My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the lance..it's something else..don't know what..do you?


Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html

I cant get the color right. its to red??? any help? i did notice with the back cover off, there are 6 adjustment screws


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 have to configure Colors with each power on. ***


The six controls you appear to be adjusting are the screen and focus controls for each of the three picture tubes. These usually only have to be adjusted as each picture tube ages or when replaced. You may either have a defective "focus block" i.e. the black box you have been adjusting, or the CRT's themselves may be going bad at this age. You will probably be money ahead to just replace the TV with a new HDTV set. At 13 years old, it shouldn't have much life left in it anyhow.

RCA 46" Rear Projection TV - Picture is Blurry and RED


That sounds like the screen and focus controls you are adjusting. It sounds like you have a bad HV Splitter inside the TV. #205064 or #204809 Depending on your model number. http://www.matelectronics.com/acatalog/Mat_Electronics_Replacement_Parts___TV_134.html sells them for about 20 bucks.
