If there aren't 8 pin IC's on the bottom side i ask you tell me the marking of IC6000 and IC101 (as far as i can see from a not well illuminated area)..

No Diif, that is not to touch, is the Flash eeprom for the standby software..

"2EC" is 256kbits so it's surely IC101..

Do you see the tv channels, as before? If yes the reset job is not done well or is not available for this eeprom...

If you want you can buy another eeprom, equal or not equal, is enough it is a 256kbit.. and change it so the tv will reset itself.. LG also often suffer from bad cpu or bad cpu soldering, so you can try reflow it even if probably it will work for too few hours...
