Rather hard to properly diagnose this one off such a short description, but...

1/ Bulb OK, not over hours or otherwise damaged?
2/ Is it constant for all images, just a general coloured haze, not a strange "shadow", "ghost" or "fringe" that alters depending on what you display?
3/ Lens nice and clean?
4/ Surface you're projecting it onto also clean and at least nominally white?
5/ Input cables all fine at both ends and work correctly with other output devices (TV and/or computer monitor)?
6/ Haze still in place with different cables and input devices?
7/ Does the projector regularly show the same static image for extended periods?

The VT460s were buggers for suffering from internal LCD and filter glass issues if allowed to overheat, and with image burn-in, especially if fitted with unusual lenses (e.g. extreme short-throw); I've had to do internal cut-and-swap surgery on a few of them before, with donor image elements from projectors that died due to other problems. I can't say the one VT470 has shown any sign of similar, but the two VT480s are worse if anything. So it's entirely possible that we just got the one good VT470 out of the whole production run. As intimated by the above, it could be anything out of a failing bulb, dirty lens (or internal image element) glass, image burn-in, LCD/filter damage from overheating (and mind that being turned on showing a "blank" screen for ages can cause a similar effect, as all of the bulb's 200 watts of light energy is then being completely absorbed by three thumbnail-sized pieces of liquid crystal... the bulb doesn't turn off unless the projector is shut down completely!), problems with internal circuitry, dodgy cables, unsuitable projection surfaces, or problems with the devices feeding images to it. It really is a minefield until it can be narrowed down.

Black and white specks from InFocus X1 projector

if you can get a menu when you press the menu button, reset the settings to factory default. if you don't get a menu, the color wheel or the dmd chip is bad. either way, you'll have to replace the entire optical engine. and unfortunately, infocus no longer has any more in stock.

Sony VPL-CS5 menu will not display

Give input signal to the projector and see that if the menu appears or not on the screen.
if menu comes on the screen then put the backgroung color to blue, instaed of black.

if nothing comes on the screen, then the LCD panels are faulty.

Hi Guys,

I recently struck this issue with one of our PB6100's. To resolve I did the following:
  2. Under the Fan menu select "More Options". You should then be in the "Fac7 Submenu".
  3. Select "Hard Reset". Note that this will reset the lamp hours also!
  4. Power off & then on again. Test input.

The above worked for me. Hope it helps.

My projector can't handle white

Hi there

The next time you send your Projector for a service ask the technician to check the run rates on your colours as well.

It can unfortunatelly only be done properly in the Service Menu of the unit.
