Got the board today freak.

Hooked it up and just connected the right side ribbon cable.
Wife said it had some horizontal lines and vertical lines on both sides of the TV. Mostly the right side.

Tcon blew. I had it connected for 2 seconds. Literally 2 seconds.

So yeah. Big day.

Dammit. That sucks! Your right side is for sure bad. If you feel up to it order that transistor I replaced. Bet that's all that blew. Then connect only the left side leaving the right side side ribbons disconnected from the bottom boards. Bet it stays on.

I got some transistors and some dc to dc converters coming from China.
I'll let you know what happens when they show up.

Ok so here's the deal.
I repaired all the tcons
Tested each one for proper voltage.

When I connect the ribbon cable going to the right side of the TV I get some white flashes and horizontal lines.
When I connect the ribbon cable going to the left side nothing.
If I disconnect the ribbon cable on the left side that joins the two horizontal gate driver panels together the left side of the screen goes white and stays white even without a tcon connected.

I'm not sure what my next move should be.
Do I remove the left or right side gate drivers???

Read carefully and give me an opinion please.

Never mind.
It had at least one blown vertical gate driver and probably some horizontal ones as well.
Oh well.
I'm going to use it as a desk light and hang it above my bench. No joke.

Oh man that does suck. I'm sorry..we gave it a valiant effort thou.   When a vertical gate driver fails it's game over.

Oh well. Like the idea of a desk light. I did this with a 39 inch samsung led that had a cracked screen. Works well.. at least you'll get some use out of the damn thing since it's been so stubborn. Give it hell lol
