Question about Sony FD Trinitron WEGA KV-30HS420 30" TV

1 Answer

I have a SONY KV30HS420 after off over night will not power up

The sound will come up for a few seconds the led on front blinks 6 or 7 times, then shuts off. After turning it on several times, you can hear the High Voltage come up and it works fine. If you turn it off then back on, it also works fine. It just will not power on after the unit has been off several hours.
It is NOT a cold solder joint or loose connection.

ANY IDEAS?

Red light is blinking 6 times


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
Type in the brand name and type of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

I have a sony model KV30HS420. The hv comes up for a second the the set shuts down with 6 blinks. Any ideas? thanks.


The Horizontal stage has stopped. It could be caused by excessive EHT and the set will shut down, the power supply is faulty or something more sinnister like an electrical leak on the output side of the EHT unit.

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

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.
