Question about Dell 2300MP Multimedia Projector

1 Answer

I just changed the bulb but the unit will not power on. I can hear clicking as if it is attempting to power on.

    Great idea, but I tried this and it still won't power on. It makes a quiet clicking noise, just like a computer's hard drive working. It does this for about 60 seconds then the "lamp" warning light comes on again.

The problem with the bulb cover interlock(safety switch) tab is that it is molded with the plastic cover. When these projectors are ceiling mounted upside down, the heat from the bulb melts the interlock tab and causes it not to actuate the interlock switch.


If you push the switch arm in you can hear the switch click. The fix I did on my projector was to bend the switch arm so that it stays actuated. You can use a small set of needle nose pliers or two small screwdrivers. be careful to only bend the arm in the middle, if you break the arm from the switch, you will have to go in and bypass the switch.... Just be carefull...

After you bend the switch arm try to press it in, if you did it right you won't hear the click. install the lamp, cover, and your done.

    Had a similar problem and Dell tried to get me to purchase a "genuine" Dell lamp. Turns out it wasn't the actuator switch but the mount for the power interface was cracked (probably also from prolonged heat). When I tried to insert the new lamp it pushed the power interface down into the housing and never made decent contact. I unmounted the power cords from the lamp to extend the cable, connected the power couplings manually and then mounted the lamp, stuffing the power cords back into the housing making sure they don't contact anything hot. You can look through the grille with a flashlight for visual confirmation. Like magic, my non-geniune lamp works fine. - DW

Hi Isnovero,
The main reasons of your problem is the bulb which is already came to its end. The unit will automatically shuts off when it sense a bulb failure. But before you replace the bulb I would advice you to work first on its power supply. Look for open fuse/fusible resistor and spot some bad solder joints. This will do the same symptoms like what it showing now. If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.



Hope I helped you.
Have a nice day! Thanks for using Fixya.

Unfortunately lamps go bad without the visible state of being bad. I don't know who or where you bought the lamp from but I order all my lamps through dlplamps.com
The clicking sound you hear is the lamp inverter igniteing the lamp but the lamp is bad.

I just ran into the same problem on my Liftmaster 2265R. Identical symptoms, but I haven't attempted any remedies with the bulb sockets yet. I shot an e-mail off to Chamberlain's tech support people. I'll post again if I get an answer from them or discover a solution. Please do the same if you find something. Thanks.

Panasonic LiFi model number PT-50LCZ70. Have red lamp light flashing on front 2 times. Have tried to turn it on and get no picture and no sound at all. I checked and the fan is running. What now?


After the red 2 flashing starts, press the power button on the front of the TV and hold pressed down for ten seconds.
You will hear a faint click comming from the back of set.
After 10 sec release the button and wait 10 more seconds then press the start button and release right away.
The green light flashes and the bulb attempts to start.
I found my picture will turn on on the third attempt of the bulb restarting.

When you do this and the room is dark you can see the bulb attempt to restart, My bulb has restarted on the third restart every time.

(note: The three start attempt happen after I do the button pressing
1 time and I do not need further button pressing restarts.

I think panasonic needs to let us know what the problem is.

I called Panasonic and they told me to plug it into a wall plug by itself.

I have it plugged into a multi plug adaptor now and have not tried this yet.

This sounds like you will have to replace the logic board. Whether you repair or replace get a surge protector 900 joules or higher unless you want it to happen again. You can get replacement parts at searspartsdirect.com. Thanks BB

How do I test the bulb?


Pull the bulb housing out of the side of the unit and look into the bulb, you will see that it has shattered into pieces inside. Right or left side of unit is an access door with a few screws, loosen and remove the housing holding the bulb. matelectronics carries bulbs.
