as a lot of it is held together with glue rather than screws so it might not be worth the effort. Just thought I'd ask anyway.

Forget it. It is practically impossible to remove the lcd and touch sensor from the frame without damaging them. Even removing the top Gorilla glass is a very difficult and risky task since it is fully glued to the touch sensor and this to the lcd and this to the frame. Not only the edges but all the surface. Samsung worked very hard to make the front assembly unrepairable.
You could buy just the lcd and touch sensor and put them in the emptied frame of your broken screen but you still have to save the touch buttons and put a new front glass. I've compared the prices of the lcd+touch sensor assembly and the prices of the full front assembly and it isn't worth the effort. Just buy a front assembly for your S3 LTE and sell the broken one at ebay.

I tried it a little differently:
Instead of removing the metal legs on the display, I put some clear tape on those areas causing a short on the mainboard. As this doesn't make the PCB fitting mechanically to the display, I didn't tighten the black center screw very much. If you then use a dremel for the midframe, everything works technically and also the gap on the left bottom disappears.
I was afraid of metal flitter in the electronics when cutting the metal legs. Obviously, the mainboard is very robust. Even tough I caused several times a short by the wrong display, everything is still fine....

not 100% sure but the tracks that can be seen under the white paint (or black paint) on the outside of the piece are different in shape from i9300 to i9305
What is sure is there is at least one antenna inside the piece, maybe two
Jedikalimero,
thank you very much for this info & pictures!
I've applied your solution (Dremel tool, holes covered by clear tape and then to isolate chips and brushed parts) and it works like a champ!

From the photos I have inspected,the number pins in that particular assemble in i9300 n i9305 are the same and appeared in the same place. Can't judge from 9300's photo though. In fact in my i9305, that part say i9300 on outside.
Not sure if my unit had been tinkered before as i bought it as a 1month old 2nd hand unit.

HD2 T-Mobile US (1GB) - LCD+Digitizer GLASS Replacement Part

Hi to all,
Before you ask, yes!, I did use the search and found some related posts to my issue, but a little outdated and I read so many things that I think I'm more confused.
My HD2 works without problems with the broken screen...but unless i have tape on it, i I'll cut my fingers...so after almost a year i decided it's time to repair it!
For that, I WANT to buy an LCD+Digitizer Glass Replacement (because i hear some are made of plastic). Because there are at least 3 different versions (so i heard) of HD2 LCD and hundreds of listings on ebay, I'm afraid to buy the wrong part.
Correct me if I'm mistaken:
There are 2 types of connection, solder or socket type. Mine is definitely socket (60H00300), correct?
Every socket version (60H00300) is the one that the LCD is better, right?
If i purchase any LCD+Digitizer combo that states as "for HD2 T-Mobile T8585 solderless/version 2/socket" will it be ok? Even without the T-Mobile logo on top? ...I ask this because I know for a fact that the US T-Mobile version has a slightly larger screen/digitizer!
Plus, I would also appreciate if someone pointed out an original screen replacement (meaning scratch resistance glass digitizer) that i could buy with confidence! :highfive:
Here's my sad HD2...i had to put tape on it, or the top right corner would fall in pieces..
Your TMOUS LCD & Digitizer is 100% same size as any other model HD2.
size difference is in the casing below the buttons & is about 1.5mm to allow for different antenna setup on mainboard.
Any 300 type will fit & work fine but you are indeed correct in assuming issues on quality & materials used.
Buying complete LCD/Digitizer does not mean you will get better quality parts & to be honest it maybe worse as the quality of tape used on some of these is poor.
If your LCD is fine I would make the effort to remove the Digitizer & thus just replace digitizer.
Can be done by warming it up with a quality hair-dryer & using a few new razor blades to loosen the bond, time & care is the key here.
Tapes for rebuild can be found on eBay from poland with worldwide shipping.
Digitizer for TMOUS is this one:

You would be advised to use a film on lens as even the glass ones can scratch as not as hard as original.
Trying to find original is a pain & high cost for possibly no gain ...
Most important part is learning good repair steps & using good care when stripping & rebuilding as without that a good or poor quality digitizer will be just as useful as a beer mat.

The main reason for me to buy the LCD+Digitizer is that i cant afford to be without my HD2 for more than a couple of days...and if I mess up ending the relationship between the LCD and its digitizer....I may end up with two (or three) broken "hearts"!
I'll risk in buying an LCD+Glass Digitizer "300 type" (+film protector) and then attempt to recover the original LCD for a "future repair" as you suggest!
Thank you for your reply, it really answered my issues! (I pushed the thanks button...but for some unknown reason to me it didn't work )

Good luck, hope it works out fine ...
hi
my display was broken, but have worked for a year or so.
now it is frozen/ unresponsive and i have purchased a full display.
just found a very easy way to replace the whole display in just 3 minutes by accessing it from the front side..
i am not yet allowed to post the link, but if you google this
IMPEXTROM CAMBIAR TROCAR DISPLAY HTC HD2
you will see the 3 minutes video
but it seems too easy to be possible ...
any hints?
thanx &cheers
That been set up for the video as you can see it been off before & the chassis the lcd is bonded to is clean of all bonding tape :-/
Also original has signal interference tape runing down sides across all 3 layers.
also if you heat the front first thing to seperate is the digi from LCD as the lcd to mid chassis is a strong bond.
Best way is popping them out of rear cover, fitting a pre built lcd/digitizer is not hard, just use quality adhesive to hold lcd to centre chassis & buy pre cut black foam tape for the top & bottom digi glass edges or rebuild is next to pointless without this done well.
I've done a good 30 odd HD2 screen & mainboards & no way I could do it to my standard via that video.
