Mitsubshi WD-73881 Color problems

Hey guys. My tv is starting to act wierd. It's starting to show some wierd shadows, It seems like all the white colors have a blue cloud over them. Anything black has like a rainbow of purple and green in them. This is really hard to explain whats going on with it. I notice it twice as much when the scene is dark on the tv.

It sounds like what your describing is what is called solorization.. whith this model mitsubishi recomends technicians reseat what is called the dvi cable and if that doent work they next recomend replacment of the optical engine. the dvi cable is inside the chais and is what feeds the signal from the main board to optical engine. a large computer type cable like a monitor cable ussally with two tighting thumb screws.

    same problem everyone has with mitsubishi dlp sets I found this is not always a light engine or color wheel problem but rather an airflow problem that comes about due to lack of air movement inside the chassis. to find out if that's the problem simply remove the lower back cover and aim a small personal sized fan 6-8" at the right or left side whichever is easiest but anglede so the air will get around the boards and exhaust out to the other side without issue. then see how long it takes before the color sync starts to lose control. If it is like mine, it will no longer happen, this is then solved by simply exhausting the hot air. I've given a detailed explanation in BAD CAPS FORUMS under mitsubishi dlp problem solved costs about $50 total but has a few hours of work involveed

Just replaced color wheel. When TV turned on seemed fine but then i noticed a grey/black shadow band on one side. What could be the cause?


I had a similar issue with mine from the factory. There was a grey/black shadow in the upper left. Called for repair. The guy took off the circular access panel on the left back side and there was a fingerprint on the projection lense. He cleaned it and it disappeared. Sounds the same. Maybe touched the lense replacing the color wheel?

Color Alignment


the most common problem when the tv felt is the shadows all over the screen (maybe the tv didnt show it imm but looks like now is there the problem)
second:there is a circuit in the tv that works when the tv turns on every day. prevents the tv showing shadows on the screen.
the answer is this: if that system that prevents shadowing is working then the CRT is broken and say bye to the TV. But if the expert tech can make sure the D' gauss system is not working and can repair it then you get tv back.

Green shadows all over the screen


You didn't say how old the set was and how much it's used, but the shadows you're describing sound like a bad green picture tube.

Hope that helps...

Check settings first to make sure no one changed anything out of the ordinary. Are the shadows that of a color or darkened shadow? It could be out of convergence, which can be corrected in the menu - or it could be low quality video cables to. Also, if there is no green, does a white color show up when you're in a menu mode (Red+Blue+Green = White Image)? If so, then the green picture tube is working and it's just a color adjustment, otherwise you may have to invest in a new green picture tube.

Screen losing color.. turning black and white


Your TV goes black & white, because your Wii could be NTSC or PAL which. If your Wii is PAL and your TV is NTSC then the TV will show a blac and white color. Since NTSC is for North America and PAL for Asia

Pictue is dark as hell


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.
