Repair RX-V667 or buy something new?
I have a quick 'what would you do in this situation' type of question for you guys. I have a RX-V667 that I've had for a few years now. It's been great, no issues at all until recently, and it has all of the features that I really need for right now. I'm not planning on making the jump to 4k until it becomes more mainstream, I currently have a 5.1 system that works well and that I won't be expanding until I make the 4k leap, and all of my devices are hardwired by Ethernet.
So my RX-V667 recently died. I tried to turn it on one morning and it flicked right back off by itself. Tried a couple more times and it stopped coming on at all. I did some Googling and started to troubleshoot. I disconnected everything from the receiver and plugged it into the wall by itself to make sure none of the wires were causing a short. Still wouldn't turn on. So I held down the Tone Control and Info buttons and then turned it on, and it came on and gave me the readout "PS PRT : L 2" on the screen. I can't change any of the settings or access any menus, and when I turn it off and back on it goes right back to turning itself off until it eventually stops turning on at all. So obviously this thing needs a trip to the repair shop.
My real question is this: is it even worth taking this to get repaired? Does anyone know approximately what this will cost to fix? Based on some online reading, it looks like others have paid $75 up front for just a diagnosis from a Yamaha certified repair shop. Does it make more sense to take this in for repairs, or to just buy a new RX-V577 or RX-V575 from accessories4less? Those will run me either $250 or $290 for a brand new unit with a limited warranty. What would you guys do in my situation?
Thanks so much for any help you can give me!
