SOURCE: Vertical Black line on display
Rakesh, You have a "dual scan" panel, this is why the line only decends down the screen half-way. This could be a connection problem on the buffer board which causes loss of the drive signal only to that part of the display which it is connected to. The vertical address buffer will be located on the top rear of the display, use great caution in inspecting these cables and connectors. If the integrity of the cable and connector is good the panel itself may be bad due to the drive IC being located on the ribbon cable attached to the panel body. this is better known as COF or, chip-on-film technology. I hope this helps you. Good luck. Joe Weibel CustomElectronics.Org

Just want to let you know that the problem you are having is a bad X board. This board may not be available from Sony, because it is sold as part of the panel

Your set is servicable with proper troubleshooting. Normaly, the defective boards are swapped out to service these sets. This fault can be in the address decoder, or the display drive boards. It is also possible that the failure is in the display assembly itself.
My preference would be to give the set to the authorised service rep to have an estimate to deterine if the set is worth to service.
