odd backlight issue - G1 General

I have a odd backlight issue going on with my G1 i took some pic and now the backlight won't come on no matter what setting I choose, if i slide open the screen and tap the backlight setting it comes on but it won't with the screen closed any thoughts? oh and when i open the screen I have to change the backlight setting in order for it come on

Question and hopefully someone has an idea could this be hardware and here is why I ask if I turn off the phone the backlight doesn't comeon at boot if i open the screen and boot the phone it does.
I am stuck and hate to set and dismantle the phone for no reason

did you drop it? a lot? lol not sure why that would happen unless the rom has a bug in it... what rom are you flashing? or is it stock tmobile firmware?

to be honest I don't remeber which rom I flashed it about a yr ago it has been working fine since I decided to dismantle the phone to check the ribbon cables as I noticed if i open the screen just a bit the screen works. however they were fine does anyone know how the screen switch on the G1 works i was thinking maybe it may be the problem as while i had it open I put power to it and played with the ribbon cable and it had no effect but moving the screen did.
Thanks,
yonu
P.S. sorry for long post

hmm. maybe a wire or sensor got unplugged or moved when you dismantled it... with out seeing it i cant really think of what could be the issue... i kno you tube has 100's of videos on taking apart the g1 lol maybe see if you skipped a step...?

Nope didn't skip a step I simply was hoping tat someone knew how the screen switch worked so I could try bypassing it as I think it is my problem

Crazy Tytn screen and button problem, please help

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?

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.

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

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.

Screen Turns White When Opening To KeyBoard

I have a MDA and i got it from a friend and used it find for about 2 months
and then outta no where the touch screen stop working but the screen would still display i tried reflashing it and i got nothing still non working touch screen then today i went to open it to type a text message and my screen goes completely white while in keyboard mode
anyone gotta idea whats wrong?
This is quite likely a loose hardware connection. There's a thread here somewhere with a link to the hardware manual. You need to take the unit apart and check all the connectors going to the screen.
The caveat to this is, if you've recently loaded any software, that should be the first suspect. Barring that, though, I'd fall back to the hardware fault.
alright yeah thats what one of my friends was saying
he has a mda also and he was like sounds like wires are coming lose
any ideas on where that thread is?

Resurecting a hermes.

My girl gave me a cingular 8525 today, it had come into her work and I am trying to fix it. I am a hardcore wizard user so i am very familiar with HTC, cooking and whatnot, but my 1st problem is I cant turn this thing on. The battery may be very dead, or the phone may be broken. All I have is my mini USB plug which doesnt seem to be compatible with the new phone. The hermes is squared off a little. I can get a little red light if I move the USB plug around a little. 1st thing, I have to turn this on, I have had my wizards battery be completely out of juice and I had to jumpstart sort of speak, so I was about to get on that with the hermes battery, but Im still unsure if my existing mini USB stuff will plug in with the hermes' slightly different sized plug. Anyone know? or if its just as simple as buying a new plug.
How many thread are you going to start on this issue? geez slow down a bit and you will get some help, but first start reading .
btw have you even thought about doing a battery swap huh? or maybe using the right plug since you know its not the right one...i
bam. update, hermes is on, jumpstart solved the issue... no backlight though. checked backlight settings and they were up all the way... ideas?
After unlocking and flashing to farias rom and still no backlight, I think its safe to assume that the problem is in the hardware. anyone know how to replace the LCD screen or where I can get one?
whoa crazy another update: I left the phone alone to charge, battery is at 60% and screen just came on everything looks peachy! I am noticing it dimming and getting brighter occasionally though.
The phone is acting very strange, still unsure if its the hardware thats acting up. it went back to not working, the screen was lit up just once for maybe 20 seconds, noticed that the keyboard backlighting does not work either, but for that 20 seconds when the screen backlight was on, that was as well. Starting to think that there may be a loose connection somewhere inside the phone, or the light sensor is somehow not working and screwing it up. If the screen lit up once, then to me that means the backlight is not burned out. If anyone has any ideas, please please let me know. I know its a weird and uncommon problem but someone may have gone through it. Thanks again.
It is probable that the internal connectors are loose and or battery connections.
Really, all the information you need is already posted several times over. So use the search. But as a starter for dismantling and the service manual see the website in my signature.
You will need some skill in dismantling and a fair bit of care and patience or you will end up with something in worse condition than now!
Mike
interesting update for those who dont care, it appears that I have a very sensitive light sensor, after downloading the official wm6 from at&t my keyboard now lights up in the dark, before nothing lit up, just the dial and end buttons... I wonder if it could be the software or something in the registry thats not clearing being the reason why I still have no backlight... but last night it came on for about 10 minutes afer me not touching it at all... strange little device. oh well, if theres any ideas id love to be able to replace my wizard with this...

The chargers are the same plug. The 8525 plug is squared off for the headset. They dont want you to plug your hermes headset into your wizard

Help with diagnosing LCD problem

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.

Black Screen But Phone Is Still Working??

Hey guys
Just bought my moto x play. And on the same day it screwed on me. So after i got the phone i updated to Marshmallow, And left it in my room to charge. On my way back I realized my phone was not turning on. I turned it off and turned it back on but nothing happened. I only felt the vibration of the phone and seeing the screen light up black pixels (no idea what the proper term is)?
I can still use the camera with the twist gesture and i can still hear the phone taking photos when i click the volume rocker. But the screen is black and i cannot ue touchscreen to take phtos. I also noticed that the LCD lights up black again if i lift my phone up. Just like moto display would do with notifications. I also hear notifications on my phone but nothing else. I have serached for a fix but nothing anyone else have this porblem?

Most likely it's a hardware issue.Are you able boot into bootloader mode with screen working?
boot into recovery and factory wipe it.

I faced similar issue with my previous droid maxx, phone was on but only the screen's backlight came up. It happened all of the sudden when I was watching youtube. I thought the LCD ribbon connection was loose so I disassembled the whole phone and put it back on but no success. I ended up leaving it on the desk and one day the screen woke up on its own. The battery was at 1%, not sure if that triggered anything that fixed the problem. Maybe you could leave the phone until it drains out the battery and see if it could work for you.
Another way is to get into fastboot or recovery and do a factory reset
Maybe the flex cable is loose or disconnected
Assuming you haven't unlocked the bootloader,ask for replacement.

Hi Danny_Cai. I'm currently experiencing the same issue with my Moto Z play smartphone. So I wanted to ask, did you just replaced the phone in the store? And what was an actual cause of this problem?

Hi Danny,
I had a similar problem with my phone. Not under warranty so took the back cover off using a T3 star bit.
Radio Shack probably has it also.

At the bottom of my phone, there are two spring contacts. One was sitting loose and must have been causing some kind of problem. It fell out, and I did not reattach it. Haven't had a problem since.

It may be something as small as that. Not sure what it was for but haven't noticed any difference in the phone.
Hope you find your solution.

Guys i also have this issue, did u figured it out what exactly it is?
