  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

    this is not a flat panel tv. this is a really heavy tv, had to buy the stand to go with it.

    Flat panel TV's don't use AKB and analogue video processing, tubed tV's do as it is part of the luma balancing system used by Sony.
    Hope this helps.

Sony FD Trinitron WEGA Won't Turn On


The key here is the count of the blinks. I'm assuming that the model number is KV-36FS120. Please post the blink count. It should be a count-pause-count...

Thanks,
Dan

TV will not come on.


The 7 blinks indicate a high voltage shutdown (high voltage exceeded 33,000V). This is usually caused by a defective regulator. Could you please post the exact model number (KVxxx) and I'll look up the part you will likely need?

Thanks,
Dan

20" Trinitron Wega


Good day.
First, Have your tv 's circuitry be resoldered. this might be a case of loose contacts particularly along the crt circuitry. the longer you operate the unit at this condition, the faster you are counting the possibility of shortening the lifespan of your tube. 9 years is quite a young age for a unit which has an average of 18years.


response is highly appreciated.
