Thank you for your response. Can you try this steps.

1. Unplug the receiver's power cord from the wall and leave unplugged for at least 30 minutes. Remove all speaker and audio cables from the back of the receiver while waiting.
2. Reconnect the power cord after at least after 30 minutes has passed. Leave the speaker and audio cables disconnected.
3. Turn the receiver on and turn the volume to the maximum setting. Leave the receiver on for 30 seconds. If the receiver shuts off and goes back into protect mode there is an issue with the receiver. But if the receiver will not go back to protection mode then you are good.

Can you post the picture of your reciever on this page please.

Do you have a cable button on your reciever?

Do you have a tuning mode button on your reciever?

Give me a second.

Just a question. Your receiver is not making any sounds in any mode correct? And external speakers are all connected properly.

Can you try this, while holding down the Tape1/Video botton then press and hold the power button until the unit shows Clear on the screen or until the receiver shuts down. Then if the Clear disappear on the screen or the unit shuts down power it on again.

Or double check the A and B speakers button as well make sure its on.

Standing by for your updates.

There is a Tape1/Video botton right below the lcd display hold that down. While holding that down press and hold as well the power button. See if you will see a Clear word display on the lcd or if the device will shutdown itself. See if that works.

And also I see there is a Mute/Mode button there try to press it a couple of times it maybe on mute.

Do you still have the user manual with you?

Can you try this. Press and hold the Tape 1 and the speak a button until you see the clear and it shuts down. Then power it on again. Tell me if this will work. Will be standing by.

If you still have the user manual with you it will show it on page 12 on how to troubleshoot the reciever. What I can provide you is only the service manual for this reciever since the user manual you need to download it and you need to pay for it. I can provide you the link where you can download the user manual.
