    If only one vertical line appears on the screen, this means vertical section is working, and the defected lies in the horizontal section. Check horizontal deflection coil, it may be open.

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.

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.

Emerson tv model no. ewf2704


Hi: When you say small horizontal screen, ¿Do you mean picture does not fill the screen completely from top to button? ¿Do images display normally though they are smaller in size? ¿Is color and definition of signal OK? Please answer so I can have a better picture of the problem.
