It lights up fine, then after approx 2 minutes, colors will start flckering, the lamp turns off and the fan is very noisy. Every time the same way

Here's a link to a 15 second video showing it happening (you'll see the colors flickering after 5 secs:

Can anyone help tell me what it might be?

Happy to buy a bulb but not sure if that's the issue?

Thanks!

    The same problem just appeared on my projector. Where you or (anyone else) able to fix it?

    I could finally fix my problem by cleaning the sensors of the color wheel. For doing this procedure there is no special knowledge of electronics needed, but it can still be a bit tricky to disassemble the projector until you can reach the sensor (and there is of course always the danger of destroying something)
    The following links helped me a lot:

    (the 7550BD is nearly identical on the inside. Fortunately I was able to losen the screws on the side of the color wheel without the necessity to dismount the circuit board. Some patience was needed, though)
