Unplug it for about an hour to see if it will reset itself first. This TV is known to have power supply problem, but yours has 5vdc standby working because the red light on the front is on, and the screen is also lited up blue. The problem can be the processor in the main board and will need more troubleshooting if that is the case.

PLTV3250 have a blue screen and wouldn't power on. power button wouldn't respond to touch.


Can you please clarify the BLUE screen, but since the TV will not turn on, how do you get blue screen?
This model is known to have bad power supply module.
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 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.
