Did just a base recap of the set, not including the filters. No change. No vertical sweep....the 6GF7 is still dark, and that's the key to the whole issue here I think.
Now, since I don't know what this set is and nobody else does either with any certainty, suggestions as to where I should go from here? I can do the filters, I just don't feel like it if that won't cure the issue
Normally right about now I'd start testing chassis voltages, but God only knows what this TV even IS to try to get a schematic for it.
