You should not try it for yourself, Call a Professional instead.

Just went through this issue with a 1200MP. The cause of the failure was a failing optical speed sensor on the color wheel assembly. It overheats and produces an invalid signal shortly after startup, causing the projector to shut down. The good news is that this is a $2 part. The bad news is that I wouldn't really call this a "DIY" repair unless you have the ability to unsolder and replace tiny surface-mount electronic components. You will also have to do extensive disassembly just to get at the part, which is buried inside the optical system. I am a professional electronics tech, and removing/replacing the part took me about 2 hours on a fully-equipped workbench. Troubleshooting the unit to FIND the failed part (without any service manual or schematic) took another couple hours, FWIW.If you want to give it a try, the part you need is a GP2S27 "photointerrupter" manufactured by Sharp. These were discontinued a year or so ago, but some distributors still have stock (get them while you can). I got mine from DigiKey. This is a tiny little part about the size of a match head, with 4 terminals that need to be soldered onto a small circuit board, after removing the old part. You will need a steady hand, a fine-pointed soldering iron, and a magnifier with plenty of light.Good luck!

remote wont click to next page on Powerpoint presentation

Mac will have an adapter on the display output in which you will connect this to a VGA cable and to your projector.

<FN> then, <F4> or <F8>, may have to try 2 or 3 times to get the right setting. Hope this helps

Hi.

If you have a replacement cable test the DVD using a different cable, you never know.

Try the following:

• Unplug both projector and DVD from power.
• Keep units connected together by video cable.
• Connect back and restart the DVD first.
• Restart the projector only once that DVD is ON.

If it still does not work , then there may be a fault.
