My sony wega kv-36 tries to power on. the stand by light blinks 6 times every time I try to turn it on. After turning on and off like 50 times, I seem to get lucky and it actually powers on and woks...


The Power/High Voltage board is the main cause of this. Most of these boards must be sent to Sony to be refurbished because Sony no longer manufactures the board.
I hope this helps,

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 kp-61hs30 has no power. no blinking


Check fuses on power/delection board. Besides normal looking fuses there are micro fuses that are small and are yellow or blue in colour

My TV is just bliking its power indicator and automatically off.


Sounds like a power supply problem. Depending on the Sony model, the blinking may be a diagnostic code to indicate the specific problem. It is most likely this:
3 Blinks = B+ over voltage protect
Sony sells the service manuals for their TVs and you should be able to find this info out for sure. My recommendation is to buy a new tv.

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.

1 Answer

No power.


Usually, in those Sony sets, a crack developes on a small transformer in the horizontal drive circuit, which causes the horizontal output transistor to short. This immediately shorts out the switching transistors in the power supply and blows the Sony 0.1 ohm resistor fuse. A shorted flyback (high voltage) transformer will also have the same result. The power supply does NOT need to be replaced. The parts should be replaced, the flyback checked and the board resoldered by a qualified tech familiar with Sony sets.
