Pictures of the T-CON board?
You will need the Oscilloscope to see if you are getting any signals at all on the LVDS connector.

Hi,thanks for quick reply.There is TV board pictures.
I don't have the Oscilloscope,is there other way to diagnose the boards?

using a oscilloscope and check the LVDS signal from the main board is the only way I know how to make sure that the main board is putting a signal out. Other than that, I'd say you have a T-Con problem. If you want to make sure it isn't the main board, you have to borrow an oscilloscope.
