I have Lumia 950 XL Screen blinking and in stand by mode goes to the green color

[19870213]

Phone Works Fine, Screen doesn't damaged, touchscreen works fine.
But I have an issue with my phone, my phone screen blinking to the blank every couple seconds.
When I don't use my phone and it goes to standby mode, the screen goes to the green color, but when I wake up phone screen come backs to normal colors, but screen still blinking every 2 seconds to blank.
But when I do updates or restore the phone, screen doesnt blink at all and all colors looks fine.
I tried connect my phone to tv, everything works fine.
So I guess is not hardware issue, but also I dont think it is software issue also, because I tried install different versions of software and it doesnt fixed my issue.
Anybody have an idea what could make this issue?
Anybody have same issue?
Any suggestions How can I fix it?

I think it's hardware...

I've replaced my screen a lot. I've had glance completely not working, glance quarter working (flash for a moment), whole screen goes green until I smack it, darkest bright settings turns out to be pretty much black.

But everything works fine whent its doing hard reset or updating firmware.It takes about 3-5 minutes and screen doesnt flashing.It starts flashing when it starts load windows, when windows icon appears on the screen and it flash all the time.

Could be the IC for the graphics on the board is going out. So when it loads the OS and loads the proprietary panel driver you see the problem. While booting to the reset screen basic display drivers are loaded that rendor basic display properties. Could be over time the hw is degrading. It also looks similar to a ribbon cable issue. How old is it?

Yea, it's likely something wrong with the low power state (whether its the right term or not, but that's when the symptom happens), full power it's fine... For now. The problems i talked about on my phone were not while using it, more around the low power state like glance, or dimming on lock screen before going dark.

Display Flex Cable fault.

So you think if I replace this cable "Display Flex Cable fault, 00813X7" it can help solve my problem?

The Flex cable for the LCD is part of the LCD. I imagine there is a way to replace that cable by completely dissecting and disassembling the OLED, but you are better off replacing the whole panel if you think it is the panel/display flex cable as the problem. You need a heat gun and quite a lot of patience to separate the OLED layers from each other. They even make special equipment for that because of the difficulty.

Probably no. If I'm not mistaken, this cable I never changed. It always goes with me to my next me screen. So my green screen issue didn't appear with the...

I didn't think it was the cable inside the screen assembly because I thought there was a fold at the bottom connector, possible a brand need one doesn't fold?

I've solved this cable several times and it's a screen problem.
Otherwise, I'm sorry, I wrote the wrong order number. To replace the display cable, you need to unpack the display.

I think I have the exact same problem. Mine was water damaged a while ago. I tried leaving it in rice container for a while but did not help. Resetting did the same as described here but after restarting it was again the same.

So what did you do to fix it? The cable or screen digitizer?

Thanks,
