Re: Infocus 5700 new lamp unit makes variable blowing...
I've seen this problem several times with the fan that is on the fan. For some reason the knock off lamps have bad fans. Just clean up the fan from your orignal lamp and put it on the new lamp housing.

there is more than one fan inside. one of them may not be working. also, if there is excessive dust inside, the heat won't leave. blow out all of the dust with canned air. if one of the fans are running slow, replace it. lastly, do not use an aftermarket lamp. get a good one from the comapny.
the bulb may have burst from overheating from a fan not working to cool it down. and it can be replaced. it does take, however, a while to replace it because you have to take half of it apart. but make sure it's the fan first. take the lamp door off and remove the lamp. use something small and thin to push in the switch that the lamp door usually activates. turn the projector on and see if the lamp fan and the colorwheel (the multicolor glass disk) are spinning. if the fan spins, the noise may be from the colorwheel motor going bad. the fan can be purchased through an infocus authorized service center. check the website for the closest one. but the colorwheel for the x1 cannot be purchased seperately from the optical engine, and that costs a fortune. but here is the part number for the 80mm fan- 526-0152-00.
The fan is probably on it's way out and cannot produce enough air flow to cool the lamp. Replace the fan with the same ratings as the original and it should work fine. The only other thing would be a problem with the power supply not supplying enough power to the fan, but, a bad fan is more likely.
Because these units have dangerous high voltages inside, there are a number of safety interlocks throughout. Take out the lamp and reseat it. Also, make sure that the access door is installed correctly and securely. Both have interlocks that will prevent a poiwer up is not installed correctly.
If this is not the case for you, please update this and we'll look for other causes.
first off, make sur you have the right lamp (sp-lamp-009, 2 white wires. not the sp-lamp-018, one white, one red. the wires are in different locations in the plug). if you don't hear the colorwheel whirring, that'd be the next step. however, you cannot buy just the colorwheel. infocus does not sell individual parts of the optical engine. but that wouldn't matter, seeing as how they don't sell the engine anymore. also make sure the lamp door is completely closed. there is a peg on it that activates a switch to let the projector know it's closed. if you remove the lamp and use a flat-head screwdriver to activate that switch, turn on the projector. look inside the lamp housing and see if the colorwheel spins. if not, i think you need a new projector. if it does, check the fans. they can be replaced.
I've got the same problem, I'm wondering if it has to do with some sort of auto shut off kicking in due to overheating or something, I was gonna try replacing the fan to see if it's something to do with that
