RCA 8335 combo unit vcr not working

I have an RCA 8335 dvd/vcr combo. The dvd player works. The vcr is not working. I have power from the power supply to the main VCR board. On the main vcr board there is DU 83.... DU 83 is a zener diode. DU83 looks ok but the board is a little burnt right near it. I would like to replace it but I cannot see a value on it. Does anyone know the value of DU 83? Any other suggestions on what could be wrong with the board? thanks

If the diode was bad it would kill the dvd also.

DU 83 is on the vcr board, not the power supply board. The DVD still works, even without the VCR hooked up internally. The VCR really has nothing to do with the DVD operation, other than when you want to transfer video from it to the DVD. So the DU83 diode has nothing to do with the DVD operation.

After reading voltage at DU83 (diode intact on board and power to board), I found 4.76 volts on one side and .69 volts on the other. I beleive the diode is good. Please correct me if I am wrong.
