I would do the same. New technology is obsolete in just a few years and it is cheaper to manufacture products that are not repairable. Goods are now considered obsolete when it is no longer profitable to support them. Replacement picture tubes now cost more than a new set and don't last as long as ones built 10 to 20 years ago. Fewer after-market vendors, and more specialized and proprietary parts add to the problem.
Generics are almost unknown.
Manufacturers like Sony just keep raising the price of repair parts until no one can afford to get anything fixed. Many people don't like the hopelessly complicated TV sets and VCRs of today, but that's all you can find in the stores. U.S. manufacturers were required to maintain a repair parts stock for seven years. Almost from the beginning, the Japanese ignored that restriction and they were not forced to abide by our laws. We couldn't remain competative, and now there are no American manufacturers of TV sets.
