Part Number: TSW14J56EVM

Hi Team

We purchased 3 PCS from TI Store, and the test found that 1 PCS had no output and could not be run. Please help to provide advice.

    User,

    Make sure the 5V supply for this board can source at least 4A. Are all of the power status LED's on? What is the status of the 8 status LED's D1-D8?

    Regards,

    JIm

    Hi Jim

    The supply voltage is 5V, and the LED status of D3HE and D4 is somewhat different from that of other products. Please refer to the test video of the normal board.

    User,

    It appears this one board may have a hard failure. If you bought this from a distributor, you will have to work with them to get a replacement. If you bought it from the TI Store, the following link has the details and a link to the form to start the return process.  Once you are on the returns and refunds page of the TI Store look for the hyperlink which says: TI store customer support form. 

    Regards,

    Jim

    When we applied for returning the product, we were told that we need to contact the engineer to confirm whether we need to return the product？Could you help me to confirm?

    User,

    Your unit is defective and needs to be replaced. We do not need the defective unit returned to TI.
