Re: TV has power but no picture.
If you know how to read a schematic diagram and have the proper tools then you should be able to fix the set. The first thing and most common for your symptom is a bad regulator IC in the main power supply It will be standind up on a heat sink and start with STR and have 4 numbers after it. Now it could also be a problem in the sweep circuit but not to many faklures there. I have seen once that a blow audio output IC shorting out cause the entire set to shut down and it did take out the regulator IC with it Too. A shop repair for a set like this can run around 250 all the way up to 500 bucks depending on what the fault is. Hope this helps ya. Good Luck

You most likely have a burn in on the surface of one of the picture tubes. What you need to do to confirm this, would be to take off the front screen, and with the set turned on, look directly into each one of the lenses, and see if you see a mark on the green or the blue tube. if this is the case, and I am pretty sure it is, the picture tube will need to be replaced, but this set is not a young thing, as the green faint lines is most likely a bad capacitor in the screen drive circuit. If the picture tube is indeed burned on the surface, most likely be better off buying a new TV set. Good Luck
