Samsung S22 Ultra CPU failure - diagnostics and diagnostic warm-up
The phone won't turn on, is stuck on the logo, draws 200 mA, and shows no signs of life – sound familiar? These are classic symptoms of a failing CPU. But before you dig into the board, you need to make sure that the problem is actually the processor itself, and not a dead battery or a disconnected ribbon cable.
In this video, we'll cover the initial diagnostics of a processor failure on a Samsung S22 Ultra: how to read the symptoms, avoid false positives, and how to perform a diagnostic warm-up to confirm the problem before repairs.
🔧 What's shown in the video:
— Symptoms of a processor failure: rebooting, freezing on the logo, 200 mA on the tester
— Why a dead battery can disguise itself as a processor failure—and how to check it in 30 seconds
— Diagnostic warm-up of the processor: temperature, time, tools
— Why warm-up is only a diagnostic, not a repair
— When can you make a diagnosis and proceed to a re-roll?
