My father has a 5 year old JVC 27" CRT TV. He just told me that the picture has recently started to become darker and darker. He says he has to turn the brightness control all the way up to see the picture. 5 years doesn't seem to be a very old TV to me. He will have it checked out by the retailer (Bleeker TV in Ottawa) but I need another opinion. Is this the picture tube failing? He bought it for $279 Cdn and I'd hate to have to tell him that he probably won't find another CRT in the city and that he's going to have to spend at least $600 for an LCD HD TV (26"). Thanks.
