My t.v. was working fine yesterday. However, today, text is double vision, super bright contrast with red, green and blue color

Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

Brightness-50% Contrast-50% Blue, Green, Red- All 100%
These are defaults on all monitors.

yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!

I would say the crt's are at the end of their life.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

This is a convergence problem and is either bad connections at the convergence ICs or defective ICs. If you can solder, you can repair this yourself. Let me know if you wish to repair this and I can provide you with additional details.

Call Vizio tech support and start a case. i am having the same issues with mine and i have sent it back. they will be replacing it this time.

My Dad had a Hitachi rear projection with same problem blue and red were fine green was out of allignment and could not fix. Problem was the acual projector inside TV the cost for repair was more than TV was worth went out bought plasma.

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
