Two gigs in a row one of my Dell MP2300 projectors is acting up. I plug it in but it wont turn on. I mess with the power cord for about 2-3 minutes and finally it will power up. It's turned off on it's own once (before the gig luckily) but typically once it's on it's on. I'm sure it's a loose connection with the power plug but leery of opening it up. Any experience with this problem?
Projector problem. Any advice?

Not to undermind you, are you pressing hard and firmly the IEC cable into the power socket? Are you using the IEC for the projector or just a loose one, have you tried vice versa of that?
Check to make sure your fan is running on start up. I'm having a feeling your fan isn't running and the unit is going into thermal shutdown.
Travis, I've used the origional and other power cords, pressed firmly, upward, downward, half in, half out, I've put my left foot in and my left foot out.....
JT, not a thermal mode problem as once thought this is happeneing before the unit even turns on...it's definetly a power issue. Fan runs fine and stays on unless it loses connection with power for some reason.

dang....I should have read your original post....
hmm.....
I'd open the back and check solder/blade points at the power supply....

You forgot to
you shake it all about.
You do the Hokey-Pokey,
And you turn yourself around.
That's what it's all about!
I guess we can see who here was a skating rink DJ ;-)
Just Pickin.... Seriously though, I concur with JT, i have seen issues with IEC cords before, and wiggling the connection gives an "pop". I would however say send it in before you break it apart, unless it is not under warranty.

You think? It won't turn on at all. But once on runs flawlessly and as bright as ever.
No it's not under warranty anymore but only has about 30 hours on the bulb!
Usually projectors will notify you of a bad bulb. I've never seen any projectors bulb go out that quickly, unless it was on and fell, or roughly handled on the road... Even then I NEVER have seen a projector go bad just like that.
It is a common way for such a lamp to go. We have seen it in projectors & followspots &..... Just had a followspot lamp go out as it would happen. Typically, if your lamp is near or over rated hours, it will fail to light. You may get it to light, but it may power off again after a short time (because an aged lamp draws more current and the power supply will shut down). A lamp may not reach its rated hours if it is cycled on/off frequently, particularly if you don't leave it on at least 20-30 mins once lit before powering down. Doing otherwise shortens its lifespan significantly. Dirt in the projector can cause unnecessary heat which shortens lifespan. (check your filters).
If handled well, it is common for lamps to outlive their rated useful life; but use caution, because as you approach the end of hte life in a device such as an LCD projector, a lamp failure can mean an explosion of the lamp. In some devices that's no big deal. In something like an LCD projector it can cause damage to LCD panels.
Our spot that just went out failed to light. It would after many attempts light, but the spot would power down after a very short time. The lamp was about 30% over its rated life. A new lamp and all was well. I've seen the same in projectors on more than one occasion (at least 3 come to mind right off-hand that I personally know of).
So yes, I think it could be!

I get nothing, not even an a blink from the two indicator lights on the top when the projector is first turned on. Today when it turned off after being on for about 10 minutes the whole unit was completely dead...no power at all. After some messing with the cord it decides to come back on and last through the whole movie.
I think I'll open it up, check the solder points on the plug in, if they look good try swapping bulbs with my other unit and go from there.
Val hmm with your experience over how many yrs I bet you have the best idea of any thus far. Of course perhaps all those yrs really dont mean anything (J/K) hopefully you got my humor.
Just a thought, Travis I'd like to know what you think about this. Could the fact that I was running both projectors off a 100' extension be to blame? The cord was a nice 12 guage big boy, could it affect the power draw just enough to "confuse" the projector? I'm going to test and play around tonight. Just wanted some feedback going in.
get a multimeter and test the ends to find out if this is true. Undervoltage could happen, but I doubt it. You usually see that on longer runs.
generally speaking as Travis mentioned unless you are using a utility Christmas tree type ext. you can run a industrial style cord of 100 ft or less.
thanks you two, good to know. I didn't think that would be the problem but you never know right. I'll see what I come up with tonight. Thanks agian.
