Hello, My name is Dave, Are you willing or able to remove the back cover from the TV? If so do you know how to use a DMM (digital multimeter) or at least know some one that dose? My reason for all the questions is in order to figure out what PCB board is bad you need to at least test the fuses on all the main PCB boards (Y sus, Z sus and Main power supply). To do this you will need to have a DMM that can test for continuity. Please feel free to give me a call or message me if you have any questions or if you would like some additional help! Ask for Dave @ 1-503-432-9904 / email@example.com

this faint picture issue is usually caused by a bad z sustain board. it is the smaller scan board on the right side of the tv when viewed from the back. it has some large cables that energize the plasma panel, dont confuse with the y sustain which has the tiny ribbon cables that address each line of the picture.
there should be a # on the board indicating the part number, plug it into a search engine to find parts.
this could also be a low voltage or something else, check the Vs and Va voltages and confirm theyre correct with the ones listed on the sticker inside the tv. Be careful this is dangerous and you can get shocked if you not familliar. The heatsinks can be energized and shock you , exercise caution. if you order a z sus board, make sure you can return if it doesn't fix. I'd say 95% chance its a z sus

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.
