Does anyone know why I have a blank and blue screen on my Philips VCR- DVD player? I can record..but I don't get the TV picture while my VCR is on...the screen is just completely blank..and there is no sound either. We have a Samsung HD wall TV...and Cox Cable. I get L1...L2...DISC..and just a little flash of the TV before it goes blank again..Once the VCR is off again the TV picture is fine again.
