I have a TAC0051 that has no video. It powers on, but no video and no
vert out.
I ordered the service man. for the TV (FOX Intl) and received a CD Rom
that contains several schematics, but not the schematic for the 50A50.
The 50A50 service manual cover page and one parts page was all that
was on CD for 50A50.
The B+ on the horiz. out is 150VDC, with a horiz waveform of approx
1400 volts p-p on o-scope. The B+ on the vert out IC is approx.
16VDC. (Should be 33VDC?)
I suspect the problem is in the power supply, B+ too high on the horiz
out, and B+ too low on the vert out IC.
Could someone point me in the right direction, or possibly even e-mail
a copy of deflection and signal schematics for this tv?
Thank you,
Jerry Murray
