It is very easy to replace the power supply.
- Remove the stand
- Remove the speaker
- Remove the back cover.
- Remove 4 wires connector on the psu.
- Remove the 6 screws on the power supply and replace it with a new one.
Hope it will help.

Im having similar problem and with my limited knowledge of lcd tvs and the voltages ALL being good except the pwr on or sw on voltage from the main board to the power supply which tells it to switch everything on Im guessing that something is going wrong on the main board. In the condition where it freezes it (the power on V) which switches everything on i get varied voltages such as 2.5 or 3 or (the normal 5v) and then when nothing powers up (blank screen) i read 0v on pwr on voltage but all my other voltages are corect (24v to inverter, 12 v to main board, 5v, etc.) Im guessing from researching this is that there is in improper voltage somewhere in the main board circuit. I have been unable to find it so i may order another board and post back.

it had no cord because it was no good
it probably could be fixed but the cost would exceed a new one which is probably what the original owners did
