Screen does not power up, power led flickers when pressed.
Backside open showing power supply board left and mainboard right.
After searching zee internets found forum posts describing exactly same error, forum suggested replacing all mainboard electrolythic capacitors.
Bulged mainboard caps.
Replaced all zee caps on mainboard with 220uF.
Also replaced zee cap on power supply board, sticks out now. If zee screen fails again (not powering up, power led flickers) the rest of the power board caps should be replaced too.
Screen working again hurray!
