My 7 year old plasma just started displaying a vertical coloured lines recently, although the sound is still coming through ok. I would like to try and fix it as I cannot afford a new TV at the moment. I actually work as an electronics technician, but when it comes to plasma TV's I wouldn't know where to start. Does anyone have any ideas what might be wrong?
Here is a short video of what it is doing http://www.youtube.com/watch?v=R0YSjoeGc84

Thanks.

most common trouble comes from faulty capacitor, with even a little dent outward at the top of capacitor's will actually kill you plasma tv
