I had the 50px75u for more than a year and a half now. and for last 6 months or so ive been having this strange red pixel/noise issue with it. It comes and goes from completely non-existent to horrifying. Its happens on all inputs, HDMI, s-video, hd antenna.


I still have a couples months left on my amex warranty so i just wanted to get some expert advise and what be the cause. ive included the pic of said problem.


any help would be greatly appreciated, thanks

Take it back or get it replaced under warranty.

I have a Vizio with this issue too and it is caused by incorrect voltages coming from potentiometers on the video boards. I found the specs on mine and adjusted the voltages so that the red pixel storm only happens for 5 minutes when I first turn it on and then goes away.

the only real cure is to replace the Y sustainer and X video boards (at over $200 a pop if you do it yourself)...at least, that how it is for the Vizio.
