Changed plugs.
Turned power bar off and on
Other components are working
Tried unplugging cord from tv and plugging it in again.
Tried turning on using remote and tried turning it on manually, nothing.
Was working fine this morning
My Protron PLTV - 3250 just went out yesterday. By this I mean it turned on and went out in a few minutes. I left it off and today it completely died. I opened it up because I always think I can repair things. So what I found is a burn mark on the curcuit board of the power supply which is located inside the tv. On the other side of the burn mark is a (zener diode), this diode is burned out and therefore the power supply is not working. I am going to Radio Shack tomorrow Monday Aug. 31, 2009. The diode is very tiny but should be easy to replace with a sauder gun because this diode has place holders to hold the tiny diode in. If this does not work at the top of this page is a link that says power supplies for your tv for sale. I am going to check it out. Anyway just so you all who know about computers= the tv power supply is similar to the power supply on a computer. Just like a computer power supply comes in a case that you install into your computer and then you just connect the connectors to your motherboard and drives. Well in the tv the power supply is stand alone also, you can disconnect the wire connections in the tv and replace the power supply. If you notice the power cable to your tv is the same as a computer power cable, so the power supply in the tv is much the same as a computer power supply. I hope this helps you.

Aug 31, 2009- Hey the link TODDTHETVMD is posting has a picture of the Protron PLTV - 3250 power supply. It looks exactly like that in my tv. Buy it. All you have to do is remove screws and and cables and put them back and you are all good to go. It is as easy as replacing parts and components in your computer. Thanks TODDTHETVMD.

Hello, for the ones that took this power supply out and actually paid attention unlike myself, Was the one plug on the power supply connected to location CNS3 that is closest to the edge of the board or was it supposed to be plugged into CNS4 connector that is closest to the capacitors. I did not pay attention while disconnecting this plug and they are both the same connectors and the plug will fit in either but if you look on the solder side of the board the one connection has 2 posts soldered together and the other connector does not have these 2 posts soldered together. I used to have the blue light on the front that would blink green and then go out but now I have nothing because i may have plugged this connector into the wrong one and shorted something else out. Now I am in worse shape then i was in. Any help is greatly appreciated. Thanks
