SOURCE: My lv-x2 cannot run with the red colour -

It was not a problem of the beamer, but my notebook has a loose VGA-plug. I fixed it by slipping a handkerchief below the plug. Thus I could carefully lift the plug in order to reconnect the cable. The colours are just fine now!

There is no yellow colour in my emp 7600, can you help me how to solve this problem

Yellow light is made up of red and green light.
Your projector has 3 LCD panels. You need green and red to make yellow.
go into the menu and check that all the colour values are reset back to standard.

I have a Canon LV-S3 Projector that has a blue discoloration that seems to grow after a period of being on, when left off for a while (30 minutes) it will shrink back down to a small 2" x 4" (W x...

What you describe is caused by heat from the lamp. That in turn is caused by either a very old lamp, (as the lamps age, less light comes out and more heat is generated), blocked filters, dirty fan blades/fan not cooling properly or contamination of the LCD units.
It is not recoverable and will, unless the fault is found, get worse up to a point of total lack of one colour. Usually the blue is the one that suffers most due to the UV light from the lamp turning into heat.

Picture colour is wrong. Too much green and pink.

first reset the settings to factory default. then swap out the cable. if you still have trouble, replace the colorwheel.

New Bulb (30 hrs). Screen flickers after 10 minutes, color changes with green tint, then bulb shuts off.

Hi, I had a similar problem - the screen flicked through blue, green and red sometimes with a slight ticking noise. The problem seems to be that the colour-wheel is getting stuck - the first time this happened I sent it back to optoma who gave it a clean - it has happened again since thouegh and I just took the case off (you'll be able to see the colour wheel under a black plastic flap - remove the flap) I then used a cotton bud (q-tip) and turned the colour wheel whilst lightly pressing the cotton bud against the wheel - I also gave everything a blast with a can of air. My HD72i is ceiling mounted - optoma suggested putting the hoover pipe across the vents every now and then to keep the dust down. Essentially it's dust that is stopping the movement of the colour wheel.

Hope this helps.

My lv-x2 cannot run with the red colour - it´s dead! How can I get the red colour back?

It was not a problem of the beamer, but my notebook has a loose VGA-plug. I fixed it by slipping a handkerchief below the plug. Thus I could carefully lift the plug in order to reconnect the cable. The colours are just fine now!

When trying to watch a film off the computer through the projector the colour red comes out green on the projector.

check your cable and use a different laptop or desktop to eliminate the projector. always do a factory reset.

Acer projector

A DMD has no inherent colour capability - it's just a configurable mirror array. If you want to do full-colour projection, then, you'd expect that you'd have to use three DMDs and three coloured filters - red, green and blue.
But if a single DMD's switched in synchrony with a rotating "colour wheel" - a spinning tri-colour filter that lets through red, green and blue light in turn - then the very rapid switching speed of the DMD lets it lay down red, green and blue images in such fast succession that the result is a perfect colour image.
You can do the same trick with a single LCD panel, but it's not a good idea; LCDs are transmissive, rather than reflective, devices, and block something like half of the light that tries to get through them. To maximise brightness in LCD projectors, a three-panel design works better. If you try to pump the entire output of a super-bright lamp through one LCD, keeping it cool becomes rather challenging.
The extreme smallness of the moving parts on a DMD mean that it behaves like a solid state device, not a mechanical one. For all their complexity, DMDs have very high Mean Time Between Failures (MTBF), and well-made projectors based on DMDs can be expected to last easily as long as LCD units, and probably longer. If a DLP projector fails, it's not at all likely to be because there's something wrong with the DMD.

Optoma h27 colour issues

Check to be sure that the projector is in the correct mode. If it is expecting an RGB signal and you send it (Y,Pr,Pb), you will see the picture as you describe. The same works for the above reversed. In all likelyhood, you are sending RGB and the projector is expecting the other.
