Agree on the faulty power supply caps. I also had a Korea made TV. Remove
the main board and examine cap solder joints for overheating or caps that
show discoloration. IIRC the caps are often physically close to
transformers.

LCD / plasma, check power supply caps. Failing that, if LCD, try
unplugging the backlight inverter. Many TVs will run happily with a
(faulty) inverter disconnected, but obviously, you won't actually see a
picture, unless you shine a strong light at the screen at an angle. You
will, however, normally still hear sound, which proves that the set is
staying on ok.
