Are you sure theres no sound, or is there a possibility the unit may be in AV?... Most likely cause is the Y-Sustain board blowing.

Loud pop


If there was a loud pop then it would appaer a fuse has probably blown either on power supply especially if there is no indicator light showing. If you are getting the red stand by light then possibly a different fuse on the sustain board has blown. You would need to remove the rear cover & check any of the fuses. Most likely if they have blown something more serious has occured to cause & replacing the fuse will result in it blowing straight away.

No pic or sound


Hi,
If you have confirmed that your power cable is connected properly from your TV to the wall outlet (bypass surge protector strip if you are using one), then no picture and no sound is typical of SMPS (Power Supply) board gone bad. It can cost upwards of $200 plus labor. The good thing is, LG generally offers two (2) years parts and labor warranty for their big screen TVs. LG Repair turn around time is usually fast. Goodluck!

Power; No Pic or Sound


Hi, If you had not moved it, I may rule the SMPS (power supply board) went bad.
The unit may have suffered excessive shock that it knocked loose a connecting cable or two inside the unit. Don't be a hero though by attempting to pry the unit open. LG generally has a two (2) year warranty and they're super on repair turn around time. Call it in and they'll fix it pronto.

Best Regards
