Re: phillips 32pfl5522d/05 no video backlight working

I had an lg tv from around 2008 with a very similar problem, the backlight would turn on and it would play sound but it would either display no picture at all or picture with green lines on the right side. It ended up being a bad solder joint on a bga chip on the sub-tcon board. What i did to find the problem was to warm up each board that had a bga chip individually with a hairdryer and watch the display. This may not be your issue, but is worth a shot.
