Hi all, this is my first post on this forum but I've been reading for a while to educate myself.
I've got a Herm200 that I've been trying to troubleshoot but to no avail. I'm fairly certain that it has a hardware problem but I haven't been able to isolate anything.
Here's whats happening:
Occasionally the screen will come out of stand-by all white. This will also happen randomly if i touch the screen to perform a command. While the screen is operating, sometimes the buttons on the face will stop working, however the buttons across both sides will continue working just fine.
When the screen turns all white a soft, hard, or stand-by cycle will not always bring it back to life. The fact that the hard reset wont always fix the problem makes me think it's a hardware issue since the phone will boot-up with the the all-white screen.
This is incredibly frustrating especially since HTC wont accept any warranty claims in the USA on the Tytn.
At first I thought this might be a problem with the ribon connection between the screen and the base but i haven't been able to confirm or discount anything at this point. I have yet to find a way to consistently reproduce or rectify the problem so it's very hard to troubleshoot.
I pretty much have to take a second phone with me everywhere right now just incase i need to make a call. Please help! Has anyone ever encountered such a problem?
Thank you in advance!

Hi. This sounds very similar to a problem that I experienced with a HERMES100. I bought the phone off someone on Ebay recently - someone had obviously scrambled the radio on it. I re-flashed it, and it sprang to life. However, after a couple of days, I experienced a problem where occasionally the LCD would stop refreshing, all the pixels faded away leaving only a white screen. Under these circumstances, some of the buttons on the phone stopped working. Turning phone on/off sometimes cured the problem, or it would require the occasional hard reset. This would happen once or twice a day and I suspect thats why someone tried to re-flash the phone.
In the end, out of curiosity I took the entire phone apart, put it all back together again and now there are no more problems!! Totally fixed!
My suspicion is that it was one of the ribbon cable push connectors on the mainboard - possibly not seated properly, or a bit of dirt contaminating the connection. Obviously when I took the phone apart I must have re-seated it.
If you are planning to take your phone apart, please exercise considerable care because some of the parts are very small and easily damaged. I would recommend buying a proper kit to take it apart. I bought mine for about £5 off ebay. Particularly useful are the plastic spoon "wedges" used to gently prise open the case after removing the screens. Don't use a screwdriver - you will scratch the case.
Good luck.
wow... that sounds like exactly what's going on here, I actually even tried to disassemble it lastnight but didnt have the right driver set. thank you for the advice!
I'll look for one of those sets but what would you search for if i needed to find it?
Thanks again, I just got a set off of Ebay. Hopefully it'll be here next week
With any luck it'll be a connection issue.
I have had the exact same problem. Because I got the Tytn through work I made our IT department handle the issue and I am currently waiting for a replacement and to find out what happened.
Yep, it looks like the problems the OP is having are very similar to the problems we've been having over in this thread:
http://forum.xda-developers.com/showthread.php?t=291027
I'm beginning to think it's a hardware problem as well but not entirely sure.
People in the above thread mentioned that using the scroll wheel a while then moving back to use the D pad fixed the problem (very briefly in my case.) Once I use the center D pad button again it locks the hardware buttons under the screen until I make my device sleep and resume.
Somtimes rather than making all the front hardware buttons unresponsive the issue is that once I use the Down Dpad button I can't use the up button. Pressing up will make it go down, as will pressing down (at least that's working ).
Regarding the white screen - this sometimes also occurs. I can force it to white screen by putting a little pressure on the silver panel surrounding the top, right and bottom of the screen (I have an imate jasjam). Randomly when there's no pressure on the rim and I wake it out of standby, it has a white screen that can only be fixed by turning the screen off and on again.
Finally, the LED indicator seems screwy. Sometimes it never flashes. Other times it flashes sporadically (uneven intervals - we're talking maybe a minute between one flash then seconds before another). When I charge it sometimes the LED doesn't come on but nevertheless it charges. Sometimes if the LED is on it never turns green to indicate a full charge. Yet other times it comes on orange, turns green, then never switches off!
Is it possible that
a) The hardware button problems.
b) The white screen problem.
c) The LED problem.
are all related to some kind of connection going loose? Why would the hardware button problem be temporarily fixable with use of the scroll wheel if this were the case?
The other thread has fallen silent. I'm hoping that some of the gurus in here can offer some input here, even if they don't know the answer but can formulate an opinion. I know very little about these devices.
Thanks in advance guys!
PS - don't really know if I should start another thread, I've posted here as it seems like very much the same issue.
Anybody any idea? advice?
I had a similar problem with my HERM100. I didn't mess around with it too much, I just had Cingular replace it out of warranty exchange (thank god those original ROMs are on the wiki ). I did notice however that after doing a master reset, the screen would function again although I haven't messed around with it too much. I got so frustrated with removing the battery for 5 minutes and STILL powering on with a white screen that I just threw it in my back seat until the new one arrived.
I don't have these screen issues. I only have hardware button problems. It's so damn frustrating! I already own a replacement.
I just received a call from my girlfriend. I wasn't able to answer the phone with the buttons, only with a screentap. I also wasn't able to close the call with the hardware button. Since the side buttons work, I went to settings -> phone, closed it, and there we go. The hardware buttons worked again.
Why the heck is this? I truly hope for some wizz out there with some advice, since HTC would only tell me to send it back after replacing it with a new TyTN with same issues.
Regards,
DM.
Anyone anyone?
HELP!!!!

