Title: A500 Rev5 corrupted boot screen
Post by: binarybrother on September 30, 2025, 09:38:47 PM

I have a A500 Rev5 which has intermittent boot problems. Sometimes it will get to the boot screen with image corruption and then won't boot anything. Other times it boots fine and works, other times it will boot and then later image corruption again. And it will also sometimes white screen on power up.

I’ve removed the custom chips, used a little contact cleaner and put them back in and this hasn’t helped. Any suggestions on where to look now?
