A month ago I bought used HTC Touch Diamond. The touch screen was cracked so I decided to replace it but it turns out that I had to replace the lcd too. Well I bought it- touch screen with lcd and then replaced it by myself.
That's where my problems started. The phone was so hot that I thought that it's going melt and the battery was drained for 2-3 hours completely. Last times when I was trying to launch the camera I was getting a error- device.exe can't start or something like that.
I've put on the processor under the cover termopaste for better cooling and detached the main camera- know my phone is never getting hot even with gps tracking and the battery life is good but I don't have a camera.
Also right below the battery in the middle there is a screw- I removed it because when I put it my external speaker doesn't work. I had a problem with the internal speaker too and it turns out that when I connect the pin on the internal speaker closest to the vga camera with the panel the speaker work. So I soldered the spot where right pin (the one closest to the vga camera) of the speaker makes the contact with the board with the closest part that makes contact with the panel and there is no more problem with the internal speaker.
Is it possible to keep this battery life and temperature and to have working camera ?

So, My diamond woke up me this morning, as usual. but problem...
my Diamond's screen didn't respond. and seems like under screen there is like vaccum. whole digitizer is pushed down, haven't had this kind of problem before. How can I get rid of that?
Last night things worked great.....
You can`t get rid of this problem. It`s a HTC known issue.
A friend who ownes a Touch Pro has the same problem. If he puts his headset to recharge during the night face down , it will cause the interior of the touchscreen to vacuum wich renders his phone operable , but without touchscreen capabilites ( for a short while ).
I replied thinking you left your phone face down during the night. If not , then my solutions is invalid.
well i left my phone charging whitout pouch onto glass table, so that screen was down.. yes the problem disappeared but about 2-3 weeks my phones screen was dead because here(in estonia) january s temperatures are as low as -30C and screen needed heat to come out of vaccum. it happens occasionally(never happened before). to conclude it I bought new screen and changed screen myself
Well, I fixed my old broken G1 with new screen, touchscreen panel, case and keyboard.
Now I have 2 issue:
1) Sometimes my touchscreen goes grazy!! If I use the touch test application I see that sometimes when I touch the screen in an area there is another virtual touch in another zone of the screen. I read that it can depend from the current source when I charge the phone.. but I'm going crazy!! I opened my phone 10 times (I thought there was a problem in the cable that link TouchPanel to LCDPanel, because when I lock the cable with the clip it tends anyway to go out from the connector, now I put some scotch tape to fix but the problem is here.. so I think is another problem).
2) My volume rocker doesn't work!!
I bought 2 new keyboard to fix this problem, but no one of that fixed the problem. I thought the first new keyboard had volume keys broken, so I bought another one, but the problem persists!!
Now the Touch problem rarely happens, but the volume rocker is completely unusable..
Someone have experience about G1 assembling/repairing ?
Thanks and sorry for bad english
if you have put in multiple keypads have the same issue i would assume that it is the connection going to the motherboard. just a guess there but its either that or you have had a bunch of faulty keyboards.
only other thing would be a software problem
does the keypad work in recovery (let you go up down throughout the list) ?
as for the touch screen, probably need a new digitizer or flex cable, both are cheap and it sounds like you have the knowhow to replace them.
Ok, but digitizer is new!! screen also is new, and I have bought a total of 4 flex cable because I see that they are fragile (I broke the first I bought).
I tried to change flex cable but the problem remain the same.
The only thing that can be damaged is the LCD cable that links to the flex cable: it has a small cut where the cable have a curve, but the cut don't reaches the contacts (the cable is transparent). I also use some glue and scotch tape to mantein lock the cable.
The digitizer cable is connected to the LCD cable, and then they go to the flex cable that connect them to the motherboard.
The strange thing is that seems a software issue, because if I turn off and than turn on the screen, the problem is fixed for some seconds, minutes and sometimes hours...
Another strange thing is the possibility to control the screen with some metal objects from the moment that the virtual touch problem appear (I can control the screen also without touch it, with hand and piece of metal)
video:
have you tried a factory reset if you think it may be a software issue? if that dosent work you can try install a whole new rom.
really it sounds like it isnt the hardware since you appear to know what youre doing. i have a had a few phones that had screen (digitizer) issues and a new rom flashed cured it just fine
since you dont mind putting a few dollars into it, and your familiar with the inside, you can always try to pick up a cheap motherboard or spare phone from ebay or what have you, then swap the motherboard and you could then hopefully find out if it is the hardware or software

Huh sounds like you got a cheap digitizer than. Most good digitizers use heat to touch. If it's literally touch, then sounds like its a fake/meh digitizer. i hate the digitizers that aren't heat, but press. I see them all the time in those first samsuck touchscreen phones. And they usually die in a bit. I had a Samsung behold with a screwed up digitizer

