Hello
The oscillator section of the power supply is not working. It will be very difficult repair these kind of power supply boards. Replacement as card basis only could be done.

SOURCE: No power to my Protron PLTV 3250. What can I do

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.

My TV will not pwer on, I have replaced the ac power cord and made sure the switch was in the on position that is next to where the power cable gets plugged into the tv. The blue led lite in the front is...


This is common problem with the PLTV-3250, the power supply DC filter caps go bad, 5vdc standby transistor and diode shorted out.
Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out Q7 and ZD4.

Check the fuse, if it is blown, replace with exact same one. Try again, if it blows again, its a power supply problem for a repair shop.

You need a new power supply. You can get one from Power-On.com for about $64.00 including shipping and handling. I had the same problem and had to replace my power supply.

Connecting a Protron PLTV 3250 to a home theater system


Standard RCA cables are fine to connect both units. If home theater and tv has Component Video (Green-Red-Blue) connections, you can get better video result.
