Disconnect power then check all of your input and output connections on BOTH ends including the speakers to be sure they are firmly seated into their respective terminals. Fix any of those, reconnect the power cord and turn back on.

Do you have your receiver output connected to the input on your TV? For example, if the receiver is in connection number 1, is your TV set to connection 1?

Yes, although it (AVR) does not support HDMI only component video.
Connect the audio to the receiver and the video directly to the TV if you have inadequate video inputs, or want to take advantage of the HDMI.

There is an internal reset switch mounted on the transformer board. Open the unit, look at the boards attached to the transformer, the pushbutton is facing up. Measure the voltage on the 2 pins of the switch. If it is a logic low, the switch is partially shorted. Replace the switch or just cut the jumper wire just below thw switch. When this switch fails, it constantly resets the receiver and stops it from powering up. It does not fix a protection mode problem.

I'm having the same problem only difference is I baugh my product new, i love my reciver when it works I'm convinced the product is built like everything else these days cheap with no pride, designed to malfunction so hard working Americans like myself pull out of pocket to replace the product being a different brand or what, cuz large corporations repeatedly screw the little man time and time again for years and believe me folks it's only gonna get worse if the little man sits back and does nothing.. I personally do NOT recommend this product costumer service with this product also burns my as# it's a waste of time on your behalf.. Thanks for reading hope to hear from many of you.
