The right hand third of the screen of my Bravia has developed vertical lines and discolouration. Have checked aerial and connections and all are fine. Any suggestions? TV is 6 years old. Thanks!
It appears that your TV has developed a hardware fault. The first port of call would be to contact an authorised Sony Repair Centre to get this fault diagnosed and repaired - see link below
However doing a quick search around, it appears you are not the only one that has this fault (links below). Unfortunately I dont have the time at the moment to go though all the theads, but it seems that the Timing Control Board needs replacing.
