Viewsonic VS16217 strange problem - white flickering screen on power up

[domu]

As per subject, on power up display shows no image, but white
flickering screen. Strangely, it only happen after power was lost
when it was on. After power returns - white screen only, but if
disconnect power for 12-24 hrs, and connect then again monitor
works normally.

Any clues how to go about it would be greatly appreciated.

Take a hair dryer and heat the board up to 40-50C and then turn it on. See what happens…
