Sony WEGA KV30HS420 shuts itself off

Actually we have had our TV since January 2005. Just in the past month it turns off by itself. We can turn it back on, but at the next commercial it turns off again. The weird thing is sometimes it can go an entire day without turning off, other times it turns off after the first 20 minutes and keeps turning off every 5-10 minutes. Picture is perfectly clear when it is on.

SOURCE: Sony FD Trinitron WEGA KV-24FS100 24" TV On/Off problems

I think I have the solution for you. I have the same tv and it does the same thing when you turn on the power button on the remote when the tv turns on you hear a click then the red light flashes about 5 to 6 times then the tv comes on. on the remote there should be two buttons on top of the remote one says power and the other one says system hit the power button to turn on the tv when you hear the click and see the red light flashing then hit the system button which will turn off the tv then hit the power button again and it will turn the tv on without the red light flashing it should work

Will only turn on for about 3 second with no picture and then turns off. Standby light blinks 6 times


For the KV30HS420, 6 blinks, pause, 6 blinks, etc. means "LOW +B OCP/OVP (overcurrent/overvoltage)" and the probable cause locations listed are as follows:

1. +5 line is overloaded (A, B, M boards)
2. +5 line is shorted (A, B, M boards)
3. IC504 is faulty (A board)


hope this helps John

Power turns off right away


Its correct, Sony is no more selling plasma and I think many companies has already shut plasma production and CRT TV as well.
All TV manufacturers are busy in LCD TVs.

Sony WEGA Large Projection TV


I sounds like the projection bulb has failed. I think there is a red lamp on the front that lights up when the bulb fails however.
This sounds very similiar to what mine did when the bulb failed about 2 months ago. Once the buld fails the TV will shut itself down and keep doing that until the bulb is replaced.

Sony KV30hs420 0 Stanby Light Timer Blinks 3 times and powers TV off


Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672. If you have electronic knowledge you may be able to fix it. Let me know if I could help you further.
Hope this helps.
