Question about Televison & Video
Our plasma started "flickering". I will try to describe it. The picture is faded and blurry in the background of blinking or flickering. If I disconnect the cable box or change the input, the problem is still there. When there is no source and the tv is just on the blinking is there and the picture is a bunch of red, blue green dots, probably each pixel. I have the TV back off and ready. Any help would be much appreciated. Vizio tech support said I need a new "main" board. I do not probe much after that. Would you agree? If agreed, which baord is it? Is there a reputable place to get the part?
SOURCE: red pixels
This prob shows up often in this set. To solve , remove the 4,784 screws from the rear cover. Plug in and connect the set. Operate until red dots appear. Locate the V_SET-UP control on the Y-SUS board ( the one on the right from the rear ) . VERY CAREFULLY and SLOWLY adjust till dots dissapear and STOP. This adjustment is VERY sesitive and requires only the slightest adjustment with a small insulated screwdiver and a steady hand. BE WARNED ... there are high voltages and high peak pulses on these boards. Not all heat sinks are grounded... some are quite lively. Dont touch anything else, unplug the set and carefully replace the cover. Good Luck..

Try unplugging the TV for a few minutes (discharges the ballast/ps) then plug in and attempt to power on. I have the 42P Vizio over two years old and ran into the same problem a few times. First thought was a power supply issue, but the unplugging trick worked. Good luck.

Very common problem on these sets caused by bad surface mount caps. Check on ebay for a repair kit it's the only place I know where one exists.
