Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

SOURCE: 37 inch LG LCD won't turn on due to power failure

Power failures can cause all types of problems, have you firstly checked the fuse in the mains plug? If that is ok then it may have blown an internal fuse in the power supply board, these are there to protect the rest of the circuit from power surges.

This is likely due to a failed power supply. Replacing the power supply board should solve the problem.

Unplug it for about an hour to let it reset itself and try again, if it still has problem then you will have to open it up or take it to the repair shop. The power supply module will have to be looked at first to make sure all the voltages are present. Right now the 5vdc standby power supply is working and may be partially function processor.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

BROKEN TV


Polaroid has a 1 year manufacturers in-home warranty on 32+ inch TV's. Contact them and they should send someone to fix the TV for you.

http://www.polaroid.com/company_info/ww.jsp?PRODUCT%3C%3Eprd_id=845524441765894%3FFOLDER%3C%3Efolder_id%3D2534374302029019&bmUID=1202320078795&bmLocale=en_US

Since it is still under warranty make it Polaroids "problem"

hope that helps!
