DLP4500: EVM Board Hum

Part Number: DLP4500

All, I am powering on the EVM using the recommended charger and experiencing extremely loud humming, I've eliminated the fan as the source, but am worried something is wrong with my board. Could anyone confirm if this is normal? I've attached an audio clip (apologies for the poor quality).

  • Hi Hunter, 

    Welcome to TI E2E Forums and thanks for your interest in TI DLP Technology.

    Some amount of inductor hum on the board is expected and is normal behavior. Are you observing any problem in operation/brightness/display etc? 

    Thanks & Regards,
    Hirak.
