It is most probably the power supply board. There is a repair service for this board available at http://www.coppelltvrepair.com/p/791/lg-42lb1dr-ua-power-supply-board-repair-serivce-for-totally-dead-not-powering-on-or-shutting-down-tv

Most electrolytic capacitors have a marking on the side with an arrow pointing to the negative lead.

I purchased my set about 2 years ago. I experienced the same problems as other owners where the TV would not turn-on or will turn-on but become non-responsive or turn-off on its own after a few minutes. Some other owners have posted comments that the problem is faulty capacitors on the power supply board. I removed the power supply board and noticed that one of the capacitors had a bulge on the top of the cap. The capacitor is green and made by Samxon. The capacitor is rated as 2200uf 10volt. I made some research online regarding this specific capacitor. Apparently, this is a defective capacitor as other people have posted comments online on various other products that use this capacitor as also failing on their products. The power supply board has a total of 4 of these capacitors. I ended up removing all 4 which was really easy to do since they are not small and good size to handle. I was able to locate the a different brand of capacitors online for $2.50 and soldered them to the board. Since I had the TV taken apart, I also upgraded the hard drive with a 500gb Seagate DB35.3 which are hard drives made specifically for DVR's. The TV originally came with DB35.2 which was the previous model. After I was all done with the repair and upgrade, I turned on the TV and it has been working flawlessly. This confirms to me that the problem is caused by the faulty Samxon capacitors used on the power supply board. If you do not want to mess with soldering your board, there are retailers selling replacement boards for around $150-$180 however if you get a new board that has the same Samxon capacitors, I would assume that over time, the same problem will happen with the capacitors failing. As for the hard drive upgrade, the TV accepted the drive with no problem. I can now record 52 hours of HD and 127 hours of SD. Please let me know if you have any questions.
