Part Number: DLPDLCR2000EVM

Hi,

EVM is not connected to any host processor. When I give power supply, it turns on and shows flash screen, after 2 seconds the splash screen goes off but the D3 lights on.

How to trouble shoot? Due to this i could not connect with BBB.

Need some immediate help here.

  • Hello Gopinath,

    Is there any changes to EVM configuration? 

    Please check if "PROJ_ON_EXT" pin shorted or grounded in the connector?

    regards,

    Vivek

    Hi Vivek,

    There is no change in the EVM or EVM's EEPROM configuration. The standalone EVM is turning on, LED D2 followed by D3 and shows a splash image and goes off immediately. But the D3 LED is continuously lit up and ON. But there is no splash image is shown. 

    PROJ_ON_EXT pin (P2_15) is not fried or shorted, I have checked the U10 connection on the board. Please find the attached image.

    Gopinathan,

    Has the EVM always had this issue, or was it previously working fine before this issue occurred?

    Regards,

    It was working before. I bought just 2-3 weeks before from mouser.in

    Does it has warranty ?

  • In reply to GOPINATHAN M:

    Any trouble shooting steps, warranty details are highly appreciated. I don't think that we can fix this issue; I hope some issue on the main board itself.

    Even if this covers under warranty, shipping to and from will be additional cost.

    The main problem in India is custom and import duties, this is 60% more than the actual cost of the EVM when it comes to India. No warehouse in India is ready to ship. 

  • In reply to GOPINATHAN M:

    For warranty and product support inquiry you should check with the support hotline I've linked above. This is a separate channel than E2E.

    I hope this helps.

  • In reply to Philippe Dollo:

    Can you please confirm this is eligible for claim warranty. If this is a defect and needs to be replaced then I will contact mouser.in online store for replacement.

    Since TI customer support team recommended to contact mouser for checking warranty and replacement policy.

  • In reply to GOPINATHAN M:

    Is there anyway this can be fixed? If not, please confirm this needs to be replaced, I will ask mouser for replacement.

    When I contact TI help desk they asked me to check with mouser with TI forum reply for replacement request.

    Need your confirmation on the same.

  • In reply to Philippe Dollo:

    Hi,

    TI support team asked me to contact mouser.in for replacement.

    When I contact mouser.in they are asking E2E forum reply confirmation for this item to be replaced?

    Please confirm whether this is eligible for replacement of not?

    I was asking this question for a long time but no reply from your side.

    Appreciate your answer.

  • In reply to GOPINATHAN M:

    Gopinathan,

    Apologies for the delay. I am recommending that you get a replacement unit. Sorry for the inconvenience.

    Regards,

    Philippe Dollo
