Not a repair, but... nice big (circa 2000?) 25 inch TV has great picture when working, even sharper than the flatscreens I've seen, but annoyingly flickers / gets horizontal white line for 10 minutes when warming up. After warmup, all is well generally. Hoooked up a spare (even older) 20 inch TV that does not flicker, tried it out. Got all my cable channels! Yay. Then tried DVD. DVD played fine for an hour, then picture went blurry and sound remained. On the 25 inch TV, when that happened I would just change from channel 3 to 4, and the picture would clear up. Tried that trick on the spare 20 inch TV (by rotating old fashioned click knob) from 3 to 4, same blurry picture. (Sigh....)
