Other Parts Discussed in Thread: DLP650LNIR, DLPLCRC410EVM
I am working with DLP650LNIR dmd, utilizing the DLPLCRC410EVM dmd controller evaluation module. Upon following the the instructions in the user guide for setting up the evaluation module, I was able to get the dmd board projecting the test patterns. However, there is a horizontal stripe that appears in addition to the displayed pattern (see picture). This bar will go away (along with the rest of the pattern) whenever I press the float all mirrors switch (SW3). But other than when that button is actively held down it always appears. I have attached a picture of this bar showing up when a test pattern is displayed, it stretches all the way from one edge of the dmd to the other.
For software control I am using the DLPC104 - DLP Discovery 4100 Explorer GUI v. 01.00.00.0A
I initially suspected that the flex cable was defective or was not properly connected, so I replaced it with a new one but the issue still persists.
Any advice for further troubleshooting steps would be greatly appreciated.
