Sounds like your bottom buffer board is on its way out .
Will also need to check the y sus board as this some times causes the buffers boards to fail.

Dots on screen


The snowy dots and dots are typically from a poor signal going into the TV.

If there are colored pixels that stay lit all the time (like a red pixel and never goes away) and for any input, that’s called a stuck pixel.

A stuck pixel may be caused by a bad Y-Sustain, Y-drives, Z-sustain, and or a bad plasma panel.

Good Luck.

I have a LG Plasma Flat screen TV. I purchased it


With seeing the picture it will be hard fro me to tell what..I am going to guess according to the information you've provided.
It could a buffer or a signal board(s). This TV is only 4 Months old I would call LG and file a warranty claim. LG (800) 243-0000

Best of luck