This is my first post as I've so far managed to cure all my issues from just reading the forum. However, I am now having a similar problem with the white screen.
I have a cingular 8525. It fell and the following day the call and end buttons remained lit and wouldn't turn off and they also wouldn't work.
I soft reset, nothing, I then removed the battery and when I turned it back on, there was a white screen and the buttons below still don't work.
I have read the other posts on this issue, but I need help on exactly what kit to buy to reconnect the screen cable and instructions on how to do it as I've never taken apart a phone before, although I have dabbled with other electronic devices.
Your help would be much appreciated, as I am in Jamaica and there are no technicians here who I trust to help.
Thanks in advance.
Below are links to 2 kits I'm thinking of getting. Is either one better than the other?

Both kits look ok. PDA one tells you a little more but the basics appear to be in both.
I'm curious though you soft reset and took the battery out, but have you done a HARD reset? I would always try this first before dismantling.
Mike
In my case, they also are always lit up when the screen is also active.
And no matter what ROM version, they occasionally stop responding. Side buttons keep working.

Thanks for the response.
I couldn't do a hard reset because the buttons weren't working.
I have made some progress with the phone now. Found a tech guy who looked at it for me. The white screen is gone, but the buttons still stop working from time to time.
All the connections seem ok.
Is there anything else that could cause the buttons to malfunction?

Nothing obvious.
Have you got applications installed that you have loaded - could be one thats playing up.
Have you now been able to do a hard reset?
If taking device apart and reassembling improved things it does suggest hardware though and might be worth double checking all those multi-connector blocks for good connections - i.e. take them out and in a few times to ensure any oxidation on contacts is removed.

If it wouldn't be a software issue, why is it, in my case, instantly resolved when going to settings -> phone with the side buttons?
i had this problem i took it to a guy who fixed the problem he said it was a very small tear in the flex cable which causes this white screen every now ant then and the buton problem , sorry to say its the cable problem and u need a very capable person to fix it or replace it with a new one . its very common problem baised on the guy who fixed it .

