Contact the manufacturer for a firm ware upgrade. My two brother in laws/sisters own this same pj and had the same issues you are talking about. Once they installed the update [aka: firmware upgrade]it created a solution to the problem.

Let me know how it goes. They can either mail you a CD, direct you to where on their website, otherwise email you the update to download. You have to connect your pj as well.

Let me know how that goes. I'm fairly confident that will fix it. There was a certain time frame [manufacturer dates], and serial numbers that had these issues.

InFocus ScreenPlay 4805 no projection. Unit powers on and green light blinks, but no light and no fan, eventually red light blinks continuously about 2 seconds between blinks. When the green light is...


the high-pitched sound is the colorwheel trying to spin up to speed. that may need to be replaced. check the inside of the lamp for bulges, black spots, fogging or flaking. if it has any of those, replace the lamp. you can get parts from an infocus service center or send it to them for repair. either way, try www.avsolutionsny.com they're really good. if you want to replace it yourself, there is a detailed step-by-step on my "tips" area. it's the same as the infocus x1, x2, x3 and sp4805. click on my picture and scroll down to tips. good luck!

Infocus 4805 Lamp will not ignite after new bulb and reset.


it there is no high-pitched squeal when it starts up, the colorwheel needs replacing. the lamp won't light without it. the part is under $50, but installation is quite involved.

In the manual there is a chart which will indicate the nature of the failure depending on the number of times the red led flashes before a pause.

Most common is the projector's lamp timer has exceeded the operational lamp time limit.

While the projector's red led is flashing, press the volume up and down buttons on the projector simultaneously and hold them both in for 10 seconds.
This will reset the lamp inhibit protocol.

However if the lamp has thousands of hours of use you need to replace it before it actually fails.

I turn on the 4805,green led blinks & bulb does not come on?


After a few minuets does the green blinking light turn to a red blinking light?

If so the problem is the lamp did not strike.Either the lamp has failed (most likely) or there is a problem with the power supply (less likely)

Infocus 4805 blinking red light problem


My first questions is:

Is this the first lamp you have placed into your Infocus pj? If not, did you reset the hours when you did it last time? Otherwise that can also confuse the projectors internal system thinking there is NOT a new lamp in there and there for make it stop working once the clock hours are expired and over the 3000-6000 suggested hour life.

Let me know so I can help trouble shoot other possible problems.
