Hi,
I have an older zenith tv model# zb2777h
Does anyone have any schematics/service notes on this? I had called
zenith and they don't support that anymore and neither do the other
places that I have tried.
The problem is that the sound does not work. The amplifier seems
fine. I traced it back to the main power board that is not supplying
a low voltage for driving the ICs on the amp board. None of the
components seem fried and none of the fuses are blown. Everything
else seems to be fine.
Thanks.
Derek