Exactly what is happening to me, no white screen issues, just screen taps and answering calls, I also have another problem where the PDA will not allow me to open anything, be it the start menu or contacts, it will open and quickly close again. I have had mine swapped through Telstra in Sydney, it worked fine for a while and then the same crap again. These problems started before I even touched the OS, so it must be a build problem. Maybe we should write a joint letter to HTC letting them know that there is a serious problem with their machine.
I have had the same problem, got my Tytn through work so we sent it back to the company that supplied it to us. Got it back yesterday and they had replaced the "switchboard". Not sure what it is but there was the problem. Had white screen and buttons not working.
Do I blame the onboard video or the LCD itself for this problem? I've taken the phone apart and re-seated the motherboard connections, which was no help. If I connect using EveryWAN the phone appears to be working fine, in fact I flashed the T-Mobile ROM and than the Button ROM thinking it was a IPL/SPL issue. Even if I try to start in boot loader mode the screen still looks the same.
Just trying to decide If I need to replace the motherboard or the LCD.
Thanks,
Bump back to the top!
Screen seems intact without any damage visible, no cracks or out?
Had this problem once with my old Universal, was the colour transfer wires that were loose, but pretty sure the Uni is totally different to our wizards.
Prehaps open her up and see if theres anything thats loose prehaps.
I had it opened and re-seated both the connecting cables, but no luck.
Ive had this problem with my wizard .. i couldnt find a solution. tho i didnt really try very hard. Basicaly just picked up another one on ebay for like £30 seemed cheaper than spending the time and effort fixing it. I think mine got progressivly worse. It used to do it occasionaly and now just it as soon as its switched on
i have a same sort of problem...
left of the screen fills with lines and the whole screen fades to white.
turning on and of the screen via power button takes it back to normal but then it happens again.
noticed it only happen in portrait so i have to set it to landscape all the time
for some rom and spl's it happens just a few times a day and others i cant use it in portrait.
If i find a solution it might be working for you to
Fading white screen of death
Could be the battery. Have you tried a new battery?
Solved.
The LCD itself was bad.
Has anyone else found that occasionally the screen starts going mad? I will unlock the phone and suddenly it starts going into various menu options, brings up a browser or brings up widget settings. It's as if there is an invisible finger using the screen, although it's so fast it's as if there is a buffer of actions.
I'm not sure what causes it, but a colleague has a Samsung Galaxy and reckons he gets it when moisture gets on the screen. My screen has never been wet or near anything wet.
Additionally, I've noticed it was happening just now when I was charging the phone via USB. When I unplugged it the behaviour stopped.
Anyone else?

Never had that before , maybe a application you installed that is acting wierd?
I had a application installed that just drained my batt like hell.
I also reboot the phone after heavy duty, meaning using the explorer , games, ....
me too!
I'm getting the same problem at the moment. It takes me about 5 attempts to unlock the screen. Once I'm in, sometimes it responds to my touch, sometimes it doesn't, other times it just does random stuff. It's making the phone totally unusable .
I got the phone on Monday (3 days ago) this is the first time it happened. I'm sat in a cafe atm and it's quite humid in here; if it's a problem with moisture could the humidity explain it?
I once had a similar problem with an ipod touch after it had been in a bag with a leaking water bottle. It went OK by itself after a few hours.
Anybody else got any thoughts?
Thanks
Damian.
The thing that I had to get used to was gripping the phone properly. The lower right quarter of my right hand is a bit chubby, so when I gripped the phone my palm ended up wrapping around the phone and resting on the screen somewhat. This would result in the screen not always unlocking right, sometimes selecting widgets and icons on my homescreen, restricting scrolling in the browser and random text entry.
Since I've altered my grip I don't get those problems any more.
My tattoo does this all the time....
Looks like exposing the phone to extreme conditions like heat or humidity makes this...
I used to keep my phone next to my Burning furnace i7 HP laptop and there is an LCD leak now on the screen :-(...since i noticed the leak, the phone started behaving more cranky....
update ...
Just to give an update, my phone is OK again now. By the time I got home a few hours later it had sorted itself out.
It's a HTC Desire HD, btw.
Damian
I had the same problem when I used a non-HTC charger.
Same problem here happens when charging with the original charger, when tyring another HTC charger with the same model number the problem is gone.
My guess is the charger that came with the phone is defective.
A workaround: I'm using a case for my DHD, when this problem happens I can get the screen to act normal by keeping the phones body (metal part) in direct contact with my hand.
The top part of my phone does not respond to touch anymore... it is impossible to bring down the notification bar... and once in a while the whole screen goes unresponsive.. tried factory reset but still the same problem..
am having the same problem since 2 days back
after reading some of the posts i found that the Digitizer For HTC G6 Legend A6363 should be replaced with new one i ordered mine from ebay
ebay.com/sch/i.html?_from=R40&_trksid=p5039.m570.l1313&_nkw=Digitizer+For+HTC+G6+Legend+A6363&_sacat=See-All-Categories
waiting for the item to be delivered
I've also got a touchscreen issue: the area of the notification power widgets is unresponsive... the rest of the screen works fine, but I don't know for how long :/

