Question about Sony FD Trinitron WEGA KV-27FS100 27" TV

1 Answer

Screen Doesn't turn on, light blinks four times

I have a Trinitron WEGA model # KV-27FS120, chassis style B06. At least, I think its a B06, the numbers have mostly flaked off. It was manufactured in Nov. 2005. When I plug it in and press the power button, it clicks, blinks four times, pauses, then blinks four times again. It continues this pattern until I unplug it. If someone could just point me to the right fuses, or whatever it is that is screwing up, I would really appreciate it. Also, I don't know too much other than how to solder and what a resistor looks like.

Thanks
Erik

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.

Blinks


The blinking standby light should be in a repeating pattern of a fixed count of blinks. Please post that count here as that will indicate the circuit in which a problem was detected. Armed with that info, we can then tell you the problem and probable solution.

KV-27FS120 blinks 2 times continuously...


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...
