Most likely the power supply board.

Lie the tv down on a bed and unscrew the back. Its only about 9 screws around the edge and look at the power board, on the left, see if theres any burn marks.

I have a brand new board I bought the other day for the same issue but before I replaced it, stupidly, I checked with LG and turns out mine is still under warranty so I'm stuck with a new board.

Let me know if you want it. I'll match any price you can find online.

Green light flashes but TV wont turn on


TV has detected an error either software wise or hardware wise. Has the tv sustained trauma lately? or a power surge? needs service.

LG 42LC7D-UB after few minutes the sound goes off and channel change by itself


When heats up, the supply voltage from the main power supply board goes less. Check all the soldering to this board for any loose solder terminals. Resolder all the suspected solder terminals by applying a little more solder. If it do not help you, replace the board as card basis.

Hard time turning on tv. I turn it on, green light flashes a few times then becomes solid green. No picture or sound. I turn it off and light becomes red. I do this at least 5 times before tv will come...


There are some capacitors on the main boardthat are low quality. You can buy a capacitor repair kit on Ebay that contains a set of capacitors to replace the offending ones - about 15-16 bucks. I soldered in the new capacitors and the TV has worked perfectly since.

My electric went off yesterday and when it went back on my tv wouldnt turn on it was working fine before the power cut we have changed the fuse but still nothing is there anyway i can reset it to make it...


you said you changed the fuse. (inside the tv)double check to see if its blown agian if not. keep it unplugged for about 20 minutes to reset the surge protector onboard . if you have done all that the fuse didnt protect your tv from the surge and it gone. IF ITS CONNECTED TO A SURGE PROTECTOR unplug it from that and plug directly into the wall TRY THAT FIRST let me know if this works.

LG 42LC7D TV does not want to chg channels after 5 min of use


There are some inductors that are out of spec. LG's original SB said to replace some of these with a jumper, but it only lasted a couple months.

You need to have the Total Main Assy replaced.

Tv turns off after 15 minutes of use


For bobby11 and luis, it is the power supply. Part Number EAY34797001 in the 42" and EAY34796801 in the 32". This is a known problem, and somebody should start a Class Action against LG over this one. Part is available online and easy to swap out for anyone with the most basic knowledge.
