If so I'd get estimates but no shop tends to go near such an old set.
If you are an electronics tech that knows about the LETHAL voltages inside, I'd start with unplugging and re-plugging all internal connections. I do not suggest repair on over decade old TVs today.
My Sony Bravia KDL-40Z4100 is experiencing intermittent image problems. The picture becomes obscured with flashing vertical lines that vary in intensity. The problem comes and goes. Its been happening for about six months now. Used to last for 15 minutes before normal picture returned. Seems to be getting worse now. Whats wrong / how do I fix?
