Nike Full Working but "Black screen" - Touch Dual, MDA Touch Plus ROM Development

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!

HD2 No Screen

Qeustion
My HD screen is off, and i cant seem to get it on again.
I just was working on it 1hour ago, took it out of my pocket and see that i have no screen.
Rebooted the phone, but no succes .. i see the screen turning on, but it light-gray (backlight) but no actual info/colors etc, also tryd a soft reset, no succes.
I have the Energy ROM Com5 build from 8July with the new 2.12 radio rom.
Could it be that in some way the screen died?
Hope someone can help me, im @ work now so i cant connect it with the PC.
When im home im planning to reflash the device ..
Thanks!
Weird
I just pressed a button and the screen turned on, and the colours/info just slowely fade away ... weird.
Could it be that the touchscreen is not oke anymore?
Or could it be a problem in the radio/rom i use? (and therefore a reflash could fix this?)
Hope its a easy sollution, otherwise ill be flashing it to stock and get it fixed by HTC.
Very very strange.
It seems to work again.
Anyone think i should reflash it to stock and try get a new one?
Are these signs of a screen going defect?
I dont know, first phone for me with touchscreen.
I would suspect a faulty screen, if it is still within warranty i would deffinately get a new one, however yes, try going back to stock first, see if it helps, it may be just a bad flash.
screen problem
I've had this and similar problems with my HD2, now on the 5th replacement from HTC in just 6 months of owning the phone. I also had the same problem on my HTC HD previously. Press the power key and just the buttons at the bottom light up but no response from the screen. Also had exactly the same problem your experiencing where you can faintly see the screen but not lit up. Flash it to stock rom and return to HTC for repair.
BEWARE!!! take some pics with date stamps of your handset before returning. They sent me 3 handsets all with the glass front panel not fitted correctly. Check the return handset carefully, you should be able to feel a lip between the casing and the screen as the screen is set a fraction lower than the casing. THis should be uniform all around. They tried telling me that i had damaged it myself despite calling them as soon as the handset had been delivered back to me.

That's 'sleep of death', which affects loads of htc devices.
Oke i will stock it soon and return for repair.
I think its idd a screen problem, cause when the screen isnt functioning anymore, and when i put my ear on the glass, i hear a little squishing sound, like air is escaping .. it doesnt do that when the screen shows info/colour.

[Q] Inverted response from digitizer

Hi,
I've tried a number of firmwares Europe/Asian/T-Mobile and my local Telstra Rom. But no success.
I replaced my smashed digitizer and LCD the other day, however everything works great, the touch response is inverted - Left to Right. All touches on the left side are responding as if I'm touching the right side of the screen. Everything in the middle is fine obviously but from there it's mirrored.
It's quite possible that because the digitizer was bought from the USA and its in a Telstra (T8697) phone, it's somehow incompatible.
By bootloader is stating the TOUCH is C1(v66)
Does anyone think they may have a solution to this? a Registry edit or some kind of Screen calibration?
Cheers for any help.
BTW - The digitizer capacitive buttons are also mirrored i.e. Back is Search and Search is Back.
This digitizer also has a circle around the Windows (Start) button. My old screen didn't have this..
same problem
Hi gauge41,
I have the same problem :crying:. Do you have a solution ?
I bought my touchscreen on uk by ebay.

All updates have been done through Zune software without changes.
Best regards.

I've read somewhere, that there are two modifications of a touchscreen for mozart and they are not compatible, so if your previous digitizer didn't have a circle around windows button, but new one does, mirrored input is definitely because of that. Haven't heard of any registry tweaks to fix that, and I don't think you can fix it by installing different rom. You should probably get a compatible digitizer replacement or try installing different touch screen drivers.

[Q] Display broken SIII screen on moniter

Alright, my problem is I have an SIII with broken glass, a broken digitizer, and a broken LCD. It's my old phone as I had to buy a new one due to these issues. Ended up getting the HTC One. Eitherway, I can't use the screen at all yet I can turn it on and everything. Turned it on today, and since it's on a seperate number than my One, I got tons of notifications the second I turned it on, plus, I need the screen for a few other things. My question is, is there anyway I can display the screen on my laptop through USB running on Ubuntu without the use of my phone screen? Also if anyone knows how, I do ask for super detailed instructions as I suck with Linux now. (Old HD died due to Windows sucking.)
Thanks in advance.

[Q] [HELP] Xperia Mini Pro Broken Screen

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!!!

Moto e dead spots on touch screen

Hey guys, a friend of mine give me his moto e cause he had soft bricked it. Reading through the forum I could reinstall the firmware (4.4.4 latam) and now it's working fine, but there are 5 spot in a vertical line that doesn't register my touches, these spots are aligned in the middle of the screen, one is at the y position of the keyboard, and the others are separated 1cm each other (1 is under the y and the other 3 are above). Could this be a software related problem or I just have to replace the touchscreen? (I've tried factory reset two times but I've not reflashed the firm again) thanks in advance and sorry about my English.
First take a try with Screen tester app die playstore, and change rom once, if didn't helped, you can replace screen assembly at low cost on local markets.
Well, i've reflashed the stock 4.4.4 firmware and it's still the same, i guess i'll have to replace the touchscreen. I dont know how the touchscreen works in this phone but it's a little strange that certain isolated areas in the middle of the screen doesnt work..

I had the exact same problem. I had 4 such huge spots on the left side of the screen where touch didn't work. ROM reflashes don't help. Yeah it's really strange. First I thought it might be cuz of water spilled over the screen but later on found out that the display assembly is completely sealed and water can't get in. Yeah it's really strange how display suddenly stopped working that way..even touches of local phones don't get magically spoiled like this, dunno what's up with moto. I got it replaced from local market for 1300. I would say the quality of the display, touch, brightness, contrast, everything is same as that of the original display. The only thing I suspect is that the glass is not gorilla I guess.
