pico projector hangs on splash screen

I acquired this from the surplus dept. But I found most of my questions answered online. except a major one.

When I power on the projector it just sits on the "dlp" splash screen.  I have found in other forum posts to let it sit on for 10 seconds before it searches for input. so I tried that with the beagle board.  Still nothing.  different cables... nothing. hooked the BB up to a computer monitor to make sure it boots, resolution is correct, and it is. then tried to hook it up to my mac (dont have a pc with DVi) nothing... as I think the Ver1 doesn't have EDID...

So I also found in this forum, Gavin had his hang this way too, so I'm wondering if the person that used this before left it in a different video mode and I need to flash it via I2C and set it to the normal video mode.  I have an arduino, and I have the ribbon to connect to it on the way from digikey...

Am I on the right track so far? or is this projector a dud?

any help would be greatly appreciated.

    Jake,

    Welcome to the DLP & MEMS E2E forum.

    So - this is a Pico Kit v1. Does it have an Auxiliary port on the side (covered with a rubber flap)?

    The splash screen should go away when the boot is complete. Have you tried sending I2C commands (via the HDMI port) from the BeagleBoard? If so, could you try to send the commands to put it in the internal pattern mode?

    Here is a snip from a comment I made a long time ago:

    The correct I2C address is 0x1b.

    The format is:

    bus3-i2c 0x1b wb4 0x04 0x00000001

    where:

    0x1b is the I2C address of the Pico Kit V2

    wb4 mean write 4 bytes

    0x04 is the register to write to

    0x00000001 is the data (32 bits - 8 hex digits) written to the register

    The command above should display a checkerboard pattern.

    Best regards,

    Pascal

    Thanks for the quick reply, I'm in the process of reinstalling the os on the SD card for the beagle board.  Once I get that complete (looks like I have some reading to do. I also found the 'projector tools') I will try this. Thanks again!
