If the channel are constantly changing then you have bad channel switch inside the set. The switch is located just behind the channel up or down (depending on which direction the channel are going). I have fixed them before by taking the back off and squirting with WD40 to loosen them up. However, the best fix it to replace. They are called tact switches and there are many different kinds in different TV's You would have to have the exact replacement. Has to be unsoldered the old and solder in the new. I recommend changing all of them including the Volume + and _ and the others as well. Do a search online for electronic parts and you will find a supplier.

No heater for tv model no.SV2918


Check the continuity of the CRT heater [pin 1~8]. If it is found open, no need to proceed. If it has continuity, check the AC voltage there when the LOT works. Should have about 6.2VAC. If not, check all the solder terminals and series resisotr. connected to this bus. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

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.

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.
