I have an Infocus G300-ww

In the Infocus IN1 G300-WW projector the problem won't turn on, is not with the lamp or configuration, it is the Power button that internally breaks a plastic tab and does not make contact at the ignition point, you just have to disassemble the upper plastic, look for the plastic part of the Power and put glue on it so that it is the same as the other volume and light contacts. The projector is reassembled, it is connected and the Power is pressed, so it should turn on and give the image. This fixes the Infocus IN1 G300-WW won't turn on problemEn el proyector Infocus IN1 G300-WW el problema por el que no prende o no enciende, no es de lampara o configuracion, es el boton del Power que internamente se le rompe una pesta?a de plastico y no hace contacto en el punto de encendido, solo basta con desarmar el plastico superior, buscar la parte plastica del Power y ponerle pegamento para que quede igual a los otros contactos de volumen y luz. Se vuelve a armar el proyector, se conecta y se oprime el Power, asi ya debe prender y dar imagen. Esto soluciona el problema de encendido del Infocus IN1 G300-WW

I have an IN104 InFocus projector. the whole unit cuts off without warning or any indicator lights, messages or whatnot. Says there's only 118hrs on bulb

Check the caps on the power board inside the unit. You probably need to recap it. I had that problem on one of the smaller projectors.

Fan wont turn on infocus x2

This problem is almost never the actual fan itself failing..
The intermittent whine you hear is the result of the Mos-Fet fan driver chip which is the speed control current amplifier.
It's an 8 pin surface mount chip on the bottom of the main (lower) circuit board. This is a common failure with these projectors.
The chip is inexpensive and needs to be replaced by someone who is skilled in surface mount component technology. You can replace the fan but you will still have the same problem. Hint, the bad chip is not the one closest to the large fan connector... It's the one closest to the small fan connector and it will measure 45-60 ohm's between pins 7 and 8. the part (rns70d) is discontinued however there is a replacement that can be purchased at...

I have an InFocus LP600 projector. When I apply power the fan comes on but nothing else. No matter what button I press, nothing. Any ideas?

if the fans run, then ,check the lamp or lamp ballast turn on the projector ,at the same time ,if you can hear a continuous beep beep sound (the ballast igniting the lamp) means the lamp may be fault,and other parts is working well I am an expert of repairing projectors for 19 years.
