HTC Touch HD Lcd screen displaying colored lines - Touch HD General

I recently gave my htc touch hd for LCD Glass replacement. Before that the LCD was working fine. After replacing the Glass the display din't work and the repair guy there is some problem with the LCD and I have to change it too. But after few days he said its working but the display is dull. Today I got my phone back and there are colored lines on the display. Everything is working fine just these light colored lines all over the display from the time i switch it on. I even hard reseted the phone. I din't send it to a authorised service centre. Can anybody tell me how to solve this. I would really appreciate it. Thank you

Not sure if it is going to help you but i will tell you anyway.
I have a Asus Laptop with vertical(you did not specify what kind of lines are) color lines on the lcd.On the forum s i read that this is an LCD failure(DEAD).
Since both are LCDs i think it could be the same problem.

Replaced touch screen doesn't work

Hi
I have a Qtek 9000 and recently I broked the display. As I had the service manual I thought I coud replace the display by myself. I bought a new LCD + touch screen on ebay and the replacing of the LCD was easy and went quite well. The lcd works fine but the touch screen don't. I cheked and clean all the contacts but couldn't make the touch screen work.
So I wrote de seller and we agree to send back de display and receive a new one that he will test bofore posting.
I placed this new display and the problem remais the same. The lcd works fine but the touch screen don't, so I think the problem could not be here.
I made a hard reset and even downgraded to the original ROM but the touch screen still not working.
Can anyone help me with this
Thanks
Have you tried the touchscreen side of things before re-asembling the casing?
I have had problems with the seal on the casing around the screen activating the touch screen permanently - so that it runs really slow (if at all) when using the keypad.
damn, did you get the touch screen to work at all?
which LCD + touch did you buy from ebay? hopefully we can avoid this seller and get something that works.
ever thought of buying the touch screen separately and putting that on?
Let us know how it goes.
whitemoo.
after disasembling/asembling device had the same ussie with touch,after a cup of hours using it.
armandoramos try to open,when UNI works,only a part of UNI with LCD(look page 21 in service manual-bottom picture,page 22 & page 23-middle picture),then try how works your touch.If it works-you just had pinch the LCD coaxial cable module.
i had a problem with my touch screen, i was lucky enough to find a second hand uni in a local market with a busted lcd but working TS.
i swopped over the TS and re-assembled my uni, one thing i did have to add was a tiny piece of foam between the ribbon cable assembly and the case, this was to push the two ribbon cable sections (TS and LCD) together, for a better connection, relying on the sticky bits alone was not enough.
hope this helps.

Dropped my Wizard - White screen

Hi to everyone.
I dropped my wizard and lcd broke so I bought a new one and put it on. The problem is that although it takes phone calls and it syncs to pc, the screen is always white with nothing written..only a white screen. I do not know whether another problem occured besides the broken lcd. I tried to disassemble and reassemble it again but with no success. Any help please?
Hi, If my understanding is correct there are 2 versions of LCD for the Wizard. Are you sure that you have the right one? I'm sorry that I am unable to offer any further advice except to say that if the phone 'phones' and 'syncs' the basics must be working. Also the white screen means that the backlight is working - the problem is the LCD drive. Perhaps worth checking with your replacement supplier that they sent you the correct part?
Good luck!

Help screen replacement problem!!!!

Hi guys, i followed all the indictaions on the official videos but i think i broke something! I had an HTC hd2 with a broken digitilizer but the screen worked fine. I bought a screen+digitilzer combo and replaced it but it didnt work.
The screen does not show anything (black screen) but the backlight of it is on!
I tought maybe was a problem of that lcd so i tested the original screen (that was working) and it does the same.
What could be the problem??
Please i need help
come onn, anyone ?
please guys, anyone ??
Sounds like a defective lcd to me. I'd try an RMA asap on getting another unit before your DOA warranty (if the lcd has one) runs out.
it's not the LCD. I had a working LCD but a defective digitizer, i bought the lcd+digitizer replacement and now both screens do the same , just the backlight is on. And before i change the screens the original lcd was working fine.
Could it be because the LCD is not correctly pasted into the chassis ? i really don't know what could it be the problem. The lcd is correctly connected to the mainboard. What could i broke in the process?
Thanks connexion2005 for the help anyways, is nice to see someone finally answered hehe!

If you were not really gental with the internal parts of the phone, more presisly the ribbons that connect each part to the main board you could have cause micro cracks in the copper strips of the ribbons. Look at the closely with a magnifying. glass if possible.
today i was able to sync it literally with no idea of what i was touching. I also figured that the digitizer works , i was able it dial some numbers. The phone appears to work.
So, Backlight is on, Touch (digitizer) also works, but not showing anything on the LCD.
Could it be a mainboard problem ?? I'm trying to use logic because i don't know anything about cellphones and how do they work in terms of components.
Could it be the ribbon ? I dont think so, i have two screens and both of them do the same (backlight on but not showing anything).
I'm clueless!
Don`t panic. Calm down, watch a demolution tuturial. You probably miss smt. Good luck
But it could be a ribbon...

[Q] HTC Trophy LCD problems, please help!

Ok, I recently fell on my HTC Trophy(Verizon Version), cracking my screen. Before that happened I had a weird LCD problem that came out of nowhere. I replaced both the touch digitizer and LCD screen successfully and turned it on. It worked perfectly. No screen defects ect. Then I later turned it on and the same problem happened! Here are some pics to show you. Do I need A new LCD (oh god) or can I fix it? any answers will be much appreciated. Also, the auto thread search thing is wonderful, great idea!
EDIT:I can't see the spots when the LCD is off.
When I was doing a laptop LCD replacement screen, I had accidentally left a bubble and was so annoyed that it would not display where the bubbles were.
However after 2 weeks the bubbles just disappeared and the laptop's LCD screen was working correctly.
You might want to wait a little longer and see if the heat will evaporate it?
(Good luck)
