I need a new power supply for this TV, and I am not able to find one anywhere. It is UL listed, so it has to have an equivalent in the US, I just don't know where to get it.
Thank you for taking the time to answer,
Sear sells replacement power supplys for Protron televisions. Here is the website http://www3.sears.com/
Just search for PLTV32c and it will pull up a list of parts they sell. The power supply will cost you about 300 bucks.

Hi, This problem will occur under two circumstances 1, Faulty electrolytic capacitors in the power supply board 2. Faulty back light inverter board.
Fist of all check is there is any faulty capacitors in the power supply board. If you find or not try to replace all the electrolytic capacitors in the power supply board. In most cases this will solve the problem. I have added the some video which will help you
The second one is the inverter back light inverter board. There is no repair possible with the inverter board. You have to replace the board with a new one. As you didn't mentioned any model number of your tv its not possible to attach a picture of the exact inverter board. The back light inverter board will look like one in the picture
Many devices marketed as surge suppressors are actually 'temporary power taps'.
The rear of the surge protector unit should show the UL-rating of the device. If it's listed as a UL-TVSS, that's a surge suppressor. If it says 'Temporary power tap' then the only surge suppression may be a resettable circuit breaker, through which lightning could pass unchecked.
Most likely the TV power supply has failed, and the cost/complexity of the replacement all depends on the local repair shop. Modern LCD-TV power supplies are typically a $200 part, plus a similar cost for labor. If it simply blew an internal fuse, an honest shop would fix it for under $100, I would guess.
With respect to surge suppressors, the leader in this field is APC (amercian power conversion) and several other good brands are TrippLite and Panamax. These devices are not dirt cheap, but you get what you pay for.
The dust could cause the burning smell, if the smell has an electrical smell then most likely the capacitors are leaking in the power supply and about to blow/explode.
Is the power supply come from a desktop computer? If so all ATX switch mode power supplies have standard mounting holes and power connectors.
Take out the old switch mode power supply and take it with you to your friendly computer shop and compare it with a new one. Make sure the wattage rating of the new switch mode power supply is the same or greater than the old switch mode power supply.
