Hello,
Today, the screen suddenly started looking like the attached photos.
It's like the tablet fell on the floor or something, but nothing like that happened.
Is it a broken (i.e. hardware) screen, or can it be something else?
Thanks.
In my point of view this is an hardware related problem, probably the LCD is damaged, use the warranty and send it for repair or replace.
Today the tablet returned from the service, they changed the front cover and everything works well again.

So, about 2 weeks ago, I got my HD2 off of Craigslist with a cracked screen. It worked perfectly fine with the exception of the hardly noticeable cracks. I knew I could get the replacement digitizer/screen for $40-80. I got my screen in the mail yesterday and, following the "YouTube" video tutorial found on this site, I......ugh.... replaced the screen....................I SCREWED UP BIG TIME!
First, I broke the ribbon cable for the Side "Volume Up/Down" buttons. Then, I broke the ribbon cable for the "soft keys." Ah, crap, but oh well. I figured I could use the touch screen for pretty much everything i needed to do. Well, while prying the cracked digitizer screen from the LCD, I went a bit too deep & peeled the tinted film off of the LCD. I thought nothing of it at the time. I'd already done enough damage. So the display would be a bit brighter than normal oh well.......WRONG! I put the phone back together and once I get it to power up, all I get is a white screen. I thought I missed something. So I disassemble & check 3 more times. Still a white screen.
Well, after all of this, the new digitizer/screen doesn't want to stay in place very well. So, being pissed off and curious, I pull it out and away and notice in the backside reflection of the digitizer that I can slightly make out the phone display. So, apparently the "Tinted Film" that I accidentally peeled off of the LCD makes images visible on the phone screen. I kind of damaged this film when peeling it off. Therefore, I am unable to put it back on. Does anyone know of a simple fix without replacing the LCD?
SORRY FOR THE "SHORT STORY LONG."
I was brainstorming and thought that maybe the film was polarized. So, I grabbed my sunglasses, which are polarized, and wearing them, I can faintly see the display. Anyone think maybe polarized window tint might fix my problem?
Hey man I have some electronic devices that need repair, can I send them to you to fix them?
SURE!
You can pay me in HD2 parts.
Sir i can only say 1 thing. search ebay and replace everything you damaged. only that way you will get your hd2 in perfect state.

I'd go one step further and say bin it and get a new one!
You sound just like me. That is why I never try things like that anymore. Hope it gets sorted but might be better looking for a used one.
I've got it functioning...
I found the film that I ripped off, put it over the screen and........I CAN SEE! However, the top half has lines through it. So, I must've damaged the LCD. The good news is that my phone is useable again. I just have to do everything via the touch screen and can't let the screen hibernate unless I have my charger close by. I'm just gonna keep my eye out for a cheap busted phone and eventually have a 100% phone again...
I sympathize with you. I broke HD2 while I was trying to check for loose WiFi card cable(cuz i was getting weak WiFi signals). The cable turned out to be fine but the external speaker stopped working. I opened it up again and adjusted some parts and it just got worse. the HD2 didn't power on at all. I tried fixing it but to no avail. I ended up sending the HD2 to a repair shop and was charged $170 for the repair. the repair guy said i messed up the power IC and the connector for the external speaker and he had to replace the power IC and resolder the connector.
I think I'm gonna stop trying to open up expensive phones. i was stupid thinking that since I have successfully replaced digitizer for my previous Palm T3, E2 and T5, opening up HD2 wouldn't be a problem. Should have known HD2 components are really fragile...

The best topic ever Thanks, dude!
Had this phone about 3 weeks now and all of a sudden whenever I make a phone call the screen just goes black until I take the battery out or the other person hangs up. Is there a way to tweak the proximity sensor settings like on the omnia 7 etc?
I'm having the exact same issue. I've only had my Titan for about four days now.
I just firmly pressed on the front and back of the device as if to correctly place put the back case on. This works for a while and 'randomly' quits. I have yet to figure this one out.
I've not had this problem but you could try the other rom from here. I had the .02 but changed it to .06

Not had any problems with my titan since I flashed it.

