Re: mdl kp53v85 red is out of alignment and bowed
Your convergence ICs are bad. They are about 20 pin chips located on the D board. They are on the largest heatsinks on the board. Check the resistors and fuses underneath or next to the heatsinks with an ohm meter to make sure all are good as they can fail with the ICs. This is a difficult repair but can be handled by a moderately skilled electronics tech. After all bad parts are replaced, run the magic focus to hopefully re-align the colors. If you have to go into service mode to re-align convergence data, the complexity of the repair just went up another notch. On a sony, service mode is tricky and a service manual would be highly recommended. Your tv uses two stk392-150 ICs (ic 1502 and ic 1505)

5 blinks with this model number is :
replace q764 on blue Crt Pwb part number is 2sa1091. same transistor on the red and green just replace all 3 to make the job simple.
again the locations are q764/q706/q733

Convergence amp. IC's on power supply PCB need replacement.
Part # STK392-110 sub to upgrade STK394-160E. I use Hitachi ,
no re-calls! Not advisable to use generics......
Worth repairing unless you are ready for a change......T.
Part # STK392-040 X 2 Do not use generic-they won't hold up.
I use Panasonic brand with no recalls------wholesale cost about
30.00 each. Always replace both at same time = more efficient.
After replacement, alignment may be needed = let me know.
Lost of high voltage on the vertical amp was caused the bowing. That was a simple tweak. I'm sorry to tell you that the high voltage adjustments are rather precise and have major interaction with each other. The HV circuit is also used to power low voltage circuits to gain efficiency. If one or more are not within spec, the process to recovery will require bench alignment of the various stages. Seek professional help or consider replacing. Good luck
