Question about Denon AVR 2808Ci Receiver
Regarding Denon AVR-2808CI When I turn on my receiver, it automatically turns off and the power button flashes red. The display on the receiver prior to turning off says "Tuner Ext. In" Any thoughts on how I can fix this?
Protection circuit turns off the unit because of critical conditions- wrong power supply voltages or one of the power amplifier channels is bad. First, visual inspect the power amp board near the heat sink for burned resistors, test outputs for a short. If there are no problem you may try to turn the unit on and you have several second before it shuts down to check power supply voltages and power amp output voltages and bias, then ... Long story you'd better take it to a repair shop or repair at ebcelectronics.com
