    Either the CRT had a catastrophic failure, which is very rare unless it was dropped, the high voltage anode attached to the CRT fell off (easily fixed by a professional, and again really rare) or a component in the power supply failed. The latter can be repaired inexpensively by a TV shop, but a broken CRT is the end of your TV.

    Carefully rock the TV back and forth with it unplugged, and/or turn it upside down and rock it just in case a foreign object fell through the top vent and caused a short.

    Do not attempt to open a TV and work on it unless you know exactly what you are doing. There are high voltage capacitors that can seriously hurt if you touch the wrong thing.
