hi,
Error code 2-2 indicates "Short Protect Circuit" problem in tv.
Need to check pico fuses in power supply as one or two got blown due to bad convergence chips.
Below is an exploded view of tv chassis, power supply and convergence area has been marked to give you better idea to look for pico fuses.
Unplug tv from wall socket before to repair/check any thing inside tv.
Hope these info will help you.
Let me know if you have additional question.

Look through the ventilation slits at the back of the TV with the room lights out. If you do not see white light light bleeding through the back, you have a back light failure. It could be the inverter circuit which lights up the CCFL ( cold cathode fluorescent lamp ). You will need professional help to replace it and could cost you about 70 to 100 $ to fix.
