I have a Vizio SV470XVT1A and after about five minutes of being turned on it
begins displaying red pixels and red lines on dark areas of what's being displayed on the screen. It does not matter what input is used, the red pixelation occurs whether you use hdmi, composite, or external antenna inputs.
Other than the red pixel problem the TV works, ie; sharp picture, sound works, inputs all work, etc.
I pulled the cover off the back and have checked all the connectors to make
sure they were properly seated. I also inspected for bad caps and fuses and
I am getting steady 24 and 5 voltages from power supply.
From the various internet forums I have read its either the LVDS cables, the motherboard, the daughter board, the t-con board, the power inverter boards, the LCD screen, etc. I'd like to narrow it down a bit.
Please keep in mind that I am not electronics technician, but a sophisticated wire wiggler and I do have a multimeter and I can do almost anything, as long as it's explained to me in English and not Technospeak.
Any help is appreciated.
