It may have detected shorted circuits or just have bad power supply due to bad DC filter caps with domed tops. You need to open it up and troubleshoot it, so far I did not find free service manual download for it yet.
Please read my guide to understand what to look for inside the TV.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Will Not Turn On


First you need to do a self test diagnosis and then if it comes up with:
SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB
Do self test by pressing Input/Device and Menu at the same time for 5 sec. the set will show a 2 digit seq. first blinks followed by a short pause then the second.
