STANDARD ANSWER FOR THIS PROBLEM:
MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:
UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.
PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.
Watch for power light to blink in a sequence:
1 blink-then 2 blinks-------no error
2 blink-then 1 blink-------X-ray protection
2 blink-then 2 blink-------SHORT PROTECTION*******
2 blink-then 3 blink---------deflection circuit problem
2 blink-then 4 blink---------vertical circuit problem
******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.
SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.
IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM
let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.
BEFORE YOU RATE THIS INFORMATION LET ME KNOW WHAT YOU FIND, i AM HERE TOP HELP.

2 blinks followed by 2 blinks is what happened. You mentioned that indicates a problem with SHORT PROTECTION. What now? What is the cost to repair?
It means one of the two pico fuses on center board is bad; if it is a ws55511 it means the single convergence chip is also bad; parts cost if you can do the repair under 25 dollars----I also have available for free, start to finish and step by step instructions which tell you everything you need and how to do the repair.
I can also tell you best place to purchase parts; Let me know if you want the instructions (email?) and I will get them to you----you can look them over and decide if you or someone you know can do the repair.
98% chance the STK-393-110 chip used in the model indicated is bad.
I have also photos of the chip, the fuses etc.
