Re: My TV has little green dots all over the picture.
You have the problem called "diffusion" errors, or some call it non-erasing pixels, etc.. You may be able to adjust the voltages to fix the issue. The 2 main voltages are VS and VA. The value they should be is listed on the back of the plasma panel. If one is off, then it could be the cause. Some manufacturers recommend turning up or down vs or va by 10% to fix this type of issue. Unfortunately, it can also be caused by many board in the tv.. power supply (where vs and va are generated) plus also the y and z drive boards, buffer boards, etc. If they are across the whole screen, suspect the power board and Y board most likely. I can talk you through all the adjustments but you will need a dc voltmeter capable of handling 250v. Let me know your skill level and we can fix this together.

Please try reducing the contrast a little and increasing the brightness till the dark shots are clear. Please also check the back light setting. It should not be too low.This should make all the dark scenes clearly visible if it only a setting problem. In case the overall brightness has reduced, please consult a local TV Tech.
You have a set that was involved in a large class action lawsuit---the optical engines in this model had issues where they turned red or another color---little dots in picture is a classic optical light engine problem---last time I looked the part alone not counting labor was over 600 dollars.
I believe there may be another setting, it has to do with auto contrast which can make the TV seems to have high contrast ratio but sometime it does not work right, espically on the scene with dark sky with stars, someitme it will will reduce the brightness to make black real black and you can loger see the stars in the scene. I forget the name of this setting, it may be in the user manual. Do you see that in TV HD mode in other movies with a lot of dark scenes?
The same thing happened to me Twice!. First time it was under warranty. Now it it out and Vizio has not interest in helping me. The first time the repair man changed the motherboard, which worked for about a year. Looks like I will be buying a new TV soon, but certainly NOT a Vizio, they are junk Anyone out there know how much a motherboard costs?
edge enhancement option i think would be enabled if you are in dynamic or movie mode. What it does is to enhance the contrast of the edges of 2 different colors.
I have the LA32S8, similar specs but only 7000:1 CONTRAST ratio. when playing dvd, i set it to movie mode. Settings vary on different tv and player. you can adjust first the backlight, then brightness then contrast, color and sharpness. the brightness you adjust by choosing the level that shows enough details on dark scenes. adjust if its too dark not to see the details of the scene. contrast, you can set by distiguishing vivid colors of the picture, dont put too much contrast as your picture would look flat. it should have a 3d look, same also with sharpness, you can experiment on the face of a person to show details on the edges.
color you set just enough to make it accurate on color reproduction.
My settings for movie are
tint g48 r52
digital NR off
black adjust high
dynamic ocntrast high
edge enhancement on
color space auto
