SONY KV-29FS140
BX1L 		It does not turn on, the opto, ic regulator of the supply, 36v zener was changed. According to the diagram, the two capacitors, I already get voltage in the secondary, in the +b it outputs 50v. The 3.3 plus 1.8 appears but the 12v does not appear. What I have noticed is that tsound is a voltage fluctuation between 11v-15v in the primary, if you could help me I would appreciate it. The power IC was found, a 1k resistor, the opt, and a burnt zener. This email address is being protected from spambots. You need JavaScript enabled to view it.

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.
