Hi all
The OP here. Sorry for being late for the party. Was caught up with tons of other stuff. So here's the latest update from my side:
I shipped the receiver to the authorized service center in France. The guy could not replicate the issue! Apparently, he left the receiver on overnight multiple times, sometimes with speakers connected, sometimes without but it would always stay on. I told him that was weird and since I'm having the problem all the time, could he just take my word for it and replace whatever part he thought might have been faulty. He told me they were not allowed to do so. I had no option but to get it shipped back to me.
Back home with me, the receiver started its antics again. Initially it would shut itself off randomly as before. But then after a few days, it refused to turn on altogether. Even after disconnecting it from the mains, and removing all the speakers and the other connections and discharging the capacitor by long-pressing the power button, it would not turn back on. Sometimes, very rarely, it turns on but then goes off immediately. disconnecting from the mains and long-pressing the power button makes 2 or 3 clicking noises and then nothing. I have made a short video showing the issue:

I have re-contacted the service guy and he tells me that now since the receiver is not even turning on, he can perhaps do something. Now I am debating whether to send it back for repairs and lose more money or to just call it a day. Have used many receivers in the past but none gave me so much trouble.
Cheers
