Screen & Dead Pixel Test
Fill the screen with solid colours to spot dead pixels, stuck pixels and patches.
9 FULL-SCREEN COLOURS
The screen fills with each colour in turn. Tap to advance and scan every field for a dot or patch that doesn’t match — that’s a dead or stuck pixel.

How did it look?
Look for any dot or patch that stays a different colour on every screen. A spot that never changes is a dead or stuck pixel.
This is a quick self-check, not a full diagnosis. Physical and board-level faults need a proper bench test — which we do free before any repair.
