Question about InFocus LP 820 Multimedia Projector
It sarts just fine then it shuts down after 30 seconds and says fan stopped . Infocus wants to charge $300 plus $30 to ship to them to replace the fan. From what I can tell all of them are working has anyone else had this problem and if so what do I need to do to fix it
This could be one of two problems I have seen with another model Infocus projector (they are very good projectors though)
The first is the video input. Make sure it is attached correctly at both ends of the cable.
The second, remove the dust covers and blow them out. The problem can arrise if the temperature sensor detects the air inside the unit is getting too hot. If you can see the sensor when the dust covers are off (it will look like a little lump of goo on the end of a wire) then just give it a wipe as well. If dust settles on those it can cause incorrect temps to be reported.
Hope that solves your poblem =)

The USB cable doesn't transmit Video. You need to plug in the VGA cable. The "DVI" port on the LP820 is not a a DVI but a M1 Digital port and won't work with DVI unless you get a converter.

SOURCE: lp820 infocus will not turn on
Some capasitors should be changed in the powersupply and several diodes too, may be. There are temperature mode in the power supply is very hard and those capasitors broke from that. Therefore running of projector is not stable. However if dont change capasitors at time then one diode may be broken and the projector will not start afterthat alwase.
Its not so big work for repaire.
I hope may english is understandable for you.

there is a problem with the power to the front fan from the main board. there are 3 wires going to the fans: one power, one return, and one signal. if the main board reads no signal from the fan's speed, it'll shut down. check the power going to the fans and the signal. you may need to replace the main board.
