Toshiba C55 No 3.3/5v rails [Fail] - LFC

Описание к видео Toshiba C55 No 3.3/5v rails [Fail] - LFC

I thought I was onto a really good fix with this laptop, but after a long slog I hit a dead end in all directions. Posting this because I feel like there's a lot to pick up along the way.

The last clue I had was; 3.3/5 volt reg heats up. Low resistance to ground (2.3ohm) on the feedback pin. The 'short' can be isolated from feedback, but the regulator still won't turn on while isolated, presumably because another monitoring chip elsewhere isn't seeing the isolated feedback.
