I have an optimus stav 3670 stereo reciever that wont turn on. I have located 3 fuses, all test good. No lights, click, or any sound or reaction when power button pushed. I'm hoping there is a 4th fuse...

Mike, sounds as if it's not getting voltage to the remote control receiver circuit? Meaning that there is a low voltage (5volts) that sits there and waits for the signal from your remote to turn the unit on. This is also through the front power switch which is also tied to your on-off power relay. I would check for 5 volts around that. More that likely you a 5 volt regulator shot. Hope this may help?

Remote sensor is not working I assume, i have been unable to get any universal remote to work so I am thinking it is the actural sensor in the reciever. My receiver is not on the list. I inherited an...

I doubt that its the sensor. you can check at radio shack for a replacement remote. I have yet to see a universal remote that controls receivers. they would have to order it if available. use the catalog # on the back of the receiver (31-XXXX) or let me know the # and I can check into it for you. is it an stav3560 or 3250?

I have found that on some units you unfortunately need the remote for more advanced settings. Sorry man.
