But after T-con replace it has no picture, but it has sound and white led light.Talk to supplier about possiblity of Bad t-con , he mentioned to me to replace encryption chip on new t-con board with original t-con board.Please advise what could be problem.
ANSWERS:
"Hi @vipulpal ,
Have you still got the old TCON board?
If so what happens when you put it back in, does the problem go back to what you originally had i.e vertical lines all over the place?
If so, here’s an and image from the service manual showing the troubleshooting flowchart for a No Picture problem.

Since you have replaced the TCON and it didn’t work (see p.A1 about encryption) it may be a mainboard problem or worse a panel problem."
