OK, line voltage is 117 coming out of the Iso Transformer with the set running, normal line voltage here is about 125v.

The 135v test point has 127v, not far off considering the low input voltage.

I pulled the regulator, not shorted, two legs check like a diode more or less, infinity one way, some resistance the other, the other two legs read pretty much infinity or at least in the megs.

The Flyback has some test points and marked voltage points too, the 135 is running 127 there also, there is a TP for 200v, I read 125 there, a 24v TP has zero but I don't know if I'm measuring from the correct point (chassis ground).

Also, hooked up a DVD player but couldn't get it to receive anything, tuner tunes up and down, picture flickers a bit when it jumps to UHF but no picture at all.

Also, no sound, no white noise, not a peep from the speaker even at full volume.

I'm starting to think maybe there's an open somewhere killing a voltage needed for these functions?

There are two fuses, both OK. Soldering looks good underneath.
