Sounds like inverter board. What it sounds like is happing is your LCDis working ut the backligkt board that allows you to see is kickingoff. (as you still have sound) Which could be the (most likely)inverter board, or the power supply board. You can take apart and checkfor voltage at your power supply. The power supply has a pigtail withlarge white wires and a connector. Power up with the center back coveroff and check your voltage at the white connector on the power supplybefore and after the screen gos out. If there is no large voltage lossit is your inverter board.

Verticle lines on screen


This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
