Sony Dvd player power supply problem
my dvd player isn't turning on..so I open it and checked in power supply for output voltage and I didn't find any voltage in output segments.its build on tny176pn ic.
I started with fuse which is ok..than for any open diodes and found none..I checked the opticoupler for little voltage which I expected and there's none.
I measure the tny176pn ic's en pin and also no voltage.
so what should I go for??
Es esta una buena pregunta?
