DLP471TEEVM: DMD Error (DMD not working)

You may try and check the connectivity of the lines from the controller board to the DMD board. Also try to make sure the two are firmly connected

Thank you for the reply and suggestion! I have checked the connecting cables for continuity and they both work. The two of them are pretty firmly connected - the pins have not been worn out and they are stable. Additionally, I think I would not have been able to read the voltages at the test points of the DMD board, have those cables been the problem. Does anything else come to mind? Thanks again!

Have you tied swapping out DMDs?

This is a great idea, but unfortunately, we have only this one :/ ...

Hello Dimitar,

We're looking into this issue on our end and will get back to you within the next few days. Thank you for your patience.

Best,

Please try looking at the serial output from J102 using USB to serial converter

Hello,

sorry for the delayed reply but we had to wait for a USB to serial converter cable.
I used Wireshark to detect some of the information exchanged between the devices over the Serial J102 port:

To me, it looks like some configuration data is being sent. I have attached the captured package file here:

https://drive.google.com/file/d/1DFmBmDQZjeqVvtYuhilHAhMqyax2Gj50/view?usp=sharing

Looking forward to your reply!

Just requested access to those files

You need to open a COM port in a serial terminal, which should populate when you plug in the USB-Serial.

I use Teraterm: https://ttssh2.osdn.jp/index.html.en for the serial terminal

Hello again! Okay, I will do that and report back asap. Thank you!

So the Serial J102 using TeraTerm just displays the commands that I send. Here is a snapshot from one session:

And another session which I presume shows the errors (maybe DMD Power problem?):

Looking forward to your reply!

I'm a bit suspicious of this: "illumination: DMD LSIF comm error in DMD_Power()",

which makes me believe there is a broken line or pin on the Low speed interface. Can you check these lines in particular to make sure the signals are getting through?

Hello once again. I used a Tektronix TBS2000 Series Digital Oscilloscope (70 MHz, 1GS/s) for the measurement (it is the only one we have). I am not sure if it can measure these signals at all or if I am measuring them wrongly. I definitely see some mV jumps (~150 to 200) from almost all the pins/lines you mentioned (LS_CLK_P - pin R9, LS_CLK_N - pin R10, LS_WDATA_P - pin T10, LS_WDATA_N - pin T11) besides LS_RDATA_A_BIST_A - pin T13. T13 is physically not on the back where I measured the others. Here are some pictures of the measurements and the DMD pins, as well as the missing T13 on the back. The blue cable connects to the GND of the board.

Unfortunately, I am not sure it is easily fixable.
We are doing research and our project has been on hold now for 14+ days.
Our supplier (DigiKey) has been following this troubleshooting session and told us that to call the warranty into action we have to reach some sort of conclusion. Do you think this case qualifies for a replacement and is there anything else we can do to try to fix this one that does not take longer than 1-2 days because we can not afford to lose more time?
Looking forward to Your reply and thanks for the kind help so far!
