Hello Terry, your Denon AVR 2808, is not compatible with HDMI 4K signals, only for HDMI type 1.3, HD signals You can use your TV to connect all HDMI 4K sources and send a fiber optic connection from the TV to the Denon to get the sound of the equipment connected to the TV Greetings Franco Dosil Hola Terry, tu Denon AVR 2808, no es compatible con se?ales HDMI 4K, solamente para se?ales HDMI tipo 1.3, HD Puedes usar tu TV para conectar todas las fuentes HDMI 4K y envias una conexion de fibra optica desde el TV, hacia el Denon para obtener el sonido de los equipos conectados en el televisor Saludos Franco Dosil https://www.denon.es/es/product/hometheater/avreceivers/avr2808 https://www.denon.co.uk/uk/product/hometheater/avreceivers/avr2808 https://ca.denon.com/ca/product/hometheater/receivers/avr2808ci?docname=avr-2808ci-om-e_102.pdf

Reset the amp to factory default may solve your problem. Download service AVR2312 to see how to do.

Any power amps able to connect to pre-out can be used and of course, choosing a power amp with large rating is better.

" "I have seen a manual I which it said that dc issue, do anyone know how to disable the power on fault checking" You cannot do this. Protection can only be kicked out when no dc is coming out from speaker terminals. This holds no mater whether differential and voltage amp are defected (leakage) or protect detection SMD transistor(s) is/are leaked. They act as a switch. Download X2100W service manual and enter debug mode to check if DC or ASO(over-current protect ) makes protect.

“My reomote sensor is not lit and I have no sound coming from speakers” For your symptom, not related to remote sensor but to digital decode board such as DIR,DSP and LPF. Download service manual and enter "debug mode" to locate defective circuit(s).

download AVE1907 service manual and check all voltages supplied to panel including (positive and negative voltages as well as an AC voltage. ). If they are correct, replace all capacitors located on this board.

Its possible you have a bad audio driver board that once it heats up starts causing that problem. Try taking to radio shop unless your good with electronics.

Download your av-amp model service manual to solve the problem.

https://manualsbrain.com/en/manuals/1094327/?page=8 Hi! I'm adding user manual, hope it will help.

“The switching from one source to another has sucked since day one.”Problem comes from front panel, switches, OR CPU switch control circuit.

“Denon AV 1801 doesnt appear to power up even though the screen comes up.”Screen lit up means CPU does not have any problem. Did it power up within 5 second? If yes, find out which protection is now working. “Also there is no sound output” May be DSP problem. Remember to download AVR1801 service manual to check protection and DSP problem.

“when up & down scan buttons pressed, just keeps scanning w/out finding station. it does lock into a station when manually scanned. need reset & if so, how?” Don't worry. Your amp is normal. Your situation happens to any denon, onkyo and yamaha av-amp always due to extremely sensitive tunning unit. No need to reset. Tune any wanted station by another radio and jot freq. down. Enter desired freq. into the av-amp and store it.

May be DSP problem enter debug mode to confirm. Download denon1709 service manual first.