Do you have widgetlocker, by any chance ?
Or a lockscreen replacement which disable the notification bar during the "slide to unlock" state ?
I didn't know there was such thing as widgetlocker. I use CM7 latest nightly, never seen that thing.
I also facing this problem from last 2 weeks and i also think this is digitizer problem. If anyone else found the solution else changing the digitizer, then please post.
This is beautiful phone but htc added a poor quality things in it, due to which many users facing such problems.
Nah.. I dont think its because of widget locker.. its the digitizer..
well that's a shame, gotta buy a new digitizer on ebay after just over 1 year of use...
I know.. this sucks... Im planning to upgrade though.. Any of u guys have any suggestion?
Depends on your carrier if you want suggestions for an upgrade.
...but that would drive the post off-topic.
Sent from my HTC Legend using XDA App
I have the same problem. my screen doesnt work anymore because some water got in from the grill above the screen :S
should I try to take apart and dry off or shall I buy a new digitizer directly?
I think it may be a good idea to try disconnecting your digitizer and reconnect it as it just might be helping. I did it on my girlfriends legend and it has been working perfectly ever since. Maybe a good idea to at least try that before buying a new one. So i guess it could be in the connector to? At least this worked for me.
My touch screen dosent work at times. but after rebooting the phone the problem becomes solved. But the problem comes again after a week or so. Any suggestions guys??

I also have this problem, but if I wait a couple of minutes the touchscreen
becomes responsive again. Half of the screen works when it's unresponsive (right half of the notification bar and down). It's quite annoying but I cannot afford a new phone at the moment.
I'm also wondering if this might be temperature related, this problem reoccurred very often during the summer but stopped during the winter. But now (spring) it's back again.
My problem got worse and the phone became totally unresponsive, changed it, got a new phone.

exact same problem here, mine works when it feels like working, totally random, I simply can't understand why, I doubt it's the temperature... I think its in the device theres something wrong, I smack it numerous time and it works right after a big smack on the screen, or rub your whole hands on the screen, also, the angle you are holding the phone affects this problem, if none of these work, a phone restart always makes it work at the beginning. Oh boy did my phone took and taking much beating... oh well, I wish I could permanatly fixed the problem here, as I was thinking of handing the phone to my brother when I upgrade, I'm using CM 6.1.
I still recommend the same thing that i posted earlier here, her screen still works perfect.
I had the same problem few months ago. The problem is with the touch digitizer. I bought a digitizer on ebay and replaced it myself. After that my phone has been working fine. Its not that hard to replace it if you have a small knowledge about hardware.
I use to get that unresponsive screen issue only in the summertime, plus it gets worse if I add humidity (read: sweat). I just need to give it some time then to dry off/ cool down outside my pocket, and it's all fine again.
So I have an issue with a 2012 N7, warranty is long gone. I've tried all suggestions from billykxda's thread, but no luck thus far. I've also tried Google's official page on the topic as well.
I've left the device charging for many consecutive hours, both via AC power and USB, and I suspect my issue resides with the LCD screen. Also tried a hard battery pull. It's also important to note that I haven't undertaken any mods on the device at all, i.e. the bootloader is still locked and USB debugging is not enabled yet.
When I plug the device into my PC the Win7 driver notification bubble pops up, usually reporting either an Unknown Device or an "APX drivers not installed" message. I'm unable to get it to boot into Fastboot, Recovery, or Android OS. Plugging/unplugging the device via USB yields these driver messages over and over again, along with the Win7 sound notification, so the device isn't totally dead, but no amount of button combinations or 30-60+ second button holds are getting any response.
Has anyone else experienced these issues before? Do you think my device is totally dead?

