First make sure it does have at least red indicator on the front panel, if not, the standby +5vdc is not working, common problem with this monitor is dead power supply due to bad caps, shorted transistor and Zener Diode in the standby power supply.

Proton pltv- 3250 32 "lcd tv a friend gave me


To turn on the TV:

Turning the Display On and Off

There is a power switch on the bottom of the display and a power button on top. The power switch is used to cut off power completely, whereas the power button turns the screen off but
allows the remote to continue working.
To turn the display on:
1. If the power light on the front of the display is off, turn on the power switch on the bottom of the display.
2. Press the POWER button.

To turn the display off:
1. Press the POWER button.
2. If the display will be unused for an extended period of time, turn off the power switch on the bottom of the display and disconnect the power.

Please make sure you rate my answer 4 thumbs up! Thanks so much for understanding, it would be a huge help to me. I would be forever grateful if you could do this for me. If you still have a question or concern about this problem please just respond / reply to my answer here before rating my answer.

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.

My PLTV 3250 keeps switching from tv to dtv on its own!


I had the same problem and called the company. They suggested this solution and to my amazement... it worked! Turn off the TV manually (don't use the remote). Unplud the TV from power supply. Wait 1/2 hour. Then replug and turn it on manually. It should take care of it by resetting to factory settings. You will have to redo any color, hue, brightness, etc adjustments. Sherri
