Help! Help! Alpine Touchscreen dead after cleaning... - PDA2, XDA IIi, 2020i General

Hello, I have a XDAIIi. I recently wipe its touchscreen with a special liquid that said "Specially for electronic cleaning including cellphones and laptop screens". Now the touchscreen is dead I tried to soft reset it hundreds time but it's still doesn't respond to any touch. Pliz help....

Sounds to me like a contact problem somewhere on edge of screen - possibly the cleaning disturbed things causing it to pack up.
I guess an alcohol clean of screen edge contacts may be needed - might be worth getting a quote from a service agent as disassembly probably necessary?
Maybe someone can advise?

If you are feeling adventurous the Service Manual with piccies is here:-
ftp://ftp.xda-developers.com/Himalaya/Himalaya-Service-Manual/
Page 28 gives the short form explanation - looks pretty involved though when you look at precisely what is involved in the preceding pages.
Might be worth trying a careful clean of screen edges using a sharp wooden cocktail stick in case any wedged in fluff or detritusis can be fished out....you never know!

how do i separate keyboard from screen - xda11s

I dropped my xda2s into a basin of water today
I was able to drench it with isoprop alcohol and have been drying it with a hairdryer .
after about 5 hours I was able to boot it up and got the first windows screen . that was when i noticed the water logged screen.
I would like to split the machine so that i can dry each bit properly.
How do I separate the two parts?
many thanks
With the two hex-type screws on the sides of the PDA (one on the left, the other on the right side).
many thanks
I have removed the two screws. now what do I do? i am afraid to break the unit, how does the screen section clip off.
I have an XDA2s with a sliding keyboard
many thanks
I've had to take mine apart too. Problem is, you need a good memory and fine fingers.
The 2 screws that separate the keyboard unit from the screen are only accessible AFTER you've removed / loosened EVERYTHING else - including internal boards, cables etc.
I did it OK - but need to get hold of new buttons - contact cleaner ruins the silicone button 'diaphram' thingies.
Us Perth people must be crap with our XDA's - I got red wine over mine.
hell, I'm not lloking forward to that. I need to repalce the screen because I now have dark splotches in parts.
The phone answer button does not work so I will give it a clean.
I learnt a very important lesson with this problem about not having all eggs in one basket. My T630 arrives next week. the xda will become what i think it 's ideally suited for:
diary, notebook, the odd calculation, wireless work and backup phone.
The absence of integrated voice dialing and the ability to easily make a call with one hand make it too clumsy for me coz i make many calls on the road
what did you use to clean the switches?
Hope it was a good red wine

TyTN II Screen Broken.... sort of

Hi All
Spent awhile searching the forums (and the web) but couldn't find any relevant answers -- so here goes & apologies if it has been up before...
My TyTN2 got rain on the screen a few days ago (about 15-20 drops) and since then the touch part of the screen no longer works. The phone itself works perfectly, the screen displays everything as it should, but no touch.
Could a few raindrops do this?
I have a Hermes/TyTN 'lying around', anyone know if the screens are the same/compatible, was about to start searching for part numbers etc. but thought I'd ask the question anyway.
Any help, answers, pointers or links would be appreciated.
TIA
You could always buy a new touch screen.
I saw one at dealextreme.com for 4.99 , probably not the best quality but you can always give it a try for that price
sku.14919
cnn.cn also has the part , but only in combo with the actual lcd screen.
Thanks RacerII -- will check it out..
Had a similar issue with the touch screen dying after an os crash the other night n thought it was dead. Did a hard reset and reflashed and everything worked just fine. Try the hard reset and reflash first before you think about any repair options
@kaalgoosy
Thanks for the reply -- did a hard reset as you suggested, no change -- about to try a reflash -- currently using L26's B1 ROM, have dl'd B4 and will give that a whirl -- only problem seems to be I have to bypass the Welcome/Screen Alignment section (no touchscreen!) and Activesync seems to be lacking/missing/not working -- so can only try the SD method -- just reading up on that now
ROM update made no difference (wasn't holding my breath anyway...)
Looks like a screen replacement, after looking at the potential difficulties separating the digitiser from the LCD, decided a straight LCD replacement is my best option -- have found a place that will supply it (London UK) for £30 + p&p -- anyone know of a better (read cheaper) supplier?
Intending to use Mike Channon's guide to replace it myself...
no few drops of rain wont cause that damage...
most new PDAs and new gadgets in general including cams, portable ps... etc has a elements of water resistant+shock resistant and even an anti-magnetic field absorbtion (or something like) to reduce interference with other devices...

get your phone inspected by a professional technician especially if under warranty (dont tell them it was affected by rain drops.. they wont know) it might not be a very fair thing to say but again who said life is fair

