Projector will not detect input and shuts off changed bulb and temp light still flashes red
First thing to do is tackle this Temp warning light. Check if the projector has an "Auto Off" feature. This is where the projector shuts itself down after a set period of time when there's no signal. If it has, and it's set to on, then switch it off.
Next, clean any filter(s) and vents. Use the nozzle attachment to the vacuum. You're making sure that the projector can breath properly.
Now, input sources. If all fails, go back to basics. The yellow composite lead is about the simplest video connection to make and it's pretty fool proof. There are plenty of devices that give a composite video signal e.g. DVD player, camcorder, Freeview box. Use one of these devices and connect up the Video Out from the source to the Videio In on the projector. Fire up the projector and select the composite video input. The picture won't be as clear as a PC signal, but you should get something.
Once you know that the projector is working with a video input, and it will stay on, then you can concentrate on the PC connection.
Every laptop has a facility to toggle the display from the screen to an external display. The exact method varies from brand to brand. But they're all a variation on the same theme. It's the Function button (Fn) and one of the F keys. On my HP its Fn + F4. I've had laptops in the past where it has been F5 and others that were F8. All of them though had a little symbol representing a screen on the correct key.
The way it works is that the laptop screen is on. The first press of the two buttons will put both screens on. The next press is just the output to the projector. The final press brings it round to the laptop only again.
Once you have just the projector running, then you should change the display resolution to suit the projector if the laptop hasn't already done it for you. You can tell when it's wrong because the text won't be crisp. Right click on the PC desktop and then select "graphics properties" or similar from the menu. Change the resolution from the drop down box. Click OK to confirm. The correct resolution for a projector is the native rate. This is the number of pixels on the display, not the maximum resolution.
