(FWIW, I got into the repair biz 55 yrs ago, haven't done it in a while. My hat's off to today's guys who have to handle these incredibly complex machines!)
Anyway, recently got a (new) RCA DVD player chassis-only for the ATC221. It powers up and all voltages seem to be there.
Question is can the player be operated as a stand-alone device or are there problems such as the keypress scancode source being off-chassis? Any jumpers needed?
Any hints appeciated.
