Hello,
Today I acquired a Sony HCD-C770 5 disc DVD changer/mini amp that is non-functional. When I power it up, the standby light just flashes repeatedly and the machine refuses to do anything.
Upon checking the internet, I found forum threads discussing a certain electrolytic capacitor that...
my sony sr700hp dvd player has no power..
I opened it and check output voltage.no voltage found
primary section looks fine...its on tny176pn ic(u1).
no shorts found.
I changed u2 and u3(tl431) by guessing.
no result.
what could be the problem?
thank you!
