[Q] Screen colors messed up (Ribbon?) - G2 and Desire Z Q&A, Help & Troubleshooting

Hello Desire Z community.
I have met following issues with a Desire Z, and with a little bit of searching it appears that the ribbon might be broken inside the phone (The pictures are enormous):

}
However, after opening the phone and taking a look at the ribbon, it *seems* to be fine. There is no clear tearing in the ribbon, and it seems like it is OK overall. Can someone of you confirm whether this issue is caused by the ribbon, or by some other variable (screen, bad connectors maybe)?
The screen is distorted, and opening the keyboard "changes" the distortion. Also touching the ribbon while keeping the keyboard half-opened modifies the distortion.
This is my dad's phone, and he rather uses the phone in this condition than his Galaxy S4 :highfive:

now the left part of the screen is unable to be touched anymore. as could be seen in the screenshot below. the green areas are the ones that are broken

as this is a surely hardware problem, are there any other solutions than:
a. buy a new LCD screen (hard to find)
b. buy a new phone
thanks for the help guys
bump..........
Sorry
Since it is a hardware problem, I can't think of any other solution besides purchasing another LCD/phone. I'm sorry.
That said, I have put my defy underwater many times. The touch screen stop working when wet, but I had no issues with it once it dried. Maybe the problem was from the impact?

screen flickering and week wifi sensor

So I had my lg g3 started flickering suddenly, I didn't know what to do. this issue: https://www.youtube.com/watch?v=I9SqLlDOU1E
After a little research I found this solution: https://www.youtube.com/watch?v=Y12XCmAYTbw
I tried it and it worked fine for now(a week passed).
but since i have done the paper thing, my wifi signal is very low, even when my router I very close to me.
Any knows how to fix it? maybe change the placment of the paper?
Thanks.
Put a piece of folded paper between processor and body. Make sure paper push the processor and the size of folded paper nearly same as processor, so pressure on full processor not only at one point and put a small piece of folded paper on camera connector. May be it will solve your problem. Good Luck [emoji106]

Walkie-talkie background sound. Problem with the sound card?

I have an error that is most likely a hardware issue.
Everytime when sound is involved you can hear some constant background noise with some clicking and clacking sound at the end. (It sounds a lot like when you use a walkie-talkie: for example "blablabla, over and out." *chhhhrrrrr click* )
I tried...
rooting & installing custom roms
changing speaker
My sister's P600 works fine with either headphone, so I guess the problem is my specific device. It dropped a tool on the mainboard once when changing the charging port, could that caused some damage?
My primary question is: Where is the position of the sound card? (so that I can search the area for physical damage)
My secondary question would be: Any other ideas what it could be?

Earpiece

Hello,
I don't know if it was always like that or if I already got dirt into my earpiece.
To me it looks like the right two thirds of the grid of the earpiece are blocked (filled with something, maybe dirt). I will try to upload am image tomorrow.
Is it the same for you? I tried to get out or with a vacuum cleaner but it didn't change.
You can see what I mean on this picture

lol, never paid Attention to it. But you are right, I have EXACTLY the same right two thirds of the grid "blocked" .. Seems to be standard? Haven't found any issues with it so far..
That's as intended, the right two thirds are just cosmetic to make it look symmetrical, the speaker hole is only in the left third.
Hi there, I have too "dirt into my earpiece". Is it so on purpose or not?
Me too
I contacted my seller and he say me "it's normal". It´s no dirt but some like protective foil against dirt / dust.

Broken display or other problem?

I bought another broken SM-T805 and when i start it (cold start) takes about 15 seconds before the screen starts to malfunktion.
It starts to show small multi colored LCD defects on the left side and it ends up showing like you can see on the picture. The screen works to use and all other functions works.
What I can see and feel is that the temperature is sometimes a bit high on the processor and the screen. I have tried to change motherboard (SM-T800) and another battery, but the problem is still there. I haven´t been able to use another LCD-cable.
What do you think? Is the display broken beyond repair or could it be another problem?

Check the ribbon cable is seated properly in the FFC connector on the motherboard
Be careful with the locking tab. Panel I guess could be faulty
For heat issues see the mod thread about using thermal pads
