Is this LCD brand new?
If is not brand new, there is a high failure rate with the power supplies. In about 95% of the time if the LCD is not powering up is because a defective power supply or back light inverter.
Let me know if you need further assistance.

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.

PLTV 3250 no power


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.

LG LCD TV Standby Light Flashing Red Continuously


I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.
