Vizio VO370M screen comes on but after a few seconds all the color fade and the screen looks white. Should replace the TCON board first or the main board?

SOURCE: vo370M no color on dvd color on tv godd but only

Please change the display settings on DVD, the settings is not NTSC only set PAL then color Display will apear

SOURCE: Intermittant white faded picture

Since it is intermittent it will likely be hard to find but here is some general information and ideas since I have worked on hundreds of the Mitsubishi sets.

If the issue was with just one of the 3 tubes the screen color (background) would change--so not that.

These sets are prone to Glycol issues (coolant leaking from the tubes) but since once that happens it does not take time or even come back that is not the issue.

This set has 3 hidden menus--
One: advanced Convergence adjustments that can be saved.
Two: Adjustment menu(keep out of that one!)
Three: Option Menu

That menu allows a hard reset of the entire set that sets all settings back to factory.

The convergence is not affected and it has been known to cure all sorts of odd issues like no sound, inputs not working, odd brightness and video issues, and others.

If you have labeled video inputs from 1 to DVD etc those will be removed, set will come on in air band on channel 3 so will if using cable have to switch back to it and auto program channels etc.

It essentially puts the set back to the condition setting wise that it was when new in the box.

The only reason I suspect this could help is if the set has developed some kind of processor glitch it will reset that also.

No harm can be done to try it---it requires the Mitsubishi remote and a four digit number code.

If interested I will give you a link to the full manual (free to download) and the page number with instructions for the OPTION menu entry and reset.

Change the input to some other device and see. Then if the problem persists, this might need attention by a qualified service technician.

This same thing just happened to me, don't mean to awaken a dead thread, but apparently VIZIO still hasn't fixed it. I found that the solution is to restart your computer or whatever device you're connecting via HDMI, unplug the HDMI component from the television and the device, wait for it to come back on, and then plug everything back in. Rinse and repeat if it doesn't work. Took me two tries to get it to work.

SOURCE: TV turns on fine, but after a few seconds, the screen fades to white, and the entire screen looks all whited out, can still see image, just looks like the contrast is turned way up.

T'Con board fault. Replace it. If you wish to get some details; visit the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
