One blink led - PJ won't work

Hi

I having problems with my 4805. Was enjoying a movie, when the lamp suddenly shut down. After that nothing. When I turn it on I can see that the lamp shortly lights up after that shuts down. This is repeated five times and led goes into one blinks. The manual says:

One (1) blink The lamp won't strike after five (5)
attempts. Check the lamp and lamp door
installations for loose connections

Any ideas on how to check for loose connections. Double check the door, even cheated by pushing the metalplate down with a oen while the lamp was connected but outside its housing...

Any thoughts would be greatly apreciated.

New bulb worked for a short trail run now wont light up. flashing green led colour wheel is turning on start up


when you changed the lamp, did you blow the dust out of the projector? if the screen on the side of the lamp is blocked (i.e. with dust), the lamp will blow quickly. if the projector were to overheat, by the fans not running or blocked vents, everything would shut down and the led would blink red.

4805sp runs 4 or 5 minutes then shuts down


could be the fan should be running to cool the lamp. there could be temperature sensor that is why it is shutting down to save your lamp.

check the fan if it has continuity. it could be broken and need to be replaced.

Projector was turned off wrong and now wont turn back on.


if the led flashes once in 2-second intervals and you don't hear a high-pitched whir, the colorwheel needs replacing. if you do, the ballast is bad. if it flashes 2 times, the lamp is past 3000 hours. 4 times, fan error. 5 times, temp too high and it needs to cool.

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 - Doesnot display and make noise at start-up


Well a single red blinking means the lamp won't strike after five (5) attempts. The "squeaking" sound if it's coming form the large fan usually always means the Mos-Fet fan speed controller chip has failed which presents sometimes as an intermittent squeaking sound. Which would implies the lamp may have failed from the resultant over temp. However if the squeaking noise is coming from the color wheel that would mean it's bearings have failed and if is is unable to phase lock at reference speed the lamp would also not strike. The odd symptom is the remote thing... That does not fit! If is actually is related to the common cause of all the problems... That leaves only the power supply has partially failed (not too expensive) causing all of these symptoms.

Or murphy has moved in...

Good luck!

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.

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.