Yes; I am also experiencing similar issues. Unfortunately, I have not reached a solution. I just replaced a broken screen for a friend. Once I got the screen in, I tried turning it on but didn't see anything happen. I began to research and thought I had the dead battery issue that most people get when leaving it unplugged for an extended period of time. I plugged it in using the wall adapter for a few hours, used the power+volume buttons and still didn't get any response. Finally, I decided to charge it with my PC. The PC recognized something was plugged in, installed drivers, and now I have a Nexus 7 in my connected devices list. While connected to my PC, I hold power+volume down and hear the USB disconnect, reconnect, and have an unrecognizable device attached. This leads me to believe that the Nexus 7 is working properly and the screen is not working. I have taken the entire device apart to re-seat all connections 3 different times and still cannot get it to work. I hope someone can shed some light on our issues!
Edit: I forgot to mention, I also tested the battery with a digital multimeter. It reads approximately 3.79 volts DC. I thought it may be important to state this in case the issue is battery related. I'm not certain what the correct value should be for it to work properly.
I am currently trying to diagnose this problem. Yesterday, I hopped on Craigslist and bought a working Nexus 7 for 50$. I am currently taking it apart to rob parts from it and figure out where the problem is. So far I have tested the battery. The battery reads approximately 3.78 volts DC so I can probably rule this out as my problem.
Also, I noticed something strange yesterday. I took the broken Nexus with me when I went to meet up with the man selling the used/working Nexus. While I was outside in very bright sunlight, I pushed the power button on the broken Nexus. I noticed that I could actually see the screen doing something. It was all fuzzy and had lines running every where, but you could in fact see it doing something. I think the replacement screen I received is bad, but I won't know until I start swapping parts.
AvidPhisherman, for now maybe try taking your Nexus out in very bright sunlight and see if you can see the screen do anything when you press the power button. Also, I'm not trying to hijack the thread. It seems that we have very similar issues. I hope to find something that fixes both of our problems.
Success.... kinda. I tried combining the broken Nexus 7 motherboard with the working Nexus 7 screen but it wouldn't fit since one is the 3G model, and the other is the Wifi only model. Next, I put everything back together on the broken N7, but this time I used the LCD ribbon cable from the good N7. Success!!! It powered up, and I can see the screen. My problem now, is that the screen is mostly unresponsive and acts like you are touching it in random spots, when you're not touching it at all. I'm taking it apart to re-seat the connections... again.

Hey redfox thanks for taking in interest in this! You're not hijacking the thread, your posts are very helpful. Good to know I'm not the only one experiencing these issues.
I'm just a hobbyist with an interest in fixing things, although I don't have much experience with DIY fixing. I didn't have a chance to try turning the screen on under direct sunlight, but yesterday I took both my non-working Nexus 7s (the first one I mentioned in my OP, the second one just has a bad/hollowed out USB port) in to a repair shop for a free diagnosis. I'm actually a business user, my company owns the tablets but I'm responsible for maintenance/tech troubleshooting.
Please keep me posted with updates as to how your progress is going. I'll post again once I get a report from the repair shop re: my issues.
Hi,
I have been having the same problem,
I bought my wife a used Nexus 7 and it worked just fine for almost a year then all of the sudden the screen would not function
there would be lines going through it but it remain dark.
thank you for researching the matter i will try to buy the part online and see if i can get it to work now!
if i understand it correctly there is no need for a new mother board but just a new LCD ribbon cable?

I cannot guarantee that it will fix your screen, but it is possible. When I had this one out in the sun, it did the same thing. The screen was super dark, and I could see crazy lines. Hopefully a new ribbon/cable will fix your problem. They are only a few dollars on Amazon.com

Hello fellow users! Quick update, I finally heard back from the repair shop.
Bad news - they tried swapping out the screen, then the battery, USB charging port, display cables, etc. etc. and nothing worked. Their diagnosis is that the tablet has a fried motherboard, and they're unable to repair and/or replace it
Good news - it cost me nothing to receive this diagnosis
Hopefully the outlook is not so grim for your respective N7s. Just wanted to post an update as to what I learned from this whole experience.
Hi guys, Reporting in.
Toke a while but i got the part AND found the stupid device!
After ALOT of fiddling, taking apart and putting back again i found out that the problem was the battery!
it looks like it was on its last leg and that caused all the strange screen stuff.
I dont have another battery to replace it so instead i hooked it up straight to a USB cable and into the socket and it works just fine
thanks for the tips and hopefully this helps someone else!
