Turned on the tv, was showing d-17, i hit channel up, it went to d-18, so pretty much was showing d, i guess that means digital, not sure how it switched over to that , but then, after getting the channels to reappear, the picture is fuzzed over with a tint of green, cannot seem to get the picture back to normal, any suggestions? i hear about the ic and i'm aware of what it does, however, why would it suddenly malfunction, could it be something else, based upon what i previously stated with the channel swicthover to digital? thanks for any suggestions you may have!

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/
That could be one of two things first being the front keyboard and possibly a main board. However the keyboard is usually the cause of those two issues. You can get replacement boards with free tech support for diagnosis to determine which board you actually need at www.tvrepairworld.com just hit the contact us button and enter the model number and symptom
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.
There is a board that manages the power going into your tv I would check around with local mom and pop tv reapir shops. The board is not expensive its the labor I am not sure where you live but I am sure there are local techs that work on flat panel tv's. They are pretty affordable these days. Most flat panel tv's are rated for 60,000 hrs as there life span. Hope that helps
I suspect your tv has gone back to air and should be in cable mode; you will have to go into menu where channel programming takes place. Select cable and autoprogram; it should pick up the missing channels.
