The tubes have a useful life of 3000 hours. Replacing those tubes is close to $3000.00. It's going to be cheaper to get a smart flatscreen TV. The minute you try to clean the mirror, you will put tiny scratches on it. There is no bulb in tour TV, There are 3 cathode ray tubes. There is a lot of high voltage (25,00 or more) inside the TV, so be careful poking around inside the TV.
