Back in the days when all you had to do was replace a tube, it made sense to repair TVs. But, now, there are always changing technologies improved circuitry, and components, so there isn't a vast storehouse of older parts that won't fit into a newer models. Plus you aren't replacing one tube, but a whole complex part, and paying a guy to come to your home, and spend time figuring out what's wrong, then ordering the part, picking it, and installing it back into your TV. Granted that may be cheaper than getting a new TV, but there is no guarantee your old TV is in fact getting old,, and may be on it's last legs anyway. TVs used to be extremely expensive; but while , today, they're not cheap, you don't have to mortgage the kids to get one.
