SR8825 No power. IC1 getting hot

Before VC died, it was restarting while cleaning. After i checked it, i found very high power consumption and hot IC1. VSS and VDD of IC1 in shortcut.

I think some of voltage regulators died.

Looking for solution or full schematic.

Hi @kotpomojnyj ,

Don't know the answer but have you tried searching online for the schematic, using the 'board number" of the pcb instead of the appliance model number?

Sometimes schematic diagrams show up this way and not when searching for the model number.

Just another option to try.

Have you tested the regulators to see if any are short circuit or open circuit? One may have simply just failed and this caused a cascade effect perhaps

@jayeff I did. dj41-00551a shows up only spare parts. typical shaped regulators\stabilizators i cant recognize, like Fairchild db30af.

It's a trap!

@kotpomojnyj post some GOOD pictures of the PCB with your QUESTION. that way we can see what you see and hopefully can help you out further Aggiungere immagini ad una domanda

@oldturkey03 done. IC1 right under the camera.