Yes I flashed 3 or 4 roms after a wipe (I tried also super-wipe.zip), but the problem is here..
The digitizer works well some times, but sometimes get crazy (you can see in the video).
I don't that my new digitizer is fake, but I really don't know!
BTW I'm trying to repair my phone for fun (now I have desire z) and because I am fascinated by my old G1.
PS:
I see another strange issue--
If I touch the screen when the phone is on a table the screen digitizer is not very sensitive and can't take input from fingertips.
If I touch the screen when the phone is in my other hand, the screen digitizer is a lot more sensitive and it take input from fingertips.
My impression is that there is an electric field or something similar that disturbs the digitizer, and when I take the phone in my hand I discharge that field to ground. Also when I turn off the screen, seems that the electric field discharge so when I turn on the screen is ok, but after some seconds the field returns to disturbs the screen.
I really don't know, but is the impression that I have.. something that is not shielded.
Now I'll try to use my phone in airplain mode.
Thanks guys, I'm happy to see that this forum is still very active
Alright so basically 5 weeks ago I had my phone in the pool with me, just a shallow backyard pool. And somehow water got into the flaps tripping the water indicators.
I felt it overheat and the camera button being held down, so i basically turned it off and drained its battery. For a few days it was fine, but couldnt hold a charge and everything was fine, but some water in the screen. And then it decided to invert and flip itself. From then on it hasn't been turned on.
I sent it off to Sony but they send it right back to me unfixed, which kinda confused me, because i got a message saying the Claim was approved and they'll be sending a new device out to me. And then when i recieved it, it was my phone, with the loudspeaker grille nowhere to be found.
So now ive decided to take things into my own hands. Where do you guys think the problem is?
Currently its like this
No Water In Screen
Phone Works Perfectly
Screen Mirrored and Flipped
Top of Digitizer not responding so cant pull down menu
Ill be opening it up pretty soon so Im just trying to get an idea of where i should focus my search.
The speaker is also where the screen/digitizer is connected at.. so if there is no loudspeaker there you may have a problem because of that!
Also opening the phone is very tedious and I advise against that.. they should fix it!
There has to be some kind of app that can flip the screen.....
Hello everyone, I havent been on XDA in a while, but now im reaching out to the community. I am having weird issues Like overheating, "false screen starts", very dim screen, unresponsiveness while charging, camera buzzing, and bad camera quality.
For starters, The overheating is due to the Snapdragon 808 chip. It was rushed in development by Quilcomm. I disassembled my LG G4 to find that LG had put an RF shield on top of the CPU. Between the CPU and the RF shield is a thin layer of what looked to be mylar tape. I had an idea, what if I removed the tape and put some thermal paste between the shield and the CPU? I might try that as it wont really effect anything. Ill give you guys an update.
2nd: Screen issues. I have noticed when I turn the phone on from standby, the screen is very dim. Another thing that happens is the screen will be on but not show anything or have "static" on the screen. Both of which are very dark and hard to see in normal lighting conditions. This is fixed by putting the phone to sleep and turning on again. Someone in my family got a LG Vista and had a dim screen issue, but it couldn't be fixed by reboots. Another thing that will happen is a flash on the right side of the screen of multi-colored static. The flash is about half a millisecond, however it doesn't happen alot.
3rd: You know what happens when you try to use your phone in the rain? And how it does random things or even doesn't respond to your touch? My G4 has that issue while its charging. It happens most on my Samsung Quick Charger and as well as some non-quick charge chargers. This is annoying when I want to use my phone on a near dead battery, and is doesn't help that the Snapdragon 808 overheats when plugged in.
4th. Camera Quality: I think its the lens, I dont know yet. I noticed that very rarely it starts to buzz and you can feel it moving. Why? I have no idea.
Does anyone else have these issues? Please let me know. This happens on various ROMs (stock included). On android versions 6.0 through 8.1
I've got a replacement screen that my friend had in his house. Mine was broken (both the display and the digitizer, the latter was acting very weird). I did the replacement myself, and when I was finally done, I noticed something. The Touch Screen wasn't working (I could see the image but no input was recognized). I tried opening it and checking every single cable to see if there was anything wrong, but there was nothing looking broken or out of place. When I was going to test it, I noticed another very weird thing. It actually works if I keep the back of the phone off (not the back interchangable cover, I mean the back of the phone that is screwed in place). The problem is that this phone has a very annoying design that makes it so the Wi-Fi, Speakers, Camera and some other stuff don't function well with the back plate off, speacially the Wi-Fi.
I trully have no idea what is happening or what is causing the problem with the touch screen, and have no idea why the back plate makes the screen act funny. Can someone please help me figure this out?
Perhaps something in the digitizer's flex cable is shorting with the back panel. Try putting a layer of electrical tape between the flex cable and the back panel.
