Blank screen


Any error message about inputs? Maybe that clicking sound happens when iit connects to the selected input, but nothing is connected. Can you scroll thru all the inputs? If so, turn on any devices connected to the JVC and scroll thru each input to find the one you're looking for.

Rca tv... screen is black when you turn it on but it will show the Menu and let you go thru the menu... It also says tv is muted and wont let you turn the tv up


In the menu see if you change the input selection to something you know is on (a cable box, DVD player) and make sure that is the input picked.

HDMI signal cuts out for a few seconds constantly from receiver to television. It does it when switched to cable box and the roku box. Onkyo TX-SR606 Scientific Atlanta Cable box thru HDMI Roku Box...


Mine did the same thing where the screen would go black for a few seconds and then the picture and sound came back. I would try (1) switch HDMI cables, (2) try a different HDMI input in the back of the receiver, (3) try different input in the back of the TV. None of these seemed to work with mine. I finally ended up running the cable box direct to the TV and only run the audio through the reciever via coax or digital. No more problems. I think the HDMI inputs in the back of the reciever have a problem continuously carrying the signal if it is the leaset bit weak.

Flat screen to dvd connection help!


It depends on the TV.

On my Phillips TV this is switchable via the TV setup menu, and you get no sound with HDMI unless you change that setting.

The reason it's switchable is that the HDMI input is usually common with one of the component-video inputs (AV3 on mine). (cost saving move)

Thus if the menu is set to hdmi, then the audio goes thru hdmi. If it's set to 'component' then it goes thru the RCA patch cable.

Can not change "Device" input, no sound control,no remote control


I unplugged the manual switch electrical connection. Everything works just fine with the remote.
Not sure what is wrong with the switches just yet, but suspect a resistor problem. I have checked all voltages and have 5.04 v feeding the switch assembly on what I feel are the correct circuits
(5v, ksco, ksc1, man/reset). I have no voltage on the ground circuit with the board plugged in, so the ground circuit should be ok. I have tested all switches with ohmmeter, all switches work. I suspect a resistor problem as I have one with no voltage drop and one resistor with no voltage pass-thru. Would need a wiring schematic with values to pinpoint better.
