Re: Hitachi 50UX57B 50 inch Rear Projection smearing...
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.

What exactly is the screen doing? Is it black? Is it smearing? Is it showing only some letters and then very smudged and very dark letters?
Since it is likely that the screen you are talking about is an LCD or LED device, it is a sandwich device that is made up of various layers of electrically conductive material. The letters are formed via impulses that come to the back of the device and which then light up certain points while leaving others dark. The result is the display.
If the display is smearing, then it is likely that the conductive gel is leaking a bit within its cell-like space or it is likely that the rear electrical contact pad has been damaged, perhaps by an overvoltage condition. In this case, there's not much that you can do, other than replace the device, if that is at all possible (some devices are integrated into the device itself and the only way to repair it is to replace the entire device -- plug-out-plug in).
If the device is black, then it indicates the it is gone and has to be replaced. The same is true only if some segments are showing while others are not.
I want you to do a simple visual check of something that will tell me what the problem may be.
Go to a channel that is in black and white--old movie and tell me what color the screen/picture is.
You can also turn the COLOR in the customer menu all the way off and look that way.
What we are trying to see here is if TRACKING is set correctly or has changed. If the screen is somewhat to medium reddish it may be an adjustment outside of the customer menu.
Let me know what you find--I have seen several of these where the black and white picture was somewhat red--the idea is it should be as close to black and white as possible--if red is the predominant background color the picture will look reddish.
If this has helped and you confirm the red instead of black and white picture--I can tell you a easy way to adjust this.

Pull the front speaker grille off and remove the access panel. In the customer menu turn the color off so you have a black and white picture. get a flashlight and adjust the screen controls for the red, green and blue tubes until you get a nice black and white picture. then turn the color back up.
Take the front speaker grille off; it is stiff but will pull off. Take off the access panel underneath; four or five screws. Inside you will find a screen/focus block control assembly. Get a flashlight. Turn up the screen controls SLIGHTLY. for RED, GREEN AND BLUE. The best way to do this is to turn off the color first and make sure you end up with a good black and white pix ( not tinged green, red or blue) then turn the color back up in the menu.
daveT29 - I had my brightness cranked, too. The picture went dark and off-color after moving the TV from one corner of the living room to another.
After waiting for the TV repairman for about 4 weeks, I "fixed" it myself. Take the front panel off (4 screws, then a black panel) and blow out all the dust. I was afraid to use a swiffer duster because of the static electricity, so i just used with my mouth blowing powers.
Ok what we need to do here is determine if the picture tube is still good or not??.. If you turn the tv to a station thats has a brighter scene and turn off the color what does the pic look like ??is it Black and white or a certain color overall on the screen??
