Question about LG 42LC2D 42 in. LCD HDTV
Most likely the problem is bad capacitors on the video module of unit.If you take the back off you should see basically 3 circuit boards-Power Supply,Main Board,T-Con Board.Inspect the main board and the power Supply Boards for bad capacitors,in most cases the bad ones will usually have a bulge on the top of the capacitor,a normal cap will have a flat top,if you find any of the caps have a slight or big bulge,as if they were getting ready to explode,they need to be replaced with the same microfarads and voltage rating which is printed on the side of each cap.Replace them one at a time,you will need a soldering gun ,solder and solder wick to properly do the job.You can find all the tools you need at your local radio shack.The solder wick is used to extract the old solder so you can put a new cap in,the caps will have 2 legs.Also you must look at the cap and line up the negative side of the cap to the negative symbol on the board,there should also be a plus symbol where the cap goes in on the board.Good Luck and let me know if you need more information.
