Sometimes when I turn on the Comcast HD Cable & TV the sound doesn't come on and I have to turn it off and on a couple times. I think it's the tv since I turn it off using the button on the tv. I wrote to LG but the instructions for the sound test aren't on my TV. I can't find a Sound Test on my model. They said:
Press Home/Setting on the Remote - I have a Setting button
Then Go to the icon that is represented by a question mark (Support) - I don't have any of this.
Can I do a software or firmware update on this model?
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
