Did you verify that you have the DCV on both end of the fuse on the TCon board to make sure it has Voltage to run the Tcon?

Yed Idid, I have 12Vdc after fuse on T-con, and the voltage regulators are working on T-con.

How many ribbon cables foes it have between TCon and the LCD panel, two? If there are two, then try having one connected at a time to see what you will get on the screen.
