Just in case anybody else has this fault. All components in my thermal pic have around 45c with the CPU beeing the hottest spot.
But the fault is caused by the buck converter.

Working again! I replaced IC402 and IC700 and got a standby LED.

Thank you for your help. I had too much focus on the thermal cam. I found L407 (in by board L408) short. Removed the inductor and got 24 ohm back. So should be fine for a low voltage rail? Short on converter side stays....Last edited by dbuergi; 09-10-2025, 03:54 AM.Leave a comment:

Hi all,
my 27GN750 also died. The board shows 4 hotstops.
IC202 (CPU), IC701 (marked TUSB8041I) and both buck converters close to the two bigger chips. The one under the CPU in my pic is the biggest hotspot. Would you change the converters before changing the CPU? Around 40c on the CPU doesn't seem too hot since it also has a big cooling pad....Leave a comment:
