Have you tried the a / v inputs?? If they work,might be a bad tuner.If they don't work,then your symptom is no video-no audio=
power supply problem? Check all voltages....T.

The flashing LED is an indication code of a board problem. If the TV is shutting down after a very short period of time, it is an indication the something is heating up. To isolate the problem, you will need to purchase some freeze spray ( component cooler ) at your local electronic shop. turn the tv on and spray an area ( usall about 1/4 of the board at a time ) and try to isolate the bad part ( component ). By repeating this process after a bit of time, you should find the part thats bad when you cool the part and the set stays on until the part heats up again. Then simply replace the part and your good to go. Always use precautions when working inside a tv as the picture tube can have as much as 35,000 volts on it ( can cause bodly harm or death ). DON'T COME IN CONTACT WITH THE WIRE OR GET CLOSE.
Good luck and I hope this has helped

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.

My Sansui SV2918 has vertical collapse and no sound.Please help.


Sansui.. Funai made?? Most Funai sets are identical. Find a diagram for a similar TV. Or.. Google the part# of the output IC. The datasheet should contain application data, including a basic schematic of the vertical cicuit.

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.




Let me know what you find or needs further assistance.

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.
