Hi, i received HTC TYTN from customer. On startup lcd will display, then suddenly goes black. Phone starts completely. I upgraded rom, but still the same. On boot mode lcd allso display. Only goes black on startup. Is this a
hardware or software problem?
Thanks
Try a a HR and see what happens or try to downgrade to another rom. If problem persists it may be hardware but if it is displaying on startup it sounds more likely software. If you have other software installed you may need to eliminate problem by installing one by one until you find the problem app.
Cheers...

Hello I have an HTC Touch Dual (Nike) running Orange UK rom. The phone is in full working order, wich i confirmed with the mymobiler software. The only problem is that the screen is completely black, well you can see some light. My question is how do you know if it is an LCD problem or a flex cable problem without trying on another device.
If you didnt drop device, i don't see any reason why LCD screen will die, it's kinda strong thing.
Well i replaced the screen, and the problem continues!
Please help!
Since yesterday, after plug off from loading, my HD2 (German t-mobile ROM 1.77, Radio 2.07) doesn't switch of screen. In the past week, I haven't changed anything or installed any apps.
By pressing 'off' key, screen becomes black and will be revoked with screen lock after few seconds. When screen light gets low after predfined time, it will come back will full light after few seconds.
I've tried hard reset, installed stock ROM from t-mobile (include radio ROM) - nothing changed.
Does anyone can help?

I've seen this issue periodically here on the boards. From what I've read from the users who experience this issue, it is likely to be hardware related. One way to test this is to turn off the screen when the device is plugged in (charging)? If the screen will stay off when plugged in then I have some bad news.
The only solution I have seen is to send the device in to HTC for repair. Sorry.
I believe it has something to do with the micro usb being defective.
Hopefully someone will correct me if I'm wrong.
Many THX, the device is within warranty and I will request for repair.
this sounds like the "car kit mode" hardware issue.

Look at the end of the thread for the reason it is happening, and you will need to have it repaired or replaced.
Device has been repaired/changed by t-mobile Germany without any reservations within 48 hours.
Hello! So my Xperia Mini pro has been broken, it doesn't show any image anymore, I think there is a problem with the screen but I want a confirmation or recommendation to find out what the problem is.
First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
Thanks!
Hey there.
Based on my experience, yes, your problem is most likey a flex ribbon issue. Your flex has been ripping apart lately, causing many of its wires to break. This can cause a lot of unpredictable problems, such as a misbeheaving notification LED, inactive ambient light sensor, or "dead" display/touch digitizer. Your problems have gotten worse over time, which is clearly a symptom of a broken flex.
You phone is no longer booting up to android because the kernel no longer detects a proper "response" from the display driver and halts the bootup. This is why you can feel the phone vibrating when pressing the power button, but nothing else happens. Your screen assembly is fine, I can assure you that, unless your glass is broken, of course.
Here's one hell of a good teardown guide: http://www.ifixit.com/Teardown/Sony+Ericsson+Xperia+Mini+Pro+SK17i+Teardown/7275
I used that very same guide when I repaired my own xmp. I regret messing with my screen assembly because I destroyed it and had to buy a new one, which is costly
Thank You so much for the advice ! Now I'll try to repair it, It doesn't seem too difficult. Thank You Again!!!
Hey Guys,
I am having a big problem with my device. The touch is not working. I have been flashing various roms on my phone and after playing with many roms, i finally flashed stock rom into my phone and flashed a stock ics based rom. Everything was working fine until one day my touch was not working well. I switched off the phone and turned it on and the touch was right back on. Again, things were smooth until this issue happened quite frequently. The problem was solved after turning off the phone and powering it off. After some time, the problem again started to come. At this point, the touch was not working COMPLETELY.
I was scared and immedaitly flashed the stock rom. During the initial boot, everything was working fine. But, when i locked the screen and tried to use the phone after some time, the same problem occured again.
So friends, my question is, Is this a software related problem or a hardware related problem. If this is a h/w related problem, is there any point in touch working during some time and not working later? ( Now, touch stopeed working completely). Will any tutorial on this forum about bricked touchscreen (after flashing wrong rom, which i am sure i didn't) will help me solve this problem?
I am awaiting for your valued input as this is the phone that i use for all my communication needs.
Kindly help me
Thanks
Well, if stock didn't solve it, there's a chance it's a hw issue. If you look closely, "touchscreen brick" guides are meant for the mini and the lww (touch digitizer separated from display), not the mini pro (touch digitizer and display as one assembly).
And yes, there are situations where your touch digitizer might cease to function for a few seconds then respond after a while, and sometimes it stops working completely after the next reboot (or forever). It happened to me with a deffective replacement part.

Thanks for your reply.......
I guess it is indeed an hardware issue. My phone used to reboot when i slide my keyboard out fast. The screen gets dimmed out and the phone immediatly restarts. Last few days before the problem worsened it was overheating also.
Can you suggest me which hardware part i should change to rectify the touch issue? Awaiting for your reply
Thanks a lot
Ok your problem seems to be worse than expected. A faulty touchscreen shouldn't cause sudden reboots. I'd say it's a flex ribbon issue.
Try to get a replacement flex ribbon and test it extensively before installing it on your phone. Replacing the flex might be enough to solve all of your problems. If any of the problems persist with a new flex, you'll need a new screen assembly (quite expensive at 35~50 bucks).
Hello everyone.
I have a problem with my smartphone Sony Xperia Z2. I dropped it and the display broke. I bought a new display. When I connect he went crazy. He began to open the application, clicking like 10 fingers working on it simultaneously. Because I thought that the display is faulty, I've exchanged for a new one. But now even bigger problem. When I turn on him, he does not show anything on the screen except the backlight. Do you know what the problem is and whether anyone had a similar problem? So, when the smartphone turns on, lights up only the backlight but nothing on the screen showing a. At first, there is a lot of vertical lines on display, and once he just fade out, and from that moment display is blank only backlight working. I try to update software, but nothing change. Restarting, and turning off also nothing.
Please help me solve this, for me very frustrating problem.
anyone?

Did you ever get this resolved?
I had this issue after a screen replacement for a shattered screen. I was sure I had damaged something in the process (ribbon flex cable, motherboard, etc). Turns out the replacement screen was faulty. A new working screen solved the issue.
