Free screen test and repair guides for dead pixels
About Screen Issues
Screen Issues is a free website for people whose phone, laptop, or monitor shows spots, lines, or flickering. It is aimed at everyday owners who want to figure out what is wrong with their display before deciding on a repair or replacement.
The core tool is a browser-based screen test that auto-cycles through solid colors and patterns to reveal dead pixels, bright spots, backlight bleed, and color uniformity problems. No app install is needed, and it works on laptops, monitors, tablets, and phones.
The site also publishes step-by-step guides covering more than a dozen common issues such as white spots, black lines, blue spots, screen flickering, and burn-in. Content is available in English, German, and Spanish, so users can diagnose problems in their own language.
