How to Fix Red Dots on Samsung Plasma TV

I got my Samsung 50″ plasma HD TV a few months ago and I started to see red dots all over the screen. I looked around and found several remedies for this including one where you take apart the back of the television and turn down a knob inside the television. But before you start taking apart your TV, check to see if you model requires a firmware update from Samsung.
Don’t worry, this isn’t difficult.
Firmware is a piece of program that your TV uses to internally control all of the little devices inside your TV.

First, take a look at the back of your TV to find out your TV’s model and serial number.

My Samsung TV’s model number is PN50C450B1DXZA. I had to remove the serial number from the photo above for security sake.

Next, go to Samsung’s support website at http://support-us.samsung.com/cyber/notice/pdp/pdp_reddiffusion.jsp and select your model number and enter serial number to check.

Follow the instructions on downloading the firmware. You’ll need a USB memory drive to download the firmware because you’ll take this memory drive and stick it into your TV.

I did this and now no more dots!
