My small (13" CRT) Sony Trinitron, which was manufactured in 1996, just started acting up. When first tuned-on there is no picture and just static for sound. If I leave it on, I find that 5 to 15 minutes later the picture and sound are perfect What's up? Would it be costly to fix? And is it something that a do-it-yourselfer should attempt?
