For some reason the screen goes white now and then. I'm using a attiny85 as a battery low warning could it case the screen go white.

Sorry took so long, vacation. I Tried taking the attiny off. Still the screen went white after some time. The other problem could be that I added four bush button to the board. I added gpio configure to config.txt for the buttons.

Update.
Screen goes white even when attiny85 and buttons disconnected.


Started from scratch. Installed buster and the software still the screen goes white.

What screen are you using and how is it connected? Have you tried it on another device, or tried the RPi on another screen to see if it's exclusive to the screen or the RPi?

Tried using raspberry pi 2 seems to work but when using raspberry pi 3 screen goes white. Using kedei 3.5" screen. Rasperry pi 2 gives a under voltage warning but raspberry pi3 doesnt. Could the problem be under voltage the screen doesnt have enough power?

EDIT
The raspberry pi 3 on boot the screen goes white all the time now so most likely I some how damaged the board.
