SOURCE: my videocon colour tv is

Hello
Ten years old Videocon TVs are fitted with Toshiba kit. Just desolder out the LOT from the board and go for a new one, with that old LOT as a sample with you. It is very difficult to give you the exact LOT number, as you haven't had the model number of it. Anyway, it will be available in the local market. OK.

Check its speaker/s first. Check whether the audio is muted or not. If all are OK, check and replace damaged component/s at its audio output section circuit. If you wish to get some details, check the site linked here. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

Trinitron sony model KV-27FV17 tv will not come on it is in standby mode


usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ..but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective ............... so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 ( US$ 12) ........iam from bangalore (09986222774, [email protected] ) .....i don't have any idea about EHT component's price & service charge in your area........this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other tools...so my suggestion call TV service engineer or contact sony service centre.........

Sony kv 32hs500 after blinking does not work.it makes a ticks noise and after 7 blinking does not turn on.


1st POSSIBILITY - usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ( in some TVs ''garrrr'' like sound comes - but it is rare) ..... but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective

2nd POSSIBILITY - main capacitor (very big in size) is blowing off


i think in your case main capacitor is blown

- so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 (US$ 12) & price of capacitor will be between Rs.50 (US$1 ) to Rs.150 (US$3)

- iam service engineer (computers, laptops, printers,etc) - bangalore - domlur - 09986222774 - [email protected] - if you are in bangalore then you can call me for service


I think you are in america/australia...side ----------- i don't have any idea about EHT transformer's price & service charge in your place..............

No Display, no sound- not working, showing dead. But input Power is ok. Picture tube filamment not getting power. model sony KV-2192M3


Hello
Check the input fuse first. If it is blown, there will be some short inside the power regulator circuit. Usually Sony sets uses STR regulated power supply. You can see this STR, and Ic, screwed onto a heatsink. Replace it with a same type and number. Before replacing the STR, check the diodes used in that section for damage, mainlu zener diodes. They might get shorted along the blowing of the STR. Check that section throughly before resoldering the new STR.
If any further assistance you needs, get me through Fixya. Ok.

My SONY tv KV-XF21M80 produces a continuous sparking sound


The tech is very likely correct. The EHT or flyback transformer can develop hairline cracks that allow leakage of high voltage that exists in this circuit. There are other related components that can also cause this, but the transformer is the most likely. This area in the set also builds up allot of dust also due to the high voltages and this aggravates the issue. I do not recommend operating the set very long this way as it may begin arcing inside and cause more components to fail. Replacing the part would depend on how much you want to invest in the unit. Get an estimate and go from there. Good luck.

That model number is not correct. What is an EHT? Must mean HVT High voltage transformer. If this set is 26 inch or smaller replace it. If larger yes replace the transformer.
