I'd say you have a faulty AS-15G ic on the T=Con board.

Thank for all the replies,

You are all right that the problem was in the t-con, using a x10 magnification lens I found a cold solder around the as15g chip. This was the cause of washout picture at cold start.

Thank you for pointing out where to start troubleshoting this problem. It is now working fine after resoldering the cold areas.

Tnx,

Mike
