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

1 Answer

Light blinks four times, screen doesn't turn on

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, so I would appreciate a description of what the part looks like and where to find it in the TV.

Thanks
Erik

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...

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.

My sony trintron is stuck in stand by mode


If model number listed here (kv-27fs120) is correct the set if not coming on is in shutdown because either a problem in its power supply or something elsewhere pulling the supply voltages down and triggering shut down.

Someone would have to open and first check for voltages and or shorts--no real other easy way to troubleshoot this.

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.

Lines on t.v and stand by light is on.


Hard one to call as I have not seen the newer sony chassis yet BUT it sound like to me a fault in the PIP section if there is one or the crt driver circuit or even in the video jungle IC. It is only three months old so call the store where you got it as there should be a warrantee on the set.Good Luck
