Mitsubishi RPTV has a blue shadow/image alignment problem


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You have one of two problems. Sometimes both.

Problem #1) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Converging problem


This is a rear projection TV that uses three color "guns" in a cathode ray tube . They are no longer converging at the screen. The convergence problem is usually a sign of something else gone wrong with the high voltage.
Do NOT attempt to open this set yourself. This type of TV can have LETHAL voltages inside for WEEKS after it is unplugged. The repair and convergence calibration will require a qualified service technician.

Picture on tv has blue and red going through the top and can people look like they had 2 heads on tv toshiba 42pw23p


try to align it by going into the convergence setting in your on screen menu, some proj tv have a multipoint conv alignment, this might do it for you, if it doe not then therre might be a problem with the red and blue convergence amps and on this model the digital conv module(dcm) can also be at fault.

Words are doubled red borders???


Just to clarify, it sounds like what you are saying is that the image appears to duplicate in either red or blue along the edges of the image (especially white lettering and probably increasing along the boarder of the TV). This is resolved by converging your TV. Convergence will drift normally on large screen projection TV's over time or through moving them. The Hitachi 57f500a has a feature called "Magic Focus" (pg 36 in your manual) which will auto converge the image. If the auto converge feature doesn't work, on page 37 in your manual, it explains how to converge manually. If you do not have the manual, I have the image of the pages below. If for some reason this doesn't work, please provide additional info and detailed prior to rating the help.

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.