Thanks! I'm gonna' try flashing this. HOPEFULLY, it will work.
I'll post back with my result.
Nothing! Tried the ROM update but no luck. Still having the same problem.
Dam thats a shame, could be a hardware issue
same issue on mine. Had it 2 weeks and it just started going black when calls come in or go out. I have a replacement on the way, I hope its an isolated issue...
Same here. Had mine for 2 months and now I have this issue.
Any ideas on how to solve this yet?
same here...
any hints if its a hardware issue or a software issue
mine also worked a wile and then stopped working...
You may already have tried or been aware of this so forgive my two penneth worth, When I had my HD2 It was the screen protector that tripped out the light sensor and kept the screen dark etc, May be worth a try if you have one fitted as it did the trick.
HTC Titan Prox Sensor
I do hardware repairs on phones, and currently having this issue with an HTC Titan. It seems very likely to be a hardware issue. The back cover feels loose and sloppy in my opinion, yet seems to play a role in properly grounding some of the auxiliary sensors. I'm considering trying to order the part, but it seems to be impossible to find except from a used phone. The proximity sensor is on a small chipboard that snaps directly into a connector on the motherboard. The solution of pressing the screen and back housing together makes sense if that proximity sensor isn't making a good connection to the board (or if it isn't grounding properly).
In my experience, I'd say this phone is a pain in the butt to diagnose and repair.
Exact same problem! Was thinking about doing a hard reset, but it seems like that won't fix it. I bought my Titan used, and maybe that's why it was on eBay. Phone works perfectly otherwise, absolutely love it. They sell new covers on Amazon, maybe that will fix it, by applying more pressure on the proximity sensor. Wish there was a simple fix.
I have this issue as well. I have found out that when you press the upper right corner of the screen the display comes back on but as soon as you let go it goes black again.
Also if you slightly open the back cover from the bottom the display comes back on as well but you lose signal because the antenna is disconnected. When you close the back cover the display goes black again.
It happens with outgoing and incoming calls.
This is really annoying and if I would very much like to know if it's a hardware or software issue.

Update:
I think I've found a solution.
I believe the the proximity sensor is in the narrow gap above the screen.
I opened the back cover and I slightly scratched the two contacts on the top of the back cover with my fingernail.
My Titan somehow is now working again and when I move my finger close to the narrow gap the display goes black.
I therefore think it's just a matter of a dodgy contact between the proximity sensor and the back cover.
I think I'll order a new back cover fom eBay to see if this improves things. My back cover is damaged anyway.
Possible Solution
i hope this is the solution cuz im tired of messing with this phone (we lost money trying to repair this phone, ie. negative profit, cuz the lcd and digitizer are fused together and it took forever for the parts to be available online). BIG Thanks to everyone who contributed to this forum thread.
The problem is almost certainly hardware and related to the back cover. good news means that it should cost nothing to fix. *warning* as always, you could break your phone if you arent careful. I havent tested this solution but i will tomorrow. On the motherboard are "metal brushes". That means springy metal contacts that are meant to make contacts between parts that arent closely touching. look at the back cover and find those contact plates, then look on the board for the corresponding brushes. gently pull those brushes up away from the motherboard to make them extend further, and see if you can get the back cover to fit more snugly on the phone. be careful with those brushes, metal can only be bent so far before breaking and then youll have to do board-level soldering (pain in the butt, not easy). if you can ensure proper contact between the back cover and the motherboard, then you shouldnt have any more issues with the proximity sensor.
this is my educated guess, let me know if you have any luck.
PS! been using iphone 4 for like a month, and the more i use it the more i hate it. i typed this up with iphone 4. so much hardware power with so little control. id recommend iphone to anyone who doesnt like technology. iOS is a POS
Called HTC and I'm still under warranty. I'm going to be sending in the phone for repairs tomorrow for this problem, we'll see what happens. They said it'd take 14 days to get my phone back.

