This is what is known as a dead pixel. If you have a standard wide screen lcd monitor it has over 1 million pixels. It is not super un-common for one to go bad. It will either always be dark or in your case always be lit. It is not worth it to repair, and in most cases unless you have multiple dead pixels with in a square inch of screen, it is not covered under warranty either.
Each pixel is individual and the problem will most likely not spread.

The white dots that come and go could be what is called ignition noise. Caused by something in your residence or on the power line to your living area. You will have to do some tracking. Take a portable radio and tune it to the 550mhz, you will hear a crackle or buzz, tune to the loudest that the buzz/crackle can be heard. Walk around to see were the noise gets to be the loudest. If it gets weaker you are moving away from the source. The source could be a dimmer switch for lighting, or a loose connection on a receptcle, or in the panel box that supplies the residence. Worst case it could be entering from outside source. I have tracked ignition noise as far as two houses away that had a bad butter control on a refrigerator that was on the same power line that supplied the neighbor hood. There are so many things this day and age that could be causing your dots. Yours come and go, so you will have to track it when it is acually seen on your tv. Sounds like something on a timer like refrigerator, Furnace, etc.

I have a similar issue from time to time. It is merely a bad connection from the cartridge to the system. Some dust or dirt particles are causing this. Give it a good cleaning and you should be good to go.
