Cannot get the projector to pick up signal from the computer
This projector was purchased for an association to use twice a year. It has less than 100 hours of use. Sometimes, we have a very difficult time getting this projector to pick up the signal and sometimes we do not.
As of right now, I'm trying to hook this projector to a new Dell Inspiron 1720. I follow the directions by first turning the projector on, then turn the computer on and it will pick it up, but it is not picking up the signal and it says, no signal. I've tried using the USB cable and I've tried using the VGA Cable.
I've tried pushing buttons on the projector to try to get it to run through the source settings again and I cannot get it to do anything!
So, I put the User disk in my computer to go through the manual. This computer reads Adobe 8, it would not read it. It wants Adobe 6. I put it in my other computer that has XP and Abobe Reader 7, still won't read it. I put it in an old computer with windows 98, Reader unknown and I cannot get it to work on there either.
I thought with these projectors, you just plug them in and they should automatically pick the signal up. I've had friends help when we've had problems and they've pushed F? something keys and eventually got it to read. I do not know what those keys are.
I'm very frustrated with this projector and wish I could get a manual to read to figure out the kinks every time we want to use it. Most of all, I have 1 week to get these 2 machines talking to each other.
Could it be a cable?
Any help would sure be appreciated.
PS I should have known. I would have problems with this question too. The projector is an Optoma EP745, but I had to enter another to get it to go through. It is also a XGA, 2500L projector that is discontinued

Re: Cannot get the projector to pick up signal from the...
Yep projectors are just dummy devices but still you have to select the source setting and the type of cable when you connect it to a computer specially laptops, there is a setting on the menu in which you set source to AUTO/or computer on some. For the keys to press on the laptop, press the FN key and hold it down then look for F5 or F4 then press on it it will depend on the brand of laptop but on the F# keys just select the one that has the LCD icon or a monitor icon. Whats your email add so that i can send you lists of these keys to press on different laptop brands

Let me start off by saying that the adapter that you picked up only works on select video cards.
If your computer has an s-video connection, plug your video into that (use an s-video to composite adapter if you need to). If your computer does not have an s-video connection, your best bet is to pick up a VGA converter box. Search " PC to AV TV Signal " to find one.
there is an issue with the power supply edge connection with the main board. you'll need to have it sent to an infocus service center for repair. try av solutions in ny. they're pretty good. www.avsolutionsny.com
Red, Green, and Blue signals come from different wires in the VGA cable. This sometimes happens if a cable simply is not connected fully. But it will also happen if the cable is damaged. The damage might be visible in the form of a bent, broken, or missing pin. Or it might be internal to the cable.
Try another cable.
If that's not it, then the connector on either your computer or on the projector itself might be damaged.
Also try another computer.
Components inside the projector could also fail. But I'd bet on a cable problem any day.
Usually means that the computer is not sending a signal out the the projector via the monitor cable. Most Windows based laptop computers allow you to connect to a second monitor by pressing the Fn + F7 or F8 key, once to allow just the projector, twice to allow both the projector and laptop screen and three times back to only the laptop.
I can almost guarantee that your bulb is out. We probably have 20-30 projectors of this model in the school and bulb life averages a little over 100 hours even though they advertise 3000 hours. Infocus has been known most for their poor cooling system to the bulb over the years and most owners won't get the life expectancy of the bulb. If you remove the bulb you will find a small restrictive vent screen on the bulb and commonly it will be filled with collected dust. This model really doesn't have any removable/cleanable filtering system installed - again a cheap and poorer design then many other brands. We have decided not to purchase infocus projectors anymore in the district. They were a seller at one time because they were cheap, but because they don't last they weren't really a deal after all. Sometimes though a ballast for a projector will go out and it will be unable to power up a good bulb. I wouldn't consider fixing it because of their overall poorer reliability. If your looking for a cheap but more reliable brand of projectors I'd steer towards Epson projectors. They tend to have lower costing projectors and bulbs then most and I have seen in person that they last well above their advertised lamp hours in different models. Their are many good brands out there but InFocus is not really one of them - they have under built projectors and poor phone support.
Hope this helps a little.
