Yamaha RX-V371 No Power, HDMI Problem

[mosscomes]

I've got a suddenly dead Yamaha RX-V371. A few weeks ago, there was a considerable delay in switching between HDMI sources (black TV screen, sometimes a "no signal error." Then it just shut down.

Now, there's no power, hitting the on-off button does nothing. I get one click when I hold the on-off and reset buttons, but no power nor flicker from the LED's.

The Fuse is OK. Power out from the Operation PCB seems ok. I tested transformer and that seems to be ok (no Thermal Fuse issue).

The power problem with these models seems to be common, but I've not
found anything on the HDMI switching issue, which may be where it all started.

Any ideas?

HI Did you have any luck finding a solution to this . I have two of these units showing similar symptoms . I have narrowed it down to being a problem on the hdmi board , which is also the main control board and yes the hdmi issues seem to progress into no display (which most people think means no power ) I have spent a bit of time checking voltages on the board and everything seems ok . at this stage I can't justify spending any more time tracking the fault but it does seem very common from the brief searches I have done so maybe someone has spent the time .
