Old AVR Repair
Sorry guys. No real troubleshooting here. This one was pretty obvious. I thought I'd post it in case it helps someone else with a similar problem.
My old Sony STR-D550Z AV Receiver started taking much longer for the output relays to click on and a couple of days later, I got no output from one of the channels.
Sure, a relay driver transistor could have been the problem, but I was reasonably certain that the mechanical relay had failed.

Here is the relay board for the front L/R channels.

Removed two screws.

Out with the old.

The only markings on the relays.

I entered DH2TU in Google and found a place at Ebay that sold replacements. They arrived the very next day after I ordered them and these are them.

In with the new. I cleaned the board with DeNatured Alcohol.

Ready to put it all back together.

Now I can't get it to fail. It works like new. I hope this helps somebody with a similar problem.
