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

SOURCE: Infocus lamp not firing

more then likely the ballast has gone bad and the lamp is not getting the right voltage to fire. Only other thing you can do is remove the lamp the turn the power on and check the voltage at the connector. This will not check the triggering voltage mine you only the lower operating voltage. But since you have replace the bulb with a known good one I'm betting on the ballast is bad.

SOURCE: infocus sp5000 red led blinks once indicating lamp

be sure and reset the lamp hours. Flash the software if you can. These are also notorious for the ballast cable on the inside of the lamp housing backing out when a lamp is removed or replaced. If you have the cover off push the cables back into place and hold them there as you install the lamp. Also look directely at your lamp in the center and move it side to side and up and down. If there are any cracks or frosty looking spots or bubbles in the mirror of the lamp that are visible, then the lamp is probably shot. If all this fails, most likely it is the power supply, or the lamp door has gotten mishapen from heat and the actuator on the lamp door isn't making full contact with the safety swith.

Ballast issue on LP640


first off, many churches and schools hang their projectors from the ceiling, and the only time they take them down is when they don't work. it sounds rational, but it gets dusty up there, and without proper and relatively frequent cleaning, the dust builds up and the projector can't release the heat properly. this causes a lot of malfunctions. the ballast is only one of them.

to replace the ballast:

make sure you can get the part from infocus or an authorized service center. it's part # 525-0085-51. after you remove the cover (4 screws on the bottom. you'll need a T10 torx driver. slowly slide the top forward and lift off), gently remove the ribbon cable by sliding the cable locks (on both sides of the cable) towards the front and pulling the cable out. the ballast is at the front of the projector next to the lens and in front of the lamp. pull it out and remove the ballast from it's housing. there are 3 cables coming off- the power plug, the lamp plug, and the lamp enable plug. remove those and replace the ballast. reverse the steps to install.

InFocus LP650 will not come on


First try a firmware upgrade. If that doesn't help, it seems it might be a power supply issue since you said the led comes on very light. I repair these power supplies. My ebay id is gtitubro

Infocus LP540 --- display


Hello,
It sounds like you may be feeding it with an HDMI source using an HDMI to M1-D adapter...

If this is the case, make sure the source in not set to a resolution higher than 720p.
However I really need more information to offer a definitive solution.

Take Care!

InFocus LP650 will not come on


That color is not listed because it is either Green or Red. There is no Blue, if you are getting Blue, you have something that is extremely unusual.

LP540 INFOCUS


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.
