Red light flashing on marantz Av receiver

[Akshit2111]

The problem many a time is the hdmi board. They are so delicate that a little bit more electricity or slight variance in any factor blows it. Reset everything according to the manual and run analogue cables and see if it works.

Hdmi board issue. Had to incur 25k.

You should check for S/C at +/-15V lines, then check fuse resistors R903 and R904 (0.47R/1W) for +/- 15V regulators.
