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.

Thanks Mike.
I will give that a shot.
I haven't installed any new applications recently, so I don't think it is a software issue.
Thanks again.

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.
A friend of mine brought me his Wing to look at for him. If I turn on the phone on it boots up and the screen looks just fine. When I slide the screen opened to use the keyboard the screen freezes and when I close it again it gets all jumbled up. There are lines going through it and I can not make out anything. The phone isn't locking up at this point because I can press menu buttons and other hard buttons and see the screen react, I just can't tell what is happening.
I assume that this is a hardware problem. I was thinking that the cable that connects the screen may have been jarred loose or damaged in some way. If that is the case do you think that it would be as easy as opening it up and repositioning the cable? I don't have any experience with this phone specifically so I don't know if this is a common issue.
I was also wondering if it is possible that this is just a software issue. Maybe the function that rotates the screen for use with the keyboard is messing up and jumbling the horizontal and veritcal lines when going back and forth. I was thinking about doing a hard reset and seeing if this clears up anything. Any thoughts?
I appreciate any help. This forum has always been there when I needed help in the past. I'm sure somebody out there has much more experience and knowledge that I have and can lead me in the right direction.
Thanks for any and all help!!
Update...
So I went ahead and tried the hard reset first hoping that it might be a software issue. I am now at the screen that says "Tap screen to setup your Windows Mobile based device." No screen touches are being recognized. This seems to support my thoughts that there is a loose cable or bad connection. Agree?
I just slid the screen opened to see what would happen and it faded to white.
Yep, if my experience with the Wizard tells me anything, the flex cable from the main body of the phone to the screen is either loose or damaged somehow. Even a small nick or cut into the flex cable will cause it to stop working correctly. I would hunt up the Herald service manual and take your device apart and see what you can find.
Thanks ... I downloaded the service manual and plan on taking it apart. I have to make a run to the store though and buy a small enough Tork screw driver. T5 or T6 I believe.
Thanks again, I will post with my findings when I get going on it.
now what?
So ... I have the phone completely torn apart. I do not see any loose or damaged cables. It was dirty inside the phone but other than that everything looks just fine.
Does anybody have any advice as for things to look for, that might be causing this problem, while I have this thing torn apart?
Hi all,
My trusty blackstone has begin letting me down and I don't know if flashing a new rom will help, or if it is something physical that is breaking / broken. I'm using the Stonehenge ROM with CHT and everything has been fine for months.
Recently the touch screen allignment just seems to 'wander' sometimes just a little, other times quite a lot (so much that using the fake hardware buttons at the bottom of the phone, brings up the start menu). This means that intermittently I cannot answer calls, and typing a message on the SIP is an absolute nightmare!
The start menu icons do not seem to be as affected as the home screen and CHT, and I can quite easily get to the phone settings and recalibrate the screen - this will help for a short while but the alignment drifts again.
Restarting the phone has a temporary positive effect but it doesn't last.
Anyone else experienced this?
I have exactly the same problem.
Dissembled the whole device, blown some hot air but didn't help. Seems it's a HW fault. But I have a doubt whether the problem is in digitizer or in control board.
It's definitely one of the more frustrating problems that I've ever had with the phone.
I might try flash a new ROM then give up if that doesn't work. At least I won't be tempted to disassemble as it has already been tried, tbh I'd have just tried the tin of compressed air too, I don't trust my soldering skills for tiny electronics.
It is getting progressively worse, the touch area of the screen has slipped so low now that I can't use half the screen.

Have a look on this one, maybe this will help you...http://forum.xda-developers.com/showthread.php?t=538113
I'm having several problems with the touch screen on my LG V20 H918:
1.) It does not recognize any of my taps
2.) It seems to think I'm tapping it over and over near the bottom of the screen
3.) I can see a faint image of the previous screen (i.e. the image from the lock screen or the splash screen ghosted in the background)
What I have tried so far:
1.) Took it apart and searched for any possible shortages or debris causing issues
2.) Gave it a thorough cleaning with 99% alcohol to remove any possible unseen debris
3.) Completely recharged battery and attempted to boot again
4.) Factory reset
5.) Purchased and installed a new screen with the digitizer and the works (yet the problems still persist)
Since I've completely replaced the front half of my phone, I know it isn't an issue with the screen itself; there must be an issue with some finer part of the phone that I'm unaware of.
I'm planning on taking this to get repaired, but before I do, I want to see if I can pinpoint the problem myself. If it is something relatively simple, I'd prefer to fix it myself and save some money (I'm already $600 in the hole with this). So I'm looking for any other suggestions or possible insight into this problem. Thank you in advance.

Ive experienced this in very specific scenarios. Only on specific apps and mainly with on web browsers on certain web sites.
Never had any of the other problems though.
Yours would have to be a hardware issue I'd imagine if factory reset didnt help
