Question about Sony FD Trinitron WEGA KV-27FS120 27" TV

1 Answer

KV-27FS120 blinks 2 times continuously...

I have a Trinitron WEGA model # KV-27FS120, Chasis BA6. It was manufactured in July 2005. When I plug it in and press the power button, it clicks, the stand by/timer LED blinks four times, pauses, then blinks 2 times. It continues this 2 blink pattern until I unplug it.

1. Is this an easy fix for a DIY'er?
2. Can I order the part through Sears?
3. Is there a diagram of what the part looks like and where it is located?
4. Is the tv worth fixing?

Thank you for your assistance.
Mike

This is not for a DIY're.

It is possible that the flyback transformer and the horizontal output transistor have failed. Also there may be damage in the power supply when these components fail.

When troubleshooting, it is important that the tech locate the cause of the fault and also change the related components.

After the parts are changed, the power supply and the high voltage setups must be done to make sure that the voltages are in specs.

This type of work must be done by an experienced TV tech. He will have the necessary test equipment, tools, service manuals, and training. There are some very serious safety issues when working in a TV set.

Light blinks four times, screen doesn't turn on


PER TO WHAT SONY HAS TO SAY IT IS A VERTICAL PROBLEM. SOME TIMES TH EIC JUST NEEDS TO BE SOLDERED. IT IS ON A SMALL HEAT SINK IC545. IF IT IS NOT SOLDERED GOOD THE YOU PROBABLY NEED TO REPLACE IT.
There are three defects can cause the Standby/Timer LED to flash in groups of four:
1) +13V and/or –13V from FBT/pins 9 and 7 respectively are missing on Vertical Drive IC545.
2) Vertical Drive IC545 is defective (no reference pulses output on IC545/pin 3 to IC001/pin 78).DON...

Screen Doesn't turn on, light blinks four times


Good day.
First, A resistor looks like a little tube with different colors placed in stripe form and has two ends or terminals. The colors represent the value the 1st and 2nd 3rd being the significant digits. The 3rd is the multiplier and the 4th is the tolerance.

Consider the vertical IC of your unit being the cause of this. Also, there are cases wherein the X-ray protector resistor is to be blamed.
