ICP Self Test failed

If you get a ICP Self Test failed error message on the Christe projector, it can sometimes have no impact on performance and sometimes you can get very strange colors. Best way to check is to play content or put on a test pattern. Restarting the projector will often clear the error. If you get picture issues, you can check engineering logs to see where the issue is:

To resolve, follow the steps outlined below.

1. Reseat the following: ICP, LEQD and light engine cables between LEQD and the light engine.
2. If the issue continues, swap the color that fails with a working color on the LEQD board side.
   1. If the issue stays the same then the issue is either: red light engine cable or the the red light engine formatter board. You can try to swap the entire red cable with the green cable. If the failure follows the cable then replace the cable, if it doesn't follow then the light engine should be replaced.
   2. If the issue changes to another color then the issue is either LEQD, backplane or ICP board. You need to swap components between projectors to see if the error stays or follows the part. When you find the part with issue, replace with spare and contact Christie for a warranty replacement.
