Part Number: DLP6500FYE
I have purchased a DLP6500FYE few days ago, but when I set it on DLPLCR6500EVM to test the chip function, the DMD can't display the right pattern but stuck on a strange pattern as the DMD.jpg shows. Even when I powered off, the DMD still display this pattern. What's more, when I connect the DLPLCR6500EVM to my PC through a USB cabel, it can successfully connect but I can't choose 'System Controls' item to 'Normal' and choose 'Operating Mode' to 'Pattern On The Fly Mode' as the GUI.png shows. Looking forward your prompt reply.
I am sorry to hear about your issue. This appears to be a corrupted version of the out of box image set.
Please try reseating the DMD in the socket and carefully loosen and tighten down the flex cable. On the flex cable, please alternate from side to side turning 1/4 turn at a time on each side. Let me know if this improves or changes the behavior.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Fizix:
Thanks a lot for your reply. I did what you said just now but nothing changed. The DMD chip also stuck on a pattern whether powered or not as the figure shows.
I wonder if the DMD was damaged and is there anything I can do to sovle this problem or avoid this problem. Because this is the third time our DMD has this situation.
In reply to Wenbin Jiao:
Was the DMD left in this pattern for a long period of time? Since you say that you purchased it only a short time ago, I would contact the vendor you purchased this from and initiate a return. This is NOT expected behavior and appears that something is damage.
It sounds like you cannot select "Normal Mode" and cannot therefore test Pattern On-the-Fly Mode. Is this correct?
The DMD always left in the pattern for a long period of time. When I select "Normal Mode", then it would change to "Standby Mode" automatically.
I purchased this DMD chip on July 6th from Digi-key(Asia), a TI authorized distributor, and received this chip on July 16, and the Distributor Tracking# / SCAR# number is 74712563. Thank you for your help.
You will have to contact DigiKey to request a replacement.
We are sorry fot the difficulty with the EVM that you have experienced.
Hello again Winben,
Before you send this unit back, could you please try reloading the default OOB firmware that is in the DLPR900 folder for the 6500. If you do not have it, it can be downloaded from ti.com here:
I have updated the firmware before but nothing changed. I contacted DigiKey to request a replacement, however, they said I should send a request to TI and if TI approve of this request they will cooperate with TI to complete this replacement. I submitted a request on July 27, but nobody respond to me.Rroduct return-summary-CPR201042492.pdf
Have you heard back from TI on the request?
