started with vertical stripes then no picture at all.

I'm having basically the same issue as Colin B.

My tv started with vertical stripes then no picture at all.

I replaced the t-con board and got the vertical stripes back again (still no picture).

Next I replaced the main board and had the stripes for a few minutes then back to the blank screen.

I also installed a new power board before the new t-con board. I borrowed the power board from this tv to fix another tv. That tv was an easy fix!

I've checked all of the connecttions, cables and wiring and it all looks good.

I've also tried isolated have of the screen and nothing changes.

All of the back lights are working properly.
