HTC touch diamond water damage

Hi everyone!
Sad thing happend with me, 4 days ago i fell into a river and sadly ma diamond was in the pocket. I dryed it for three days, turned it on, everthing else works, besides the screen light. So i dissambeled the phone to bits and pieces, only i didn't took the LCD out(read it from somewhere that you can't put it back on afterwards so it will work). I reassambeled it and still same situation. If you look it from a angel you can see the icons and even touchscreen works. Only problem is still the backlight. So is there something i can do to make the backlight work again or i have to buy a new screen and is it hard to swap the screen ?
Hi,
Not sure if you will need to replace the screen, if you can get to the power settings you can see if the backlight has been manually turned down. If this fails and a screen replacement is required i will tell you how easy/difficult it is once i have replaced mine, due to unfortunate circumstances.
yeah, i got into the power settings, everthing is okey there like it should be , so i have to change the screen. Is there some kind on intrcutions for changing it? it would help me a lot

touch screen not responding

Well ive had my phone for a while with hyperdragon iv iolite working completely fine without any hardware or software issues for months. Today i took out the battery of the phone, and put it back in and turned it on, but when the phone turned on, the touch scrren is not responding to anything. everything works fine with all the buttons and keyboard, but the touchscreen isnt working. What could have gone wrong just by taking out the battery. I also havnt dropped or damaged the phone in anyway so i dont see it being a hardware problem. Thanks. I really need help
I have heard of people who has been able to solve this problem by hard resetting the devise. I have had not such luck....comes to be that from sliding wear and tear the connector to the screen gets damaged. My screen is completely disable, I found someone that was able to buy a second hand phone on ebay and was able to switch the connector. Looks like to much of a hassle to me, so Im sticking with this until I switch phones.

[PROBLEM] Died?

Hey guys, I was wondering if somebody would be able to maybe help me diagnose the fault\problem part with my non-working diamond...
Basically I went to a club one night and the place was unbelievably steamy / humid. My phone was working one minute and then the next it wouldnt display anything on the LCD. The backlight was working however.
Since then I havent been able to get an image on the screen although when trying to turn it on, it seems to go through its startup sequence (backlight -> vibration -> beep (i think))
I havent had any power to the phone since a day after it broke (a few weeks ago).
I'd like to get it back working again but dont know exactly what part i would need to replace. I'm fairly competent with electronics .
Any help/advite would be appreciated!
Haha, ok that's odd...
I've plugged it into my pc to get some data files off about an hour ago.. forgot about it and just looked at it now and the screen is displaying!
It is displaying and accepting input although it was flickering at first (like pixel shifting). but i pressed the power button to standby the screen and pressed it again and the display is fine with no flickering ?
Ive moved the phone about and shook it quite hard to see if there's any loose connection but the display still seems fine..
Anybody have any ideas as to what it may be?
I'm not going to deem it as fixed until I know what the problem was/is lol
cheers guys
Ok screen actually keeps flickering nonstop, and sometimes 'fades away' to gray/white/black
comes back after a few seconds though
Looks like a faulty connector?

Can anyone help me?

Hi i have had an x1 since august but within a month its been dropped and then it was unable to show the screen, i opened my device to try and fix my problem but messed with nothing whatsoever, when i put everything back together it wouldnt even turn on anymore! all it did was charge and when it was fully charged there was a red light. can anyone help me? please im desperate to fix my phone. My first paycheck was spent on this and i loved it despite the numerous flaws! also i havent charged it in over 2 - 3 months. Also when i opened it the tape that connect the rear and the front is kind of messed up, would that effect anything?
The tape that connects the front and the rear is the cable for the screen, so if it's messed up, you might need to get a replacement.
here is a pic, the red part where its circled is where i think the problem is, it looks ripped off, i did have a hard time opening and putting it back together the first time also.
Sounds like (Or rather, looks like) you're screwed, as far as I can tell, if it's really ripped. Otherwise attempt to clean the contact points with some cleaning alcohol and Q-Tips - something might have made it's way in when you disassembled the unit and blocked the electrical signals.
ill try it, but if that doesnt work, would i be able to replace the flex ribbon? would acteone work?
got this checked out by my friend, he told me its the flex ribbon cable, thanks for the help btw. Does anyone know the cheapest place to get a flex ribbon cable from?
Still would like confirmation if its my flex ribbon cable before i spend 40 bucks on a new one. thanks!
Hi, I am new to this forum. Sorry for posting here but I think I have similar or same problem with my xperia. Few days ago I drooped my xperia and then I could not turn it ON. I opened unit, the flex cable was detached.
After attaching the flex cable. I could turn the unit and it booted normal but no response on touching screen I even tried to align it but it did not respond. I turned off the unit. After trying turning it back ON only back light of the screen turned on (no sony logo, no xperia logo no winmo).
I tried to turn it on few times but same result. Even tried to soft reset and hard reset it but no difference only back light. Is it because of flex cable or because some thing else? I can`t even go in to 3 color screen. Please help. Sorry for my bad eng. Thanks.

Cannot use touchscreen with keyboard out

I don't know when it started but I'm quite sure that I used to be able to use the touchscreen with the keyboard extended. I am running the latest hboot and radio with the cyanogen nightlies and newest pershoot kernel.
Is anybody have this problem?
Perhaps I just need to reflash radio and hboot but its weird because it works fine with the keyboard closed.
Thanks for your help.

Your definitely supposed to be able to use the touchscreen when the keyboards out, That's how I use my phone most of the time. I think it's a hardware problem to me like some cable to the touchscreen got messed up so when you open up your keyboard it gets disconnected, but I really don't know could be wrong. Also, I don't see how reflashing hboot or the radio will fix it, as far as I know they don't affect the touchscreen at all.

As "Ianlikescake" Said its hardware not software. I work in a second hand phone shop & the most common problem with the G1 (Apart from people abusing this beautiful device) is a ribbon cable tears in the back when the screen has been opened & closed a lot.
Normally when it goes the touch screen goes completely but we have had one customer when the same thing happened to him as in your situation, We sent the phone off to be repaired & all they did was replace the cable
So re flashing the radio & hboot wont fix it, Sorry!

My phone has a problem not really similar but it still has to do with the screen. When i lock the phone and when I try to unlock it when the screen is down the screen doesn't turn on. But when I flip the screen up the screen turns on. Once I unlock the phone the screen works fine i flip it back down and it works untill it locks. So do you think it's a problem with the ribbon cable?

I think I have a similar issue. Whenever I have the keyboard closed, the screen will not turn on when you press the end-key. Only the LED lights will turn on. When you flip the keyboard out, the screen turns on and the phone is functional.
Over the next few weeks, I then realized that this only happens when the phone's keyboard is completely closed. If you leave the keyboard out 1cm or so (to the point where you can only see the spacebar), you can turn on the phone. Check to see if it works for you.

That used to work for me but now the problem got worse. Sometimes even when the keyboards out the screen doesn't turn on so I have to mess with the screen for a little bit till it works. Now I know it's the cable that's messed up. I think the reason it's like this is from repetitive flipping out the screen. I gotta be more careful next time if i can fix it.
