i had the same problem with a 32 inch and i kept "clicking" the channel changer on the remote to force the tv to go to another channel (that had previously been selected during the initial auto scan) --- still trying to figure out why the tv locks onto the scanning for channel

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.

Had the same issue, I replaced two 1200uf caps on the power supply board and now it works fine again. Remember to replace the caps with caps rated for at least 35wvdc.

There are 4 bad Capacitors in this TV. LG just doesn't wnat to tell anybody......
I purchased four 2200uf @ 25v capacitor’s for $8 at a repair shop. I upgraded to 25v because these will run cooler. The tv came with four 2200uf @ 10v Samxon caps that seem to be problematic in all the units they were used in. Do not buy Samxon if you do this yourself.... I opened the set by taking off the plastic back panel and then by removing the second metal panel. There are three boards and a hard drive. The board on the far left just above where the plug goes in is the power supply board. There are five data cables and one red power cable attached to it that can be removed simply by unplugging them. The board is fastened to the unit with five small screws, one on each corner and one in the middle of the right side. Look for three green capacitors grouped together around the middle of the board and slightly off to the right, you will probably see one that is bulging out at the top. This is most likely "C235", the main problem. The other three caps that need replacing are C202, C201 and C219. C219 is closer to the top part of the board.....
The process to replace is simple, believe it or not, and it could save you hundreds of dollars. 1, Go to RadioShack and buy a cheap soldering iron and a small roll of solder. 2, Buy four, 2200uf @ 25v capacitors, online or at an electronics store. 3, Plug the soldering iron in and let it heat up. 4, Locate C235 on the back side of the board and mark the negative terminal with a felt tip marker (you want to make sure that you put the negative terminal on the capacitor through the right hole, otherwise you will pop the cap. The negative terminal is clearly marker on all the capacitors). 5, With needle nose pliers, grip the cap and pull down while heating up the terminals. The cap will eventually come out. 6, Put the new cap in (you may need to heat the solder that is left on the board to clear the hole so it can push through). 6, When both terminals are through, bend them slightly so it stays in place. Take the solder and stretch out a few inches off the roll and while holding it in one hand, lightly touch the base of the terminal where it comes through the board, with the soldering iron and the solder at the same time. --- Try not to use too much solder.. you only need a tiny drop. This will solder the cap in place. 7, cut off the terminals close to the board with some snips and repeat this on the other three. 8, put the board back in, plug in the cables. Test the TV before putting the back panels on. It should work fine if all went well..... If you hear a pop than you reversed the terminals on a capacitor and that one will need to be redone correctly.... This might sound lengthy and potentially difficult but its worth a try. Otherwise you can pay someone to replace the entire board for BIG BUCKS with the same junk caps on it and have the same problem in a year or so. LG doesn’t want to take responsibility for this and I'm sure that it has cost a lot of people a lot of money for about $8 in parts........... This worked for me and it can work for anybody with the same problem.. Good Luck!

Yes, he means 2200 microfarret (called uf from here on out). Another important concern when buying a replacement is the voltage. You need to get something that is at least 25v. I recommend a 35v or better. Another notable point is that this may not always fix the problem. As with mine, there was also a 1200uf (microfarret) 35v capacitor that was blown. You can tell this because they bulge at the top. I have both of these caps (2200uf 35v and 1200uf 35v) on order and they will be here tomorrow. If I do not post back here then they fixed the issue for me. I suspect that this will resolve the problem. Look for bulges on top of the caps. This is an indication that they are blown. Most all of you experiancing these symptoms will see the 2200uf cap bulging but you may also see others bulging too. If you do then you need to replace those too. No electrolitic capacitor should be bulging at the top so if its bulging its bad, and if its bad then your tv will definitely not work. Have fun.
