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

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.
