5 times blinks shows incorrect white balance (AKB) error. TV needs Screen Volts (G2) adjustment.
Take off lower front panel, find Focus Block that has 6 control knobs, adjust Screen volts of each CRT (red-green-blue) and problem will be solved.
Be Careful while working in TV.
Let me know if you have further question.

I would suggest not to desolder that transformer until you are certain that is defective.
Try to change D6116 and D6301 first.
You can try Radio Shack or check this site.
Good Luck.

Google first the model number to find the full service manual with error codes and schematics and parts lists--I have seen it out there--problem suggests a power supply issue and that board (far left as seen from rear?) has voltages marked right on the board for most of the major plugs----you should be able to remove the board with power cord attached and do static voltage and resistance checks that way.
