Great news, found some MP9148 (the original IC401) lying around and tried to replace it: MONITOR WORKING!
I take some measurement for the IC401, 402 and 400 if someone need them, from pin1 to pin8:

400: 300mV 19V 3,3V 0V 8V 2,4V 5V 790mV

401: 609mV 3,3V 1,1V 3,3V 0V 1,8V 5V 609mV

402: 286mV 19V 12,8V 0V 15V 3,3V 4,8V 800mV...

Removed IC401, all shorts on caps disappeared!

Ordered new components for IC401 and 402 (not shure if is working or not).

For the C508 shorted near the audio jack: if you plug a jack, the short will go away. i think is intended to work this way.

Hi all!
Im here for the same problem, 27gl650 dead...
I think my problem is IC401, it gets extremely hot in less than a second.
Reading here, the MP2122GJ can be better than the original and perfect for a replacement.
However, I would also like to order some spare ICs for IC402 and IC400 but i can't find what they are.
I have IAGCN for the 402 and IAQTP for the 400.
Can someone help me identifying those?

Thanks!


PS. I have a lot of cap shorted to gnd around the 401, like C438 C439 C444 C403 C401... i will desolder the ic and...
