PJ458D Displays Multiple Lines and scrambled picture
My projector recently started showing horizontal lines across the screen after it has been on about half an hour. The lines flash on and off and get bigger. It looks like the "white noise" image on your standard television if I leave it on about 45 minutes. I've stopped using it. What's wrong and how do I fix it?

White noise-the image you get when you turn your television to a channel that isn't receiving a signal. Sorry, this is an old term for on-air televisions. Its kinda the same image you get when your DirecTV signal gets scrambled during a thunderstorm.

We can check if the problem is on the hardware(projector) itself or if from source(device connected to projector) try to turn on projector without connecting any other devices to it. If you can still see the pink line- try to remove bulb and reinstall it. If all fails and pink line still visible, there is a problem with projector. If no line is present- check settings and change input signals.
Take out your projector's up cover. Take out your main board. Clean it up with air compressor. Place your board back to it's place. Make sure all the screws are tight... That should do it. Otherwise you need to change the main board...
This usually happens when some other appliance is causing noise on the AC power. Try powering the projector from an outlet by itself and whatever else you're running from a different outlet, preferrably one on a different circuit breaker if possible.
