Hi Mario

If there is no response on the Projector it normally means that the Mainboard is faulty.

Check if your machine is still under warranty because this quite expensive to replace.

As far as the schematics are concerned - I'm unfortunately not able to help you out with that.

I think that its a port issue, if all the other ports are working but hdmi is not then one of the pin on the circuit board may have come loose. I have the same issue. Could try to solder it back on or use a glue gun. let me know if this helps?

There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/ Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

Hi Becki. Projectors will usually be identified on your computer as additional or optional screens/monitors. Depending on your setup (laptop/desktop) you may have some alt keyboard buttons with icons for single/multi screens. You will also likely have monitor control panels or non-windows equivalents. In Windows, for instance, right-clicking the desktop will usually bring up a monitor properties page. There you may be able to then select if the projector is a mirror of your desktop, an extension, projector only, or computer only. if the computer says it sees the monitor, then you'll likely need to toggle whatever sort of menus the projector has to select the input port. Looking through the manual ( http://www.hitachi-america.us/supportingdocs/forhome/DisplayTechnologiesGroup/lcdprojectors/SupportingDocuments/cp-x251_um.pdf ) , suffice to say that there are multiple ways to connect and, with that, plenty of ways to have your cable be hooked up and ignored nonetheless. Hoping this helps! D

From your description, it sounds like a problem with the blue color. Green LCD=purple onscreen, Red=cyan(baby blue) onscreen, Blue LCD=yellow onscreen. It could be a lot of dust on the blue lcd panel, or worse, might be a burned polarizer filter behind the lcd panel due to excessive heat. If you can focus on the yellow and its tons of yellow specs, its dust. A burned filter however, must be replaced. A technician trained in projectors will have to do it. The filter material is glued to a thin glass panel and is replaced as a single filter. It's a very involved repair.

Inside the main power supply. However if the fuse blew out something caused that. be very careful. Fuses do not fail on their own.

The ballast (which provides power for the lamp) might have gone bad. Check the voltage its outputting with a digital multimeter.

Hi, you can be able to use that old projector. for that you need an "HDMI TO VGA" converter .Have added the picture. you can find it in any computer accessory showrooms or you can buy it online. www.electro-medical.blogspot.com

Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

• A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
• A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.

Goodluck..
