The front panel is telling you one of the power modules is probably bad. Not an DIY type of repair. These parts are near $40.00, plus cost of replacing.
Look at options to replace your trusted receiver with a new one.

Please respond to my effort to provide you with the best possible solution by using the "Acceptable Solution" and/or the "Helpful" buttons when the answer has proven to be helpful.
