i'd take the frame off and power the tv up and touch the ribbons see if the  yellow line goes, if it does go then you have a faulty screen u can bond rubber on the ribbon stop it flexing, but this only a temporary repair. it may give the tv a few months more use good luck

Check the picture on another tv using AV Out sockets on the Sony. A normal picture on the monitor will generally rule out the main board. This model also has built-in test patterns to check the panel. If the patterns have the same band, panel is faulty. You have to access the test patterns in the service menu.
