Hi all i have a LG 42" plasma, i tried to update the firmware i think and i put 03.15.00 on my memory card stuck it in the tv and clicked update, it got to 100% and then the tv turned off and turned back on as if it was rebooting but when it turned back on it has no picture just grey, and also i cant control the tv with the remote control or the buttons on the tv! Iv tried pulling the plug out etc and nothings happening! Can someone help? Maybe tell me how to reset it? Or downgrade the firmware or something just to get the tv back on, thanks in advance! Kriss.
