Eric, I've got the same model of TV, and have developed exactly the same problem in the last few days. brightly coloured vertical lines when you switch on - so far this has cleared up after about 30 min of warming up, and if you keep switching off and on it goes away eventually, but its not fixed. I see there is also a 26PF3320 on Ebay at the moment that is exactly the same, going for £40 - is this yours? if not thats three with exactly the same problem. I don't know how to fix this as such, but maybe we should stay in touch if its an inherent problem with this model.
