Part Number: DLP3000-C300REF

Dear TI,

I've got one DLP3000 (out of six DLPs on a rig), which gets stuck in the booting sequence.

When I boot from NAND, the DLP stuck at 98% during booting.

When I boot from SD card, sometimes it succeeded, sometimes all the LEDs on the control board (top PCB) are OFF at 98%.

Does that mean the NAND is broken? How can I test/fix it?

Or is there a way to reliably boot from the SD card?

Thanks.

Best,

Joseph Huang
