This does have simulated wood grain on the front and sides, and it has an early version of the veractor tuner in it (the one where you had to set each individual button which from my understanding that kind of tuner came out in the late 1970s).
Anyways the power supply in this unit consists of a giant power transformer (cold chassis not hot surprisingly enough) and a small circuit board with a large 1/4" fuse soldered to it and some capacitors and resistors, and that's it.
Not sure how I would go about servicing the power supply in this unit because the power supply board does come out but you have to remove the top and bottom panels and then remove the cover from the back that covers the power supply input (the place where the power plug goes into the cabinet), and then removing two screws from the power supply board and then lifting the power supply board out of the cabinet. Anyways which electrolytic capacitors are going to be the ones that will be bad? Any specific values to look out for that will be bad?
EDIT: I found the rest of the power supply circuit, the part of the power supply circuit I was seeing was only part of it, anyways there was a removeable 3A fuse in the other part of the power supply and it was blown so I replaced it with a 4A fuse and its working fine now. So yeah it seems that maybe a power surge must of taken out the fuse because there's no signs of any burn marks anywhere on the VCR.
OK so I got the "No Power" issue figured out, now I need to figure out the "no rewind or fast forward" issue, also it seems that when you hit play it acts like its trying to load the tape into the mechanism but the take-up and supply reels don't move thus not loading the tape into the mechanism for it to play, when I hit the Rew. and FF. buttons all I hear is a solenoid click and that's it, its for some reason its not activating the motor that drives the supply and take-up reels, it's almost as if the motor for the supply and take-up reels is seized up or dead... which I hope isn't the case because then that means this VCR is beyond repair because I'm guessing that the motor is NLA.
