Hi guys

You will be looking at either repairing or replacing the Mainboard where all the colour processing is done.

The image color on projection is not the same as shown in laptop. There's is no red color.


It could be a broken connection in the computer lead for the red signal, or a fault on the projector that the red panel doesn't work any more.

To diagnose, bring up the projector's on screen display. If there's white in the menus then the problem is the cable. Replace it with a new one. If the menus are affected too then it's a projector problem. This requires the attention of a service engionner.

YELLOW TINT ON SCREEN MITSUBISHI TV MODEL WS 55313


The WS is a picture tube type rear projection first produced as a 2003 model year set.

A few questions and then a offer if needed.

Did this happen suddenly or after a power loss?

By reboot do you mean the recessed reset button on the front of the set?

I will presume if you turn color off completely the screen is some other color than black and white?

the offer: have you tried the Option menu this set has hidden, I can explain if needed.

I have a Christie LX100 Projector when projecting a white image there is some yellow tint. Is this something that can be fixed?


If the yellow tint is uniformly over the whole screen then try changing the video colour tint, hue, phase and other chroma related settings in the menu.

I have a Hitachi 57" projection TV Model 57F510.


You may well have either poor contact on the tube base of the colour that is missing or a poor contact in the tube itself. The latter is not repairable.

Colors bleeding, red tint around images


The liquid coolant between the guns and the lenses may be fogged, low, or both. If the red gun has fogged coolant, you'll see red fringing around objects. It can be drained and refilled with new coolant, but it's gotta be the right stuff. You may be able to get some from a junk set, as I have done with success. Shine a light into the front of each lens. If the liquid has gone bad, you'll be able to see it.

NEC LT35 color problem


If you're trying to project video, then the unit needs professional service. If you're trying to project from a computer, you may have a loose display cable, broken pins in one or both ends of the display cable, or broken conductors (wires) within the display cable. The computer sends its image information as a template of RED image components, GREEN image components and BLUE image components with the projector overlays to create the complete image with blended color values. (The computer also sends HORIZONTAL and VERTICAL synchronization signals, but those don'e affect the color content of the projected image.) That's why I'm suspicious of the display cable, conductors or pins.

Permanent Coloured tint


When the image turns pink, we find that replacing the cable between the projector and the lap top fixes the problem.
