Question about Toshiba 42HP83 42 in. HD-Ready Plasma Television
Red dots on the dark colored areas
Red and green dots on screen
Posted on Feb 22, 2009
Each pixel if u look at it closely has your three primary colours red, green and blue if u are only seeing red then chances are that those tiny bulbs that are filled with xenon gas have blown leaving u with dead pixels i have worked closely with the manufacturers of plasma and lcd tvs, they will give u time frames like in the first year if it blows 10 or more pixels it may be fixed or replaced under warranty... after a certain amount of time they will not repair as they class this as a consumable product to a certain extent and therefore in the fine print they dont have to completely honour such warranty... like a bulb in a projector they will not cover that under warranty.... they only have 3000-4000 hours and the plasmas average around 10 000 - 15 000 hours... hope this was helpful

Red dots means dead pixels if you can return it or sell it because it can sometimes spread out, but you can get it fixed for about 140 dollars at minium at a place that fixes the panels and that of tv's if you can tho return it ASAP

This is know as diffusion. You will need to locate the Vs adjustment inside the TV and vary it up and down by NO MORE THAN 10 volts. If this does not correct the problem then you will need to replace the Plasma panel.