Have you got a web address for the London supplier? I think my screen may be on the way out.
Good luck with the replacement.
@jahrami -- was using the Kaiser's camera to take some photos for my daughter, it started raining while I was taking the last couple. 15-20 drops or so (as I said). Dabbed this off with kitchen roll, put the phone away. Got home a little later, tried to use the phone, no touch -- played around, soft reset etc etc, but nothing.
The rain is the only thing that has happened to it -- the display is perfect, phone itself works perfectly, have hard-reset, reflashed ROM, still no touch control... and while in theory I agree with you that a few drops of rain _shouldn't_ cause this sort of damage, it seems it has. Checked the water damage strip behind the battery, it's white, assume this goes pink/blue or WHY when exposed to real amounts of water.
Sadly, warranty is out (by 1 month) & the local phone shops want £40 to strip it and look... £32 for a screen? I'll do it myself -- if it doesn't fix it, back to the Eten M700...
@ach2 -- tried to put a complete & direct link to the item, message box wouldn't accept it (very long url). This company sells on ebay too, slightly cheaper (27.99 +p&p) and under various other site names, feedback is positive and screens are new. Can't comment on the company personally, unless you wait for a week. Thanks for the good wishes, will probably need them.

OP:
Before you buy anything for 27 quid: Note that there are 2 elements to that screen, as was mentioned (but maybe not quite clear) in post 2. There is the actual screen, which is a liquid crystal screen with thin film transistors with a glass plate on top, but on top of that is a digitizer. The digitizer is literally 2 sheets of slightly conductive plastic put together to assess where the stylus (or your finger) is currently touching it.
The digitizer shouldn't cost you more than about 5-10 quid. The full screen is going to cost you about 30 quid. You definitely don't need a new screen.
I've replaced 2 digitizers and 1 full screen on my HTC magician (I'm very good at smashing it into things) and after I broke it again, I bought a used HTC tilt cause I felt that an upgrade was in order. I ordered the digitizers for the magician and the screens from a generic eBay store in Hong Kong, it arrived the US (Boston) after about 2 weeks, I would expect Old Blighty to be similar.

One more suggestion for you: have you considered using a virtual mouse cursor program? Maybe VirtuaMouse One-Hand?
Of course it won't actually "fix" your screen, but at least you'll be able to tap around your PPC until you fix the touch panel itself.
i will agree with such a temporarily fix, use a combination of virtual mouse
and voice commander and hotkeys shortcuts to navigate through your phone
look for second hand screen, there must be some around dude

@incdoc -- Greetings to you too, cousin -- yes I do realise the screen has a separate digitiser (see quote above from earlier post), and in fact, the same supplier has digitisers for £8 but after reading about the difficulties of separating the digitiser from the LCD thought I would save time, effort and money by replacing the LCD in its entirety. I can always play with the older one afterwards, and if I successfully split them will get a touch screen and keep the thing as a spare, which seems like a good idea, as there are now several more posts regarding the same or similar issues to mine, just within the last few days.
Are you suggesting that separation _isn't_ difficult?
@EGMine -- have to say that I haven't heard of VirtuaMouse One-Hand, will look it up -- thanks for the suggestion.
Jahrami -- thanks for the suggestion, about to check VirtuaMouse and completely forgot about Voice Commander, just changed my ROM to L26's B4, (after fault developed) so haven't set the phone up, yet -- but definitely will set up some voice tags.
Big thank you (for telling me something I should have thought of myself -- age really is a bummer!)
Edit** Dl'd trial of VirtuaMouse, good idea -- hard work! Combination of Voice Tags and scroll wheel much better. Eten M700 back in cupboard. ;-))
Dammit, dammit and dammit!
In the interest of rounding things off -- thought I'd post this to (almost) end my (little) epic.
Bought a replacement screen from the source listed above, £32, web price was lower with free shipping, but phoned the order through to get a quicker delivery. Arrived the next day, exactly as ordered. (Bravo!) No tools included, but I have some anyway.
Used Mike Channons guide to replacement (no mention of the sticky keyboard hinge 'finisher' anywhere BTW), all went as planned. Total time to replace about 1hr 15mins. (Not rushing)
Screen kicked in, onto alignment and yippee! -- touch working again!
Knew I shouldn't have had that celebratory cup of tea! -- put SIM in, followed by SD card, phone no longer recognises the SIM. Bu**er!
Stripped the phone again (impressed myself, took less than 10 minutes), checked to see if the SIM ribbon had popped off -- seemed ok, but popped it and reseated it anyway. Reassembled the phone, popped in the SIM -- Bu**er again.
Stripped the phone again (4 minutes -- not bad eh?), checked the SIM connection to the keypad PCB and 2 of the contacts in the socket look slightly mangled.
At this point now I'm wishing I'd gone for the £70 repair option, it's 20 to 1 in the morning (12:40 am to you), the eyes are a little fuzzy and I (once again) have a TyTNII 'kit' in front of me.
Oh well, there's always tomorrow -- now where did I put my Eten M700?
EDIT** Forgot to add a request, if anyone has a TyTNII in bits and wants to sell the keypad PCB, leave info or PM. Thanks.
EDIT 2** Oh well, seems like I _have_ kiboshed the SIM socket on the keypad PCB -- so hoping someone has one (keypad PCB or TyTNII) lying around will sell for bits?

Droid Turbo Motherboard Layout (where is wifi?)

