Hello everyone. my steam deck OLED is out of warranty, and I live in southeast Asia; it is impossible to send my deck to valve because the repair cost and delivery cost will be more expensive than getting a new one.

So, my steam deck OLED has problem with the screen. when it is on the home menu and I press the backplate of my deck, it shows some stripes and flicker. and when I play some demanding games, sometimes it can stand for an hour, and sometimes it can't even stand for 5 mins. And after the screen goes black, I still can hear the sound of my game e.g. the steps when I walk around / the sound of pause menu and I still can shut down my deck using my feeling while the screen goes black.

When I connect my steam deck to the dock, I have 0 problem. tried to benchmark my deck for hours with hitman WOA benchmark and play some games after that, it works with 0 problem.

But I notice something, when the screen goes black, and I docked my deck, it shows no signal. I had to restart my deck while it is docked so my monitor can get the signal.

What I already do:

Teardown my deck, change the thermal paste, clean the ribbon cable of the screen, clean the connector of the screen on the motherboard.

So, what do you think is wrong with my deck? I asked around, some people said it is the display and some people said it is the CPU/GPU. I had no problem with replacing the screen by myself. but the OLED screen is not cheap, so I just worried if it is not the screen that has a problem.
