stephanie, my hunch is that you have some bad capacitors. Do a search on youtube for capacitor replacement. It's not a hard job, but it does involve opening up your TV - and the inherent risks associated with that activity. How old is the TV?

Stephanie, check out this link right on iFixit! no sound and picture


Thanks for the replied Chuck.

Well my tv is almost 5 years old.

Ok , I will check the video on how to replace it,but I wonder how to get the part number to buy it? maybe I need to call LG.


stephanie, do a google search on "power supply board 55lx6500" and you'll get hits on ebay and amazon. It looks to be a bit over $100 for the board. I'd hate to see you buy this board and not have it solve the issue - check out YouTube for other LG models with similar issues to really narrow this down. Also, you need to be careful removing the back of the TV because there are areas with high voltage. ShopJimmy on Youtube would be a good contact for you.


i have the same problem replace the power and master boards it did not help.

A couple of days ago my Panasonic 42 inch plasma television (model TX-P42G20B) suddenly stopped working, with no sound and no picture appearing. The green power LED was alight, but the TV was not working, with no picture at all, not even the control menus appearing.

The repair engineer who came around fixed my TV within minutes, by holding down some button on the TV for some seconds to get into the engineer's Service Menu, and then reseting or changing something (I did not see exactly what he did).

He told me that TV engineers suspect that software updates sent from the BBC to the BBC iPlayer in the TV caused this problem. There is no proof of this, but this is apparently what some repair engineers suspect.

If this is the case, then this problem has probably happened to many people throughout the UK, and I would think that lot of people will just have gone out and bought a new TV, because it is often cheaper to do this than paying for a repair, if the repair turns out to be complex (but this repair was done in moments just via the engineer's menus, without needing to take the back off the TV).

Thus this presumed rogue BBC iPlayer software update containing a bug (assuming it was the cause of my TV going kaput) may have caused a lot of people to throw away perfectly good TVs, and to go out a buy a new TV, which is not necessary at all.
