It doesn't play the disc, when I put the disc in it reads, then play appears on the screen and the motor stops working, the VHS works normally. The client indicates that by mistake he placed the plug at 220v and it no longer turned on. After checking, I found the blown fuse, changed the fuse and that's it.

SONY KV-2170B
+b com 200v This device arrived in my hands with the converters q602 and 603 (2sc 4034e) and the zener diode d613 (r2m) shorted. After exchanging these components and without observing any other components with apparent problems, I turned on the device and the r2m diode shorted again. Removing it from the circuit I verified that the +b voltage reached 200v, when normal is 125v. After several hours of measurements I verified that the resistor r618 (100k x 1/8w) was open. went to change and run for the hug. Paulorusso
