You have a very good idea of what is happening,the power supply is likely being pull down by a shorted component,it could be a regulator or the output transistor.The power supply provides about 5 or 6 different voltages to be use for the different circuits,I gave you two ideas but it could be any of them.Be safe and take it in for service.

I have a broksonic sc-20145 and the dvd player drawer will not open/close. could it be a bad motor?

With your ear next to tv do you hear the sound of a motor trying to open the dvd door. If so probaly a plastic gear that has failed that opens the dvd door otherwise could be the motor. Just go buy a $30 dvd player and connect to the tv input. not worth repairing and stay away from tv/dvd combos in the future for this reason that your having to expierence now.

Experienced a power surge and TV will not turn on.

The TV's have a built in surge protector and must be repaired at a reptable shop.
