DLP2000: Device does not boot/display when power is applied

Matthew Berlin
Prodigy 40 points
Part Number: DLP2000
Unboxed device. Applied specified power directly and got a garbled splash screen (in red only) for approximately 3 minutes.
Gave up: unplugged, replugged ... and now no image is displayed (no projection at all), but the two green lights continue to blink.

    Matthew,

    You should start by verifying the following:

    > Reseat the LED flex cable on the EVM and ensure the connection is secure

    > Reseat the DMD flex cable on the EVM and ensure the connection is secure

    > Ensure you are not hooked up to the BeagleBone Black, in case there are any issues with your software configuration

    > Ensure you are using a 5V-3A DC Power supply (such as the one recommended in the EVM user's guide)

    If your device is working OK, you should see the splash screen upon connecting power. If you can confirm that your connections are all secure and the system still fails, you may be encountering a hardware failure of some kind. In this case I'd recommend you contact TI store support to request a warranty replacement unit.

    Let me know if you have further questions.

    Regards,

    Philippe Dollo

    Philippe,

    I have verified the following:

    * Re-seated both cables
    * Confirmed device is unattached from other devices
    * Double checked power supply with multi-meter, confined a 5V-3A DC

    Still only seeing the two green blinking lights and no projection.

    I have already contacted support, and will need authorization for a warranty replacement.

    Thank you for your assistance in this matter,

    - Matt

    I'm not sure what I was doing wrong initially, but after one more reseating, everything is working as it should.

    Thanks for your help.