Hello Everyone,
I have been unable to find this information anywhere so I thought if anyone knows this would be a good spot for it. So a quick back story, my turbo took a dip in a hot tub for about 5 minutes. I put it in rice as quick as I could (about an hour) long story short it was completely dead unresponsive. I ended up doing a bunch of research and buying an ultrasonic cleaner, taking it apart and cleaning it soaking in 99% isopropyl. I did that several times and each time more functionality returned. At this point everything works perfectly other than wifi and bluetooth (presumably on the same chip). They are both permanently grayed out and cannot be turned on. I would like to know where physically the problem is before attempting anything further.
So can anyone point out the wifi, bluetooth and antenna for each on these pictures? I tried to post in pictures but it seems I cannot because I am a new user. I think you can copy and paste these into browser though or maybe someone else can post one in for reference. The first image is the back of the screen as well as the little cover that goes over the battery. The second is the motherboard.

Oh and while Im at it does anyone think there could be a software issue resulting from water damage like would I need to reflash some drivers or something?
All help is greatly appreciated!
Im going to try contacting motorola and ill update post if I have any luck
You should try flashing the software using rsd and doing a factory reset! Doubt Motorola will be of any help cuz u void the warranty when u take open ur phone and I don't think water damage comes under warranty!
Are you sure there is reason to believe this could be software related? I just finished rooting and getting everything set up, itd be a shame to start over.
Motorola was no help of course said its top secret. Is there no one out there with the electrical engineering or phone repair background to tell where the chip is from those pictures?
Nobody will know from those pictures - all of the IC's are hidden under the metal shields. Your best bet is to check out the FCC filing pictures of the phone, there should be some with the shields removed. If you can read any of the #'s start googling them.
Or find someone else who has taken high-res pictures with the shields removed, chances are they are out there.

An confusing issue regarding the infamous phone screen - Presses itself erratically

I want to give some context.
I have owned my Z1 since release on a contract. I have previously had the screen replaced twice and it worked fine afterwards.
However, I had dropped the phone resulting in the top of the screen cracking. Got it replaced by a local phone repair shop.
The result was a new phone screen, a white edge just over half way down the screen might be worth noting. The repair man said it was a warranty sticker on the screen they put in. (Sounds silly)
Anyway, the resultant problem is not exactly like what i've seen on many threads.
My phone now decides to press itself erratically. Usually after swiping and trying to press delete on the keyboard would it start acting up.
My remedy: Hard reset(Didn't work), factory reset(didn't work), upgrade from 4.4 to 5.1(I think, newest software) and to my surprise the issue remains. So after the repair man replacing the screen twice and ensuring that i'd done my best with little to no phone knowledge, I still have this problem.
There's many threads detailing problems, some linking to apk's that are "calibration software", some that say you can change calibration.ini but no helpful replies or expanding info on the threads.
Can anyone tell me if they've had any luck with this or anyone who has knowledge of what I should do next (E.g "there's no fix guy, you'll have to sell it and move on") as i'm starting to assume these screens are very tedious to deal with
Remove the plastic protector and put a tempered glass protector

New insight on fixing phantom touches issue on HTC smartphones(a case report)

Greetings. I decided to make this post because I had this issue, found no solution online, but then accidentally stumbled across it by myself and I think that it might be useful for other people too.
I have been using my HTC One M7 for more than 4 years without any serious problems, but about a month ago it went crazy: I was watching a video on Youtube and it suddenly stopped and chaotic stuff started to happen, it looked like someone was touching the screen. That input was so intensive, it rendered the phone unusable, yet I managed to turn on the screen draw test and saw that it was just a single horizontal line that had been constantly "pressed". I looked up on the web and found that many people had similar issue and that it was called "phantom" or "ghost" touches. It seems that the same problem could be caused by several different reasons: bugged software, failed hardware, static electricity or dirt under the screen. Since I hadn't installed any new apps or changed any system settings for a long time it was clear for me that something goofed in the hardware. I planned to change the screen of the phone, but since I am a cheapskate, I decided to try one thing before buying new screen...
Since the issue could be caused by dirt or grease builduing up under the screen, I decided to try to clean it, so that is what I did:
I took a piece of cotton wool and soaked it in alcohol(96% ethanol) and rubbed the edges of the screen thorougly so that as much alcohol as possible get inbetween the screen and the case. Pure alcohol conducts electricity etreemly badly, that is why it didn't cause any short circuts, but I am not sure if the same apply to more dilute alcohol(especially when it dissolves some componens of dirt). After that I left it for several minutes and then took a hair dryer(1500w) and heated the phone with it for 3-5 minutes. Then I let it cool for half an hour and turned it on. To my surprise the phantom touches were gone and the results have been stable for more than 3 weeks( there was only one short episode of phantom touches on the first day).
So that was my experience with that problem. I assume that similar issues could appear in other phones and in some cases this can be the solution. I am really not sure that my theory about how this works is right and that it is safe, so please keep in mind that this method may damage your phone. I would appreciate any feedback or opinions on this. Also sorry for my bad English.