Hi Flavio, have you bought a new cover? Has it fixed your problem?
Have the same problem with the sensor, i´ve tried other roms to, but still the same problem. i dont think, that this problem is a hardware issue of the proximity sensor, becaue sometimes it works sometimes note... very curious...
I just got a new Titan with the same problem. I took the phone to HTC repair center and the repair status on their website shows is that its been fixed, meaning I should get it back early next week. I will report here about the description what they did to it.
And this is clearly a HW issue. Taking off the back cover seems to affect little, but not 100% remove the problem.
Had this issue. When I sent it off to HTC they replaced the screen together with the dusty FFC issue
I had a similar problem that was fixed by turning of "Automatically adjust" in the brightness setting.
I just recently purchased a Samsung Galaxy S2 from eBay, the seller stated that the LCD screen was "very dark" and not quite working right. When I received the phone it was far more then "very dark", half of the screen looks as if the LCD is leaking out or has been broken? The digitizer is mint and works and the phone its self is in AMAZING shape. NO scratches or chips or anything. It honestly looks brand new. I even tested the battery for usage and its showing up that this battery IS indeed brand new. Like I said it is mint so there is no possible way this phone was dropped. My first guess was a ROM issue, but I just noticed you can see the screen defect without the phone even being turned on. So what I am thinking is water damage. I read all over online about people having problems with there screens going black, this might also be the case. If it is water damage, does anyone know EXACT locations of indicators on the phone? I looked in the battery compartment and found nothing what so ever. I want to sell this thing today, (just received it in the mail) I need the cash so I was hoping someone would be able to point me in the right direction?? I uploaded photos below, the second one is with the phone turned off, the reflection is from my computer. For reference, it is the Samsung Galaxy SII 19100, with Bell Canada. Thanks in advanced!
I'm no expert but does not look like something you can fix yourself I'm afraid.
Send it back I say.
Sent from my GT-N7000 using XDA App
send it back to whoever sold it
you kinda got scammed there, imho
See Im trying to figure out if the LCD was broken by physical damage or if this has happened before to people, because if its a manufacturing issue I can just send it back to Samsung and they will fix it no problem as long as this was caused on their part. If it WAS broken by the ebay seller, I might be better off buying a new lcd and installing it myself. I only paid $200CAD so it would be worth keeping if all thats wrong is the LCD. But like I said I would rather Samsung do it, lol its free.

Scratch that, the LCD is almost $200. Not worth buying and fixing. But does anyone know if this could be classified as a manufacturing issue? I can just send it in if it is?
anybody at all?? I just want to confirm that this could be a manufacturing issue, theres no water damage and the screen is not cracked from a drop any ideas would be awesome. I might just try to send it in to Samsung just to see what happens.
Hi, I'm new here and sorry to bother ya all, but I have a problem that I have discovered lately with my Prime. One section of the touch screen seemed to be unresponsive to touch, it's only about 1cm from the left bezel when viewed in landscape mode, for some reason it just won't respond to touch anymore, is this a software problem or something's wrong with the hardware? I'm very reluctant to send it for repairs because I needed it. Would appreciate any kind of help, my prime is running on Android 4.1.1, stock Asus software. Thanks
Probably hardware. Try a factory reset but I doubt it would work. ASUS will replace the screen for you under warranty. The screens are very bad quality. Mine has been replaced twice in RMA. Also a new motherboard, casing, 2x batteries, camera, wifi pcb's. Pretty much a new device.
Hey guys,
Just a quick question. I've got one of the first release Huawei mate 10 pros. Dropped it from about a hip height onto tile, no visible crack or damage to the exterior or screen but since then I haven't been able to use the touch screen.
I get a bit of the slide from the bottom and everything else works but I can't actually use the screen because I can't swipe patterns or type in, it's basically a dead screen, but if the whole screen was out of commission I wouldn't get any slide action at all.
Need the phone for work, any quick responses with experience in the area would be much appreciated.
Cheers.
I'd say its definitely hardware related, as in broken.
You'd have to get it replaced.
Even if you get no cracks the digitizer can be broken.
Aw man, I was really hoping there was some sort of software bug that was causing this, well I'll stay hopeful that this has happened to someone else until I have to claim the warranty

It has happened to me (sort of), but I got a crack and the touch screen below the crack didn't work at all, top part worked fine. Or vice versa, can't remember but one part was still working. This was on a Samsung though.
And on an iPhone the screen completely shattered, but touch was working fine. So the digitizer wasn't hurt there, but it still required a touch + digitizer replacement as they are glued together.
If there's no crack, then it might also be a loose connector.But even so, you would need technical assistance.
If the warranty is still valid and there are no visible signs or scratches from that fall, maybe Huawei will repair it for free.
Yeah I'll be following it up with optus because it's still on a plan. I shattered and bent my mate 9 and as soon as there was a crack the digitizer went. Might as well use the warranty because if I open it up myself it'll void it for future use.
Thanks for your input guys.
