SOURCE: sansui sv2918 keeps blowing k2996 mosfet. Power led flashes and ta-ta-ta sound is heard

Check the Flyback Transformer

and associated circuits.

If 2SK2996 is blown, it may take out the PWM IC and some components

that goes with it.

I have a sansui tv model sv2918,it doesn't play

The TV has some firmware defect. Seek tech support.
Unplug it from AC mains wall socket, and plug it again after 5 minutes. This must make it a hard reset.

Powersupply Faulty

Check for short circuit on your Powersupply. If you can isolate it, much better. check the voltage regulator if it supplies power to the system. better still check the regulator itself.
