Question about Mitsubishi WD-73732 73" Television

2 Answers

Mitsubishi WD-73732 has 1 inch blue/purple band at screen top.

I have a ~1.5 year old Mitsubishi WD-73732 and it just recently started having a 1 inch blue/purple band at the top of the screen. Perhaps it is a coincidence but I noticed it after I started using an Atlona VGA to HDMI scaler to extend's my laptop image on the TV. The band exists on all input sources (PS3, Cable Card and the Atlona scaler). I am still on the original bulb. The band is more blue on the left of the screen and more purple on the right.

    DLP.

    I have the same issue, it's more like a wedge, thin on the left, thicker on the right. It's not a priority to fix it unless it gets worse, but curious if anyone has fixed this issue.

    The solution to the original post of "Mitsubishi WD-73732 has 1 inch blue/purple band at screen top" was resolved (years back) by a technician who replaced all sorts of components (which was fortunately under warranty). Had it not been under warranty, I would have considered junking it - especially since the prices of new 73" DLPs have come done *so* much. I was a bit concerned about how much he took apart and replaced but it has been working fine ever since. I sure am glad I had that warranty (at that time).
    However... I like the set so much I bought the top of the line 60" Mitsubishi DLP on line for $900 total - but since the price was so low, I *did not* buy an extended warranty. Also in consideration was that I can easily move that 60" TV compared to the 73" one - if/when I have to simply junk it some day...

Is this a DLP or LCD projector?

    If its a fairly dark band, it may be a defect in the light tunnel in the optical path between the lamp, color wheel and the DLP imager.



    The light tunnel has mirrored surfaces which are typically glued into position. With the heat that is generated by the lamp, the adhesive may fail, allowing one or more mirrors to get in the light path.



    Its rare, but a defect in the lamp itself can cause a band of color. Take out the lamp when its cooled down, being careful not to touch the glass with your bare fingers, and look into the lamp. The back reflector should be shiny and without blemishes or breaks in the reflective material.



    And, its also possible to have a problem with the color wheel and the lens optics as well although I haven't encountered this myself.

    I have the same problem there is a light purpleish band along the top of the screen that gets wider going from left to right. I am currently replacing the bulb. I don't want to replace the light engine, thanks for any suggestions.

It will cost you probably in the area of $700.00 to replace the Light Engine. I don't think it would be a good idea to repair it. DLP sets have been out of production a few years now due to high failure rates of the light engines for all makes and models and the consumer cost for the lamp.

Error message: check connections or power-the connections for RGBHV or YPrPb may be invalid. The screen is a two tone blue and is flashing.


DO NOT do anything to your Mitsubishi WD-52525 until you read this forum overseen by a Mitsubishi certified repair technician: http://www.hometheatershack.com/forums/mitsubishi/11703-problem-mitsubishi-wd-52525-scrambled-picture-no-picture-2.html . There has been a worldwide problem in computers and TVs over the past several years with faulty electrolytic capacitors (from Taiwan) that decay, dry out, swell and die. The power supply is often the first component to go bad, but other systems also degrade over time. As the forum explains , this problem is widespread in these sets causing multiple types of display problems after several years of use. Mitsubishi is aware of the problem and will cover most of the cost of repairing the chassis, even years out of warranty, but apparently ONLY if you get an estimate from a Mitsubishi certified repair station and contact their customer support BEFORE doing any work on the set. I just followed the recommended procedure on that forum and Mitsubishi is covering half the cost of my $700+ repair when my 3+ year-old set recently died and showed only a blue screen. I'm not sure if this is your problem, but it might be.

Color fades out on tv


I have the same tv and the same problem (color banding, incorrect colors, colors blinking) occured after I replaced the lamp. I had a tv repairman take a look at my unit and he said the color index was incorrect, the tv doesn't know the correct colors to display. The best way to fix that problem is to replace the "light engine". The repairman replaced the "light engine" to my tv and everything is working great. My tv was still until warrenty so I don't know how much a new "light engine" would have cost.

It could be a bad lamp but I've run into many of these TVs with bad color wheel assemblies. Also, if you are getting a dialog box coming up with these words," airflow blocked, TV will shutdown ..." that's a defective thermal fuse.

This is a job for a mitsubishi authorized service center. A tech can disassemble the light engine and confirm that the wheel is the problem. If you're still in warranty, great. If you're only recently out of warranty, call mitsubishi for assistance. Remember that persistance pays off when dealing with large corporations. You very seldom get what you're looking for on the first call or from the first person you speak to.
