My sister cracked the touchscreen on her HD mini, and i ordered one from ebay.
After changing it, following the english google translated italian guide, the LCD screen just isn't showing any image. It does however still have the backlight..
Do i need to replace the LCD-screen as well? Any other options?
I've tried disassembling and reassembling again, but didn'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.

Hello just for information,
I broke my trinity screen and I baught a new screen to a HK seller and i replace it.
I had already flash the firmware (faman 3.6 full) before changing the screen.
So everything seems ok when I put the phone power on but As soon as I put the creen off, I am unable to put it on it appears every time in a complete white screen !!!! to have something on the screen I have to reboot the phone.
I just reflash the phone again with faman 3.6 and it's still the thame problem completly white after turn the screen off then on ...
I try also an official orange WM5 (gps active) and the screen work's well i try after to switch again in WM6 and it doest work :white screen again ...
Can every one help me ?
@ Rich: Check the 'How to dissamble the Trinity' thread. Are your sure that the LCD is broken ? Could also be just the digitizer (USD 8 at cnn.cn.shop).
If you succeed to dissamble the display you should be able to attach a new digitizer.
The only problem are the two black levers ... (one for the display cable, one for the digitizer).
Good luck

I cracked my Trinity screen with a bad golf swing. Then I bought a replacement screen on ebay, found a disasembly guide, took my trinity apart, replaced the screen, put everything back together, and it works fine! cost me 70 EUR to fix it.
do it following the disassembly guide - taking the trinity apart is rather complicated, you will not figure it out by yourself.
Sometimes I wonder what the engineers drink before designing such complex assemblies!
Greetings !
I am the proud owner of Qtek 9000 for sometime now.
Recently i was given a second unit, that at first look has a broken lcd.
The person who gave me the broken Qtek 9000 said that it had fallen off and then started to have the screen problem.
When powered on, the lcd displays blue and white lines during the width of the screen and the backlit does not come on.
If i plug the device to a Win XP machine, its get recognized and trying to sync
I assume the device must be working and this is an lcd only problem, although i have not synced it.
After reading around the forum and looking at the service manual on the wiki, i have disassembled the unit to see if any of the lcd connects got loose during the fall.
It seems that all connectors are in place, so my next task is to find if the lcd screen or lcd harness (cables) are broken.
Does anyone have any idea what i should replace ?
I have the same problem with red and white lines
Do you find what is wrong ???do you change the screen?
Welcome to forums
Try to do a hard reset (instructions on the Wiki), if not working perhaps you have to replace it, have a look on marketplace, one member is selling one
Good luck,
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.
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...
