That was it for me! I took some needle nose and pulled the projector connecter back into it's slot. It had fallen down past where it should have been.

Re: Error when powering on the projector

You need to make sure that the wiring that connects the power from the project and the bulb is touching. You may have to take off the top and press on the opposite end of the connection as you put the bulb in.

Good Day, I have 3 sony ex3 projectors - 2 of which have an intermittent lamp/cover error where the lamp/cover led blinks and the machine does not light. The problem is still there even after i press...

The small lamp cover dimple that is supposed to activate the protection switch doesnt reach the switch if the cover is slightly curved due to age and heating.
So I put a small dob of silastic on the dimple of the lamp cover and let it set for 24 hours. Then I put the cover back into the unit and all is OK.

In your testing, make sure you are pressing the switch down manually before you power up the unit.
Then the error message is not likely to be a cover error message.
If you still get the error then I would check the integrity of the switch mechanically and electrically. Check that the connector from the switch to the pcb is OK.

Dell 2300 projects verticle stripes accross the projector screen.

this is due to improper power supply or a loose connection inside. the symptoms are of power supply unit inside projector. check out the current and amperes inside the projector on board. sometime the current stable but the ampears are down.also check the switching transistors & filters inside.......

Lamp will not strike error message

this can sometimes indicate either an overheating issue, a lamp service life problem, or that the cover to the lamp housing has not been secured properly.

Faded Black Strip on Side of Projection

I had a similar problem with my InFocus LP600 although my black stripe was straight up and down. I am guessing this is caused when the unit is bumped or dropped. This is not an easy fix unless you have a lot of experience with small tools and parts and you may need an extra set of hands. I found some tiny alignment screws under the lamp cover and hidden beneath a peel-off 0.5" x 2" black plastic strip. The screws are located between the bulb assembly and the main projection lens and are oriented 90 degrees apart around the light projection path. The trick is in getting the projector to temporarily function with the lamp cover off -- it has an interlock tab on one edge that pushes on a microswitch when closed. We turned the projector upside down but raised on some slats for heat dissipation, gently held the interlock switch in with a small screw driver, and plugged in the power cord. After pushing the power switch to get the image, I adjusted the tiny screw that is angled towards the front of the projector and the stripe dissapeared! Since your stripe is angled, you may need to adjust both alignment screws. The screw heads are very tiny torx bit types but I was able to use a 3/64" (.05") allen (hex) wrench that came in a set of cheap jewelers type tools that are widely available. Be very careful while operating the unit with the lamp cover off as there are very hot surfaces and exposed wiring.
