I have replaced a color wheel for a DLP Samsung TV but some colors does not appear making every face turned blue with less definition


Hello luis_crocchi,

Welcome, and thank you for using FixYa!

To answer your question: You have replaced the color wheel, but the light engine (jet) will probably need to be replaced also.
You will also have to have the color wheel and jet tuned (timed) back to factory specs by a TV Repairman as well. If timing and lighting are out of sync, the picture will be also.

Have a great day!

I am thinking about buying a Samsung 72" DLP (Hlt7288wx/xaa) for $500. The seller says a tv repairman says it needs a color wheel replacement. Do you think this is something that would be difficult to...


Yes,tvs with a colors wheels design into it are more prone to brake down and more quickly than tvs without colors wheels design into it.The colors wheel in the tv spins at 12000 RPM at every cycles to make and let the tv Light Engine shine a beam of light into a colors wheel to make and have a colors spectrums to make it to works for the tv.No projection tv with a colors wheel are not easily to be replaced have go through alot of trouble to replace a colors wheel itself.The tv colors sit way back of the tv have to take out many tv mechanical tv frames bulk heads even than can come to the tv colors wheel itself to replace it.Take ur $500 buck buy a "40 LCD tv less worry less head aches.

53 inch projection tv...seems like the color red and color blue have shifted giving me a picture with red and blue shadows


For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

There should be a jumper somewhere around the color wheel. I am having a problem with my color wheel, and after doing a lot of research I found that people that have the same problem as you changed the jumper setting. Try looking it up here on the net. Should solve your problem.

Samsung dlp color issue


I just had a service tech out and replaced the color wheel. now i have the same issue with the color...the people all look blue. He told me that now the the digital board is bad. It's the board were all of the connections go. I'm not convinced, as I remember reading something about color settings needing to be adjusted after color wheel replacement.
