Part Number: DLPLCR6500EVM
Hello,
I started working with a DLP LightCrafter 6500 module in both video and pattern mode but since yesterday it does not work anymore.
Board: USB connection works, the heartbeat LED is blinking but it remains in standby mode and I get the error message "Invalid Controller/DMD" when I try to switch modes and the status "Controller/DMD incompatible" is ticked. (Image 1)
DMD: The overall pattern on the mirror is a very faint echo of the last pattern I used, but one side of the mirror seems to be in more or less random orientation and the other side is ordered. (Image 2) As a side note, while it was still working I had the impression that the mirror was quite hot to the touch, is that normal? Should it be actively cooled?
I tried:
1. Remove power and restart after a while
2. Resetting via software
3. Release and reinsert DMD as described in this forum article (https://e2e.ti.com/support/dlp/f/94/p/616210/2296999?tisearch=e2e-sitesearch&keymatch=dlplcr6500evm#2296999
I can exclude:
1. mechanical damage to the board (the DMD was in a holder) and after it stopped working I checked for damaged electronic components
2. Damage to the flex cable, the bend radius has definitely not been lower than 5cm
I there anything I can try additionally?
I would appreciate any help how to solve this issue, thanks.
Klaus
