DLP4500: Blank vertical lines

Part Number: DLP4500
Other Parts Discussed in Thread: DLPC350

Hi Experts,

We're experiencing blank vertical lines as seen below. If we run the invert pattern (on something else than the TI test image) we get a totally inverted illumination. Any idea what can cause this? We're running it on a custom made board with the DLPC350 that has a design very similar to the Lightcrafter design. All power rails go up and down in the required sequence. Signal quality looks good at the DMD end.
