Hi, I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs. Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture. If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it. Thanks.
Your having trouble with the vertical sync/deflection circuitry. Probably a driver since it clears up after it gets warm. Could be as simple as a cold solder joint but it's not something you can do yourself unless your a tv repairman.
