    When I turn my InFocus SP4805 on, cooling fan starts, it beeps, red light comes on, a hiden light can be seen though the lens but no light comes out.

    Seems that the bulb does not start properly.

    Some minutes after the lights goes off! but the fan and green light stay on.

    My projector has less than 20 hours

    Need more details? Please help!

Hello everyone, 3 months later, after much time to research the problem on my projector, I finally managed to solve it and everything works perfectly. Here's what I do:

-One day, I turn on my projector and it was a funny noise (buzzing noise). I turned off and then I turned back. More picture and sound was still in office.

"I sought what could be the source of the problem. I thought a moment that it could be the color wheel. My son is hitting your site. After long trying on solution that you give, no results!

"I open the projector to clean it (with great difficulty) and then I clean. Remember that in the instruction manual, it is clarified to remove the lamp and clean the air filters for better ventilation of the lamp after 250 hours of use!

"I closed everything and projector Do not! So I thought it was the lamp that was broken. I buy a new lamp and after installation, the projector is still running NOT DO!

- I looked for a new projector .... 3 months later my son was tired of not having big screen so he returned to this site and reread and reread all the tricks. It is dropped on it: KEEP YOUR FINGER FOR 15 SECONDS ON THE BUTTON CHANNEL! I quickly realized that it was''buttons''KEYSTONE He turned on the projector, press both buttons magic and then ... LAMP lit!!

"I dropped the search for a new projector!

This projector has given us many problems but it works well. I will give you news and also because I am very curious!

Thank you and good end of the day

Odd problem with ceiling fan and LED

This is a common issue with LED bulbs in the application that you have it installed in, When you changed the socket it reset the unit. Most of those wont ever see an LED because the LED wont draw enough current. Then control box depends on a current draw in order to stay on. LEED bulbs don't have enough current draw.

Projector will only stay on for a couple of minutes then shuts off automatically. the LED turns from green to red

Make sure the venting for the cooling fan is clear and that it is activating. The only time I have seen this in a projector is when it overheats. If it reaches a certain temperature and doesn't sense the cooling fan being on it shuts down to protect the bulb and protect against fire hazard.

Gateway 503gr has no power, the standby light flashes green when I remove power. Tried new PS and the standby LED stays lit. I then tried both new and old PS disconnected from board and shorted...

Disconnect everything from the motherboard except the power supply connections and cpu fan. Install one stick of RAM and connect your monitor. Then try starting up. See if you get any BIOS boot messages. This will tell you that the board and processor are okay.

With what you say you've tried already, I'm thinking you might have a bad processor. Most every other problem would result in some kind of error like POST beep codes or messages on screen. If the system still doesn't boot with the bare minimum parts installed, replace the processor.

Unit will not turn on

did you turn it off or unplug it? not to sound too obvious, but make sure it's still plugged in properly and the switch is on. if the led is lit on the top, it's getting power, so it's not the fuse. if not, the fuse is located on the power supply board inside the projector. if the led is lit and the fans don't turn on, it still may be a power supply problem. if the fans go on and not the lamp, could be the lamp, ballast, or main board. if you need to send it in for repair, try av solutions in ny. they're really good.

Projector goes POP!

I think it's the bulb, the best would be to take it to the shop where you bought it - or any other good electronic goods shop - so they can test it. If its still under guarantee its better to take it to the dealer. Mine had to have the bulb replaced after only 8 months, but it was still under guarantee.

SP4805 bulb does not fire up; led stays green; fan turned on

I had the same problem after purchasing a new bulb. My husband pulled it out after it would not fire up and the new bulb plug in conecter (white with 4 holes with two wires) was different. Take your old bulb and compair the two conecters and see if they match, then check if the wires are in the same slots as in first and last. Mine on the new one were in the first and second to last slot. So we took the wire out of the second to last and put it in the last slot and installed it and it fixed the problem. We also had to unplug and replug it in and do a master reset by pressing the Power and Channel buttons and the same time for 15sec. Hope this helps.

Good Day, eger00;
Try this:

First, some clarification related to this Flowchart is necessary. The block which states * PSL #4 pin Voltage sequence is like below? a) high (3s) b) low (3s) c) high (15s) d) low (3s). This indicates seconds in which the ballast is attempting to light the Lamp. The Connector PSL is a very small connector that actually faces down with the ballast is installed. It is also very difficult to access. It's much easier to use the Spark Gap process for determining if the Ballast is attempting to fire up the Lamp. Take a look at the bottom of the flow chart below. If the Spark Gap sparks when trying to turn on the set, it's almost a guarantee that the ballast is working OK and it's the Lamp that's defective. Also, the LEDs on the front of the LCD will flash in sequence Left to right as this process is attempting to light the Lamp. The front LEDs doesn't guarantee that the ballast is functioning correctly, but it does indicate the System Control process for lighting the Lamp is working.
