Pixel misfiring (diffusion errors) are caused when the tv is not firing and erasing the pixels correctly. It can be caused by a number of things, usually a voltage or waveform is off somewhere. If you just bought the tv, return it and get another. If you are out of warrany, you can remove the back panel and run the tv to check the voltages. Don't touch the heatsinks! they're electrically hot and will zap you.. the voltages are labeled on the back of the plasma panel with a sticker. first check Vs and Va. sometimes you can check -Vy, Vset, Vscan and others if labeled on the board. If you have to adjust waveforms you need a very $$ o-scope and should get qualified technician to adjust. If a board is bad, its likely your power supply or Y-sustain pcb, and less likely your Z-sustain or contol (logic) board.

You are connecting it into the wrong input. The Wii comes with a RCA cables that should go into the Video (composite) input that has yellow, red, and white. The component input will not work with the RCA cable input. Plug your Wii into Video1 and you should get the right colors. There should be another HDMI on the side of your TV, there are inputs located both on the back and side of the TV for your convience.

Wrong connection. Hook up the component output from DVD player or Wii to TV component input using component cable(red, green and blue plug)
