First, understand the dangers of high voltage and charged capacitors inside a TV set! Discharge all capacitors and the picture tube in a safe way before proceeding.

What kind of IC is it?
If SurfaceMounteD:
1. Heat the IC pins and use a solder wick to remove ALL solder tin.
2. Use a sharp screwdriver or a knife to gently lift the IC from the PCB. Pay close attention if any of the pins is still attached to the PCB, if so, repeat step 1. Be careful, if you break the PCB, the Sony is ready for the dumpster...
3. Put the new IC in place, begin to solder pin 1, and then the pin most far away from pin 1.
4. Solder the rest of the pins, as quick as possible to not overheat the IC. Don't care if solder short circuit the pins.
5. Use a solder wick to remove all eventual short circuits that was the result of 4.
6. Inspect one more time to be 100% sure no short circuits remain.
7. finished.

If mounted through holes:
Same as above, with following additions:
1. a possible addition of a solder sucker.
4. The speed is still important, but since the pins are not so close, you should be able to do it without shorting.

Have a 4 blink error on a Sony KV36FS120

Yes, there's a posibility that IC561 is partially faulty but on the symptoms you've described, I would advice you to replaced first C539(470uf/25V) and C561 (47uf). I've suspected that these filter electrolytic capacitor is already leaky or dried up...

There are 3 reasons for 4 blinls

0 volts on pin 9 of the flyback

Base on the service manual information, yes IC561 could be defective.
You did not get the +15 volts because the TV failed to power up and the majority of voltages are coming from the flyback transformer.

Sony KV-32FS120 blinks 4 times

good day.
Have you tried first resoldering the terminals in the circuitry?
Also, try to check for the ABL supply near the flyback. Watch out for the small voltage zener diodes.

response is highly appreciated.
