Is it repairable, well, this question can be answered only after opening the back cover and evaluating the damage. From you side, please connect the TV to a different power outlet where other similar devices are working and see. Then try changing the input device to something that sure works. If it does not work even then, this may need attention by a qualified service technician.

The problem could come from the power supply at the first suspected one. If you have a knowledge of trouble shooting, open the cover then examine if any caps there look poping up. Use your finger touch on the top of caps you will feel it. If not, check all the fuses there then disconnect all the cables from power sup to other boards, except the main board. Check Va and Vs according to the label attached on the back of panel. If the power sup shut down, replace it with a new one. Hope it helps.

I had the same sympton on my tv...it worked fine one day and the next day it would flash a green light a few times you would see the screen power on, but still be dark then the power light would go red. I couldn't do anything on the tv no menus or sound. It turned out to be a bad power supply, a new power supply will run around $200-300 - in my opinion it wasn't worth fixing. My neighbor was able to fix my tv - he repairs electronics - ended up cost me $100.00 - its been running for 7 months now no problems so far...I can have him fix this for you if you are in the area - shipping makes this to expensive..he is located in south jersey...or you can try a tv repair shop ( i called for this but they wanted between $75-100 to just look at the unit + repair cost - i would of been back to the 200-300 range) let me know if you need help...John

Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...
