Cannot Connect My Compaq Presario CQ57 to my Epson Powerlite S4 LCD Projector! Help! Please?

I have a USB that has both the USB 1x and USB 2.0 on each end and I plugged both corresponding ends in and let the drivers install and then I put my computer in "Connect to a Projector" mode and the projector still said no signal when i was on ALL the sources. Please help me. This has been a 2 month problem for me. Also, if that simply won't work I have a 15-pin VGA female jack on my computer. So if the USB wont work do I have to gat a VGA to computer component cable?

Hi,
The USB port in the projector is only for Optional Mouse to srcroll down the menu of the projector. Its not ment for the Video connectivity. You have to use 15 pin VGA cable to interconnect the PC and the projector then only you will get the video.

Here i have added the link for the user manual of the projector. Check out page number 30 of the manual.

SOURCE: epson powerlite s4 projector is pink

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the red color has gone out. The image is made up of red, green and blue images layered upon the screen. If the red panel has gone out then there is nothing filtering out the red light in the image. This causes a nice red hue to the whole screen.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

SOURCE: I have an Epson powerlite s4 and a yellowish patch

The likely cause is either dirty optics inside the projector or some of the special mirrors inside the optics are burned. If the projector was used a lot then the special mirrors are probably burned. If it's just dust on the optics the unit could be opened and cleaned but you might have to take it in to a repair place to have that done.

I can't get the display from my laptop to project to a screen.


If you connect the data projector to your laptop and power it up first then your laptop, the video will switch to the data projector automatically.
If you had powered up the laptop first then you can divert the video information to the external video port/data projector by holding the Fn key and then press F4 key.
You can toggle between the LCD screen, the data projector or both LCD and data project together using the Fn & F4 keys.

Images has a blue color across the center


Wow, 3 in a row. As described on 2 other projector issues this is very similar to those others. I'll repeat the info here.

It looks like yours has just a secone of the panel dying or comming loose from it's connector.
