it sounds like you have horizontal colapse a very complect repair try hitting the tv if the screen comes up full picture then its a dry joint if not there is an ic or power fault toss it
this is a frame fault
the fact that you can still see the line when the tv is off is because you have been watching with the line and it has burnt into the crt.
You would need to replace the flyback on this and your looking aroung $65 parts and $85 labor to shore this problem up. We can recommend you a repair shop or you can purchase a new TV its all up to you
sounds like you may have a bad ic it probley is a surface mount on the bottom of the board it could couse this problem would need to take to a shop to repair. The ic probley is numbered ic101 on board.
If the horizontal lines going through the picture are fine white lines, then I would suspect the picture tube as having a heater to cathode short or some other problem. Since some sets have had a 3 year warranty on the picture tube, you may be lucky unless the labor to replace the tube is more than the set is worth. Sanyo is usually not a good name in consumer electronics anymore, so if you're looking for a replacement I would look elsewhere.
Set starts, horizontal and vertical deflection work, HT ok, crt heaters ok, but no sound or picture
I turned the G2 voltage up and noticed a white screen with flyback
lines, frame ok. I detected two badly soldered double diode rectifiers
