Have 5 sr353's i bought off Craigslist as is/parts or fix all with the same symptoms. No power up/standby light. Managed to fix 1, bad relay on power board, but the others obviously have issues that far exceeds my tiny bit of knowledge of circuits. Just started DIY electronics as a new hobby and managed to repair a couple Xbox ones and car audio amplifiers, but this little ventures turning out to be way above my paygrade!! Now i know about the HDMI board snafu with this particular series, but wouldn't think that would keep the units from powering on. No relay clicks, no nothing. Help!!
