A number of things can cause that problem in that television.
1. horizontal output blown/ short circuit.
2. Bad capacitor on the main B+ line.
3. shorting flyback transformer.
for first and third television will try to start up but shut down causing lite to blink power supply will also make high pitch sound about every second.
in case of the second power supply sound may be much faster.
