I have a sony wega trinitron, model KV-32FV15.It takes a while to power on, and when it does, the picture flashes on and off - about a second on, and the one second black screen. This problem started about 2 to 3 weeks ago with just a longer power on process, then the picture flashing on and off a few times until today, when it does it all the time. Can anyone give me a clue to what could be wrong and what parts I would need replaced? Sony technician seemed to think it was the lamp that needed replacing...
