We had some thunderstorms last night and when my wife and I got home we noticed our Yamaha HTR-5490 was not on. Everything else A/V wise was on and appeared to be OK. So first of all not sure if the thunderstorms even had anything to do with it. But when I push the power button the display turns on for 3-5 seconds then shuts down. I found a link to Yamaha for factory resetting the 5490 and went through those steps. Everything seemed to work correctly while doing the reset, the digital display stayed on until I got the PRESET RSRV display, then I shut the 5490 off. It then says to wait 5 seconds and turn on the 5490. Well it does the same thing as before 3-5 seconds of display then shuts off! Is there anything else I can try before throwing my hands up??
