When i turn my projector sometimes the picture is there and after a minute or two it will either turn into green lines or red or just a blue screen. essentially no picture just wierd digital multicolor effect)
Hi and welcome to FixYa,
Offhand, if the easy checks/repair, cables, connection, calibration, source change would not address the issue, then it would be a component/board failure.
Initially, the blue screen is video mute, no recognizable video signal detected, whereas "green lines or red" are as best described as random video noise. Both indicate a problem at the digital video processing board. This would be especially so if you are using digital input HDMI (HDCP).
This of course would require opening the unit, perform voltage measurements, determine faulty component and subsequent part(s) replacement. Further, a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron would be required. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.
Good luck and Thank you for using FixYa.
I happens sometime because of Driver too before installing latest driver test your Project with another Laptop and if it does same then you have problem with your projector and if not then with Laptop.
and if you find problem with projector your first action will be replacement of Lamp and if you find bug with Laptop then disable all VGA drivers and install latest ones.
and if you get same bug even replacing driver then you have problem with your VGA out put port.
please post back if anything changes.
I think u need to replace the lamp

Check if the screen or the lines change when you move the cable that connects to the computer. It could just be a bad cable or the connection could be loose.
If you haven't tried yet, do a hard reset. Disconnect the power cable and press the power button on the projector for 10 seconds.
Aren't you getting the same lines on the computer's monitor or if you're using a laptop, the LCD screen?
