Now my power supply has gone have the projector in pieces, found a failed on transistor but because it's over heated can't read of it what type it was....

SOURCE: projector buttons locked

unfortunately, you need the remote. fortunately, you can use almost any sharp projector remote (same code). when you do get one, press (in this order)- menu, enter, enter, menu, undo, undo, menu.

White dots on the screen


Need more info. But initial suspicion is there is a problem with your projector.

Are they stationary and always in the same position? You may have bad pixels.

Are the dots there with no signal going to the projector?

What is connected the the projector? Detail the video path - try all the sources. The dots still there and in the same position on all sources?

It is probably your projector.

If some of your sources are fine - the problem might be from a connected source.

Hope this helps.

When I turn the projector on I get scattered bright white pixels showing up on the screen with no color. What causes this.


Hello!
Bad news: the problem is the light engine! most expensive part of the projector. Due to high temperature inside and extended usage with poor ventilation, plastic filters inside the light engine start melting and picture gets "spotty". Next, the color matrix quits and one of primary colors is missing. In any case, light engine is "goner". It's very big job to replace it. I would surrender to repair facility in your place. Or, if you can get replacement projector for a good price, just do that. Your projectors repair bill might be $500+,or more. due to high cost of light engine.
Good luck,
thanks,
Alex.

Hitachi CPS-220 is saying 'RGB is out of range' when connected to PC.


This would indicate that the display settings on the PC are outwith the acceptable range of the projector.
To solve this, right-click on a clear part of your PC desktop and select "Graphics Properties" (in Vista). You then need to adjust the display settings. That is a very old projector which will accept a maximum screen resolution of 1024 x768 pixels. Try changing that 1st. If it doesn't work, keep that screen resolution and also adjust the refresh rate in Hz until you get an image.
The native resolution of that projector is SVGA (800 x 600 pixels).

Screen adjustment


Adjust the screen area of the computer’s display settings to match the projector’s native resolution. Refer to your projector documentation for the optimum or native-resolution setting for your projector model. If you can't find this information or are uncertain, most projectors support a maximum of 800 x 600 pixels.
• With certain laptops, you might need to disable the laptop display to obtain the best image, especially when the native resolution of the laptop exceeds the native resolution of the projector.
• Font smoothing will automatically generate a cleaner font outline, both on your laptop and on the projector. To apply font smoothing, do the following:
1.
In Control Panel, open Display.
2.
On the Appearance tab, click the Effects button.
3.
In the Effects dialog box, select the Use the following method to smooth edges of screen fonts check box, and then select Standard or ClearType in the list.


If the projected image is dimmer than it was on the laptop, check your projector documentation for information regarding lamp timers. If the lamp life has expired, replace the lamp for maximum brightness.
If the projected image is not rectangular, try one or both of the following:
• Make sure that the projector is perpendicular to the viewing screen.
• Raise or lower the projector.
If the projected image displays vertical lines, "bleeding," or spots, try one or more of the following:
• Adjust the brightness of the image.
• Check the projector lens to see whether it needs cleaning.
• Adjust the sync and tracking on the projector.

VT45 Projector: Blue pixels throughout screen


If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

So, the problem is in the cable - solution is replace cable.
