Projector will not power on

When I plug in the power cord the projector has no power. No light, no fan movement, nothing at all. I was wondering if there is a fuse I can replace or if the systems board will need replacing.

Projector will not power on!
I just changed the bulb and now the projector will not turn on. It ran for about 5 min but then had lines and a black section in the picture. After the 5 min the projector shut off and then never powered back on agaib, could it be the fan???? I have an Infocus 4805

Re: Projector will not power on

Check your cooling solution wether its a fan malfunction or if it needs a new fan - or h20 cooling system

if not its either the power supply or something serious - send it to manifacture or go to a in-store repair

(it could be the dust protector)

My projector won't turn on, only the power light shows red, the status light is blank. Tried the remote and manually turning it on.

If the power light is ON and status light is OFF; check if any objects are blocking the air inlet or outlet grill, and remove them if any, and carry out the following.
[1] Unplug the power cord from wall outlet.
[2] Make sure that the projector has cooled off.
[3] Plug the power cord into the wall socket.
[4] Press the power button.
Check whether the cooling fan has stopped. The problem is with overheating itself.
If these does not help you, your projector need service. OK.

Projector will not turn on. The power light is solid Blue and clicks every minute or so like it is trying to start but nothing happens. It has happened to two projectors. I am baffled as to the solution....

I too have to same problem, did you find a solution? I swapped out the existing fans with different ones to try to solve the problem to no avail. I inspected the bulb for signs of malfunction and could not find any. Any updates would be wonderful!

Projector not booting up


The projector may not be receiving power or it may be malfunctioning. Turn the projector off and unplug the power cord. Confirm the power cord is securely connected to the projector and then plug the cord back in to a different outlet and turn on the projector. If this does not solve the problem, and another light is on or flashing, check the projector’s status.

Hope this helps

The power supply of the lp640 has a protection derived by the functions of TOP 2XX witch in overload stops. therefore disabling the shorted output.
Verify the state of the fuses also.

Good luck out there ,
