A blue colour (light) comes out from everything on the screen

screen not coming coming standby only display led light

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.

I would try cleaning off the nozles on your print cartridges. If that doesn't help, replace them altogether.

i have the same dvd player the pink 1 i lent on a button and it went into black and white i have tried everything and can't seem to get it back into colour again, ive tried pressing all the buttons and nothing seems to work or come up with any black and white/ colour options :(

I can't imagine a setting that would cause this - It sound more like some sort of fault with the projector's blue LCD panel. (The image is created from a mix of red, green and blue light. If you loose the blue, everything will look yellow.)

Is it capable of showing any shades of blue?

Using any graphics or photo-editing software, create a solid blue image (R=0, G=0, B=255 in your colour settings) and if possible, display this full-screen. Is there any output from the projector at all when you do?

If not, it sounds like it need a professional repair.

Start by raising the screen control for the red and green to see if they have any type of luminance.

your colour guns (that's what they call the light tubes that produce the 3 main colours, red/green/blue) need to be fixed. One or two of your guns need to have the liquid that protects the lens flushed out. I had the same thing and the repair man came in took the unit apart and removed one of my light guns (blue one) and showed me the dis-coloured liquid. He drained the liquid and added new clear liquid which protects the heating of the gun and everything was perfect again.

Most likely cause would be a loose solder connection that expands as the set warms up until it no longer makes a connection. You may get the blue to come and go by hitting the side of the cabinet after the set is warmed up awhile. (don't hurt your hand doing this, and don't keep doing it to "fix" the set. The connection will have to be located and repaired). Otherwise, there could be a component going bad, including the blue picture tube.
