Hello, most common faults, such as CRT TV will not turn on. The reason stems from the low power supply failure, or from the high power supply. There are two transformers suppliers, with more common high-tension transformer goes bad. Price of 80 or $ 100, sounds reasonable replacement of transformer. Along with this need to perform some tests that require a professional, to confirm that the problem is due because of transformer. One test is to test basic stability, voltage power reaching the high-voltage transformer. If lower than normal voltage. Then perform the same test, when you break the initial snap of the transformer. If the voltage rises to the desired level must be to replace the high voltage transformer. Good luck!
