Kevin,
Is your customer designing their own board (especially thier own flex cable)?
We were never able to determine the root cause, but the customer was designing their own board and DMD board and apparently had not correctly connected the signals.

Hi Fizix,
Many thanks for your reply.
Yes, My customer designed their own board. But they didn't use flex cable but a connection finger.
And their connection is as below:
DLPC900 DLP6500FYE
DDA_P[15:0] D_BP[0:15]
DDA_N[15:0] D_BN[0:15]
DCKA_P DCLK_BP
DCKA_N DCLK_BN
SCA_P SCTRL_BP
SCA_N SCTRL_BN
DDB_P[15:0] D_AP[0:15]
DDB_N[15:0] D_AN[0:15]
DCKB_P DCLK_AP
DCKB_N DCLK_AN
SCB_P SCTRL_AP
SCB_N SCTRL_AN
I also let customer do the DMD bus swap of the firmware. But it didn't work. It is same in Pre-srored Pattern Mode and Internal test pattern.
Do you need the schematic?
Best regards,
Kevin
