Have you tried running it with just one ribbon connected to the panel to see what the half picture looks like and then switch off, reconnect, and repeat with the other ribbon.

Yes friend i have tried that but no changes. I have replaced AS15F just to be shure but also nothing happened.
It looks like there are two problems not only one. Very strange situation.

Normally you don't see this issue with SONYs...You would see this more with SHARPs.....From what I have researched.....there are some resistors on the T-CON that need to be repositioned...I'm not sure which ones......the T-CON's EEPROM software has been corrupted some how....Easiest fix for me would be to replace the T-CON with an exact replacement.

Thanks for reply, yes it would be easiest to replace t-con and see what is happening, but i dont have it at the moment.
I have tried to make changes in Service Menu but no changes in picture.
But i will try to connect t-con to another main board just to eliminate main board as problem.

There is an eeprom on the T-CON Bd...that is the one I refer too.
