SOURCE: SONY KV-32S25 TV SHUT OFF...NO POWER NO SOUND

You have a blown fuse. It should be a GMA7 amp or a 5 amp. You could try to replace it and see if your TV works again. If it blows the fuse again, then there is something shorted causing the fuse to blow. Then call a good TV Tech.

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.

Sony KV 27FS16 TV does not power on


The chirping is the power supply trying to start. This is not a repair that I would recommend a novice attempt. PLease have this unti serviced. Expect a parts cost in the $20-$40 range for power supply caps.

No Power Problem with KV-27s15 Sony TV


Barry, remove the back cover by removing the screws with an arrow next to them. The fuse is located on the left side as viewed from the back, where the power cord connects to the circuit board.

Accroding to your model number:(KV-...) In sony tv units power supply porblems is very low unless a power surge.
You have to check these things.
1. Stand by 5V available or not
2.If stand by 5V available press power and check B+ is getting or not
3.If B+ available check Horzontal oscillation
4.May be H-out transistor or video amplifier is bad.

SONY TV WON'T POWER UP WHEN COLD.


as there is a problem of any electrolytic cap in tv as per what you say. but in my opinion it might be taking time to crt glow due to low supply or its ageing.
