DLP Colors Are Off - Picture Is Mostly Blue and Yellow

My DLP is about 5 years old. In recent weeks the color has been gradually changing from what would be considered normal, to a picture with a more blue and yellow hue. It appeared to get worse over time and now the picture is very blue and yellow. Recently, I've replaced the lamp and the color wheel. Neither had any impact on the picture.

What could cause the color to shift over time that's not related to the color wheel?

Thanks in advance for any advice.

Sounds like you've lost your red video signal (chroma) somewhere along the line. This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. The analog has all your inputs on it, except DVI and RGB which go straight into the digital board. The digital scales (upconverts) the signal to HD (1080 or native) and sends it to the DMD or light engine. See which inputs are distorted. If only DVI is clean then you problem is the analog board. If you menu and everything is distorted then suspect the DMD board. If you run component or DVI through the resolutions (480i, 480p, 720p, 1080i) you can get an idea between the digital board and dmd. The menu is generated on the digital board. Somewhere red is getting lost.

Samsung DLP Facial Colors off after changing color wheel


Do you mean that red and blue are reversed? If so, you may need to remove a jumper, see end of linked article. Pinkish-yellow or orange sounds like a good description of skin tone, but perhaps too intense. If the color is too intense, can you just lower the color level with the color control? Or can you just change the tint with the tint control? Otherwise, see http://www.jangro.com/electronics/samsung-dlp-replace-color-wheel/ including the comments at the end.

DLP Colors Are Off - Picture Is Mostly Blue and Yellow


You are missing either red drive signal to CRT or you have a cold / fractured solder joint on the television. Also with the set unplugged check with a non metalic object like a ruler or a wooden spoon and start tapping around in the front or back of set and see what happens. See if you can narrow which area of the set has a problem... Good luck future technician.. Happy holidays.. Jay

Picture fine for 10min.-then flickers(clicking sound)& then colors gone yellow


Looks like it's a color wheel problem-found a cleaning walkthru online, but it doesn't get rid of the loud hum form the CW motor. Also, it is thermal related-when the colors went out I placed a fan next to the color wheel and everything went back to normal. Several design flaws here and for $3000 these companies should do better-severe problems after a couple years is not acceptable.

Your problem most likely is on the signal board is my guess. If your not a technician it would be in your best interest to have him check L2C60 on the signal board.
