LP580 not powering up

I have replaced the lamp on my INFOCUS LP580 and I have followed the powerup procedure but not even the power supply fan starts. Is there something quick that I can check for . . . maybe a fuse?

Lamp replacement issue infocus in24+

either the lamp's seams aren't taped over with foil tape to prevent the premature shutdown due to the heat sensors being triggered, or the fan under the the colorwheel has stopped, maybe due to a piece of lamp from a previous lamp explosion being stuck in it, or the power supply/ballast is bad, or the eca on the engine itself is bad. The lamp is the easiest to try first. There should be foil tape over the seam on the side of the lamp you can't see when it is installed. If this doesn't work, take the front bezel off amd get where you can see the fan under the colorwheel and tunnel and power the unit up and see if the fan comes on. If it does thenthe eca on the engine or the power supply ballast is most likely bad and these are major repairs.

Infocus lp420 powers on (can hear sound) but no

if you get no leds, it's the power supply. if you get fans, it may be the colorwheel. if the colorwheel is ok, it's the ballast.

My infocus will not come on. the red light blinks. change the bulb but didn't do any good

check the colorwheel. if the colorwheel doesn't spin, the lamp won't light. if no fans come on either, replace the power supply.

I want to test my infocus lamp to know if it is burnt

Your lamp might be ok, but you power supply is dead. If your not seeing any led lights come on when the power cord is plugged in then your power supply is dead. I can fix this for you for less then it cost to send to infocus or to a repair shop. Ebay Id is Gtitubro

good luck. not even the infocus authorized service centers get those. besides, they were made by another company that does not make power supplies antmore. and infocus doesn't have any new ones in stock. if you're getting no power at all, replace the mosfets. it works half of the time.
