I have a 15 year old 32 inch Sony Trinitron model KV-32S16 color TV.
When I first turn tv on there is pyramid shape of light blue and red. After about 10 minutes the picture starts coming up from bottom of screen. The picture gradually continues to increase until after 20 minutes it fills the screen. I think it is a board but I don't know which one. Thanks
