42" plasma that will turn on, (green light comes on), then it will click and turn off. It will continue doing this until I completely unplug the power cord. Is this a power supply issue?
Replace the power supply it is a simple fix if you can hear the relays click 2 times or more replace the power supply board you can order them from UNION Electronics ask for kyle when you call ,,if the power supply isnt the problem then it will be the control board located below the power supply board I have repaired a few of these the voltages are marked on the power sullpy board conections be careful there is a VERY HIGH AND DANGEROUS VOLTAGE FEEDING THE X AND Z BOARDS DONT REMOVE THIS WITH SET PLUGED IN IT IS HOT ENOUGH TO BURN A HOLE IN YOUR SKIN AND EVEN DO MORE DAMAGE TO YOU if your not sure what to do Call LG they have a good support theam there

Yes this is the problem with the SMPS section or with the power switch circuit. You take it to the appropriate service to get the things done and to avoid the major issues.
