My Zenith Model SG2037W has lost its picture. Sound is fine. Don't see any
glow from the neck of the picture tube. There is a burn mark on one of the
wires leading to the circuit board mounted to the neck of the picture tube.
The burn is evidently because the wire was lying against the high voltage
lead which has a corresponding burn mark. Does anyone have a schematic of
this set they could lend me?
