turn (only by 2 to 5 degrees ) all the knobs on flyback transformer in clockwise direction & then switch on tv .............you will get picture atleast for 1 or 2 mins ............ this confirms only flyback transformer is defective ........ so it has to be replaced by new one .................otherwise transistor (big in size fixed near flyback with its back clamped or screewed to aluminium metal ) has to be checked ......if that is also fine then complete main board has to be checked ...... but flyback replacement is a must ........in your case iam 100 % sure only flyback is deffective ...........vishnuswamy_26.jpg

You have a power supply problem.
The microprocessor has its own supply and is not receiving a "hand shake" from the line output stage that in turn is not receiving and power from the power supply.
The chopper transistor will possibly be short circuit taking the feed resistor with it.
Check for dry joints everywhere and MAKE CERTAIN THE HT CAPACITOR HAS DISCHARGED!!!!!
Hope this helps.

Screen will not turn on, power light flashes red. Nothing happens when power button is pushed will not turn set off.


try checking first your tact switch or your power button, then next look for open fuses or low ohm resistor on secondary part of your power supply then check your horizontal and vertical outputs for shortage and open circuits check also your horizontal drive stage.

Kv-32s120 standby LED blinking no sound or picture


How many times does the timer light flash between pauses?

1 Answer

Power button Flashes


For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.
Thanks,

Tv won't turn on?


The main power supply section is not working.
(standby supply is OK)
Common possibilities are:
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.

the problem in power supply. if its output is ok than you will have to check horizontal section.

No Picture, No Sound...Please Help


The most common problem this set has is the Horizontal Output shorting, usually caused by the High Voltage transformer drawing to much current. Whether it's the high voltage circuit or the power supply, having a tech look at this set would not be cost effective. Start looking at the newer technology. Hope this helped.

TV won't turn on


Is a good thing you have an indication of power,it means some volts supplies are working ,your set might have a shorted output transistor and he is the responsible for lighting up the picture tube and energize a transformer that also provides voltage supplies,if the transistor is bad it has likely open the safety resistor that gives him the power to operate.If you are familiar with tv service you can check this part to start but if you are not too familar with tv service be safe and call for the assistance of a servicer.
