I own a HP MP1900 projector and it wont turn on anymore...the bulb does not look blown and it never gave a going bad msg?

First check that the plug is in the socket and the power is switched on. (don't laugh, a friend did that just last week!) Next check if the fuse in the plug is OK. If you have no spare fuse try swapping one from another plug that you know does work. Next check the projector for signs of an inbuilt secondary fuse. These are often a circular access about 1to 1.5 cm across that screws out of the body of the projector. Hopefully one of these may cure your problem.

Does not power up. LED light near plug on on &

trouble shoot it first before we say that it is power supply, disconnect and connect it to ac sourece, press the power button, if no effect, it is power supply, but if the fans work, replace or check the vga cale to monitor, or the monitor itself

I have an Compaq MP1400 projector not working

Hello :

1:Remove the lamp from the projector. Ensure that it has no cracks, discoloration or "smoky" appearance.

2:Try removing and reseating the lamp, or to try another lamp.

3:Reset your lamp timer. Most projectors have no way of knowing if you physically have replaced your lamp or moved it out . They rely on the user resetting the lamp timer

4:Pull the lamp back out of the unit, give is a brisk shake and reseat the lamp. Occasionally there is some buildup on the lamp contacts or filament during manufacturing.

5:Are the input and output vents blocked or obstructed in any way? That could cause overheating problem and what you see with your projector is one of it's symptoms .

6:Are the filters dirty or clogged? Most manufacturers will recommend filter cleaning on a monthly basis depending on usage .After cleaning the filter always remember to reset your projector .

7:Remove any extension cords, power strips and/or surge suppressors. Many current model projectors will not even try to ignite the lamp if they detect drops or fluctuation in voltage supplied to the unit. This is a safety feature to reduce stress on the lamp.

Do you know where i can purchase a power cable and manual for this projector?

You can download/print the manual by following the link below. I can't tell from the pics what type power cable the unit uses, but you can likely purchase one by contacting COMPAQ customer service through the web site Hope this helps.

Most likely a bad cable. Try bending a little bit of the wire at a time and see if the color flickers back to normal, or you could just by another cable and see if that fixes it. Happens to a lot of the projectors I support.
