My company bought 5 sets of DLP3039-Q1 EVM and received them about 1 week ago.
But there is 1 set that DMD cannot show test pattern via DLPC120 program control & cannot read/set RGB LED PWM value.
Even HDMI in video was identical condition.
I think this PCBA may have some problem. I would like to replace this EVM set.
My company returns the failed EVM and TI resends 1 new EVM to my company.
Hello Allen,
Welcome to the E2E forums and we hope to assist you with your questions.
Sorry to hear that you are having difficulty with one of the EVMs. Before you initiate a return, can we try debugging the issue?
With the one problem EVM, are you able to connect with the DLPC120 Automotive Control Program and see the system information such as the below picture?
Do you see any errors in this window?
When you attempt to show a test pattern or read/set the RGB LED PWM values, do you get any errors at the bottom of your DLPC120 Automotive Control Program such as shown in the following picture:
Can you confirm all wiring and cables are firmly connected and also ensure the DMD is firmly connected to the socket. Sometimes I have seen the DMD not be fully seated onto the socket which causes connection issues and no display out of the system.
Regards,
Alex Chan
