Samsung LN46A650A1FXZA vertical line come and go

[MAD hATTER]

OK First off the vertical lines are spaced about 1 1/2 " apart and when the picture changes they sometimes shadow across like blinds on a window.
First thing I trying was unplugging all connectors took the main board out and checked for anything out of the norm, Put it back together and everything worked great for 3 days.
Then it started again.
Now it will show up and then disappear for a few seconds sometimes longer and when the picture changes it comes back.
I tried a different T-Con board, pluged it in and had sound but lost the picture. Put the old board back in and everything is back with lines but at least te picture came back.
Since then put a new main board in same result no change.
My question is do you think there is anything in the power supply that would cause this? Or should I try another T-Con board. May have just got a bad one.
Thanks

I would say the replacement tcon is bad. Your original one is defective.

Check the fuse on your replacement tcon. Is it good?

Thanks for the reply.
The replacement was under warranty and has been sent back. They didn't have any more in stock.
Just wanted to make sure it was the T-Con before I try to get another one somewhere else.
Thanks
