You may have one of two problems. A vertical one in which you may have horizontal lines across the top of the screen. Or one bright centered horizontal line. The fix here is to resolder the vertical IC and replace the capacitors near and next to the vertical IC. The second problem would be the dead set. In this case , the power supply will need reworked. You will need the following components. Replace the powerline regulator STR53041, the regulator N4923 and capacitors of these values, 25 volt at 100 MF and a 35 volt 22 Mf. these components are near and next to the regulator STR 53041. Now,next to or in front of the flyback transformer there is a small cap at high voltage...I believe this one may be a 200 volt at 1 or 2.2 Mf. replace this, and the other capacitor near two heat sinks on the edge of the board in front of the vertical IC is a 25 volt 220 Mf cap that is also dead. It has been a very longtime since I have repaired this one. But the information, will get your TV up and running again! Find an electronic hobbiest or a TV tech to repair this for you. This info will help you get a reasonable repair bill. Thanks for asking and show a few hands of support.
