Part Number: DLPDLCR3310EVM

I just received the product last Wednesday. I used the power source recommended for this model(19V).The power source was connected to the DLP, after this was working without problem for 3 or 4 minutes, then switch it ON, it reflected the predeterminate image for a few seconds then the DLP3000 PMIC and LED Driver sparked, follow by a noise and then smoke came out. From this moment stop working. I would like to know what happened wether the product was brand new and I used the correct power source. 

Thanks

  • Hello Manuel,

    I'm sorry to hear about that. This EVM does use a 19V, center-positive supply. Can you send me a link of the exact supply you used? Is there any visible damage on the board? If so could you upload a picture of it?

    Thanks,
    Kyle

    Hi Kyle, I hope you are ok.

    I will attached pictures of the power source that used and of the board also. There is not any visible damage in the board or in the product, just stop working.

    Looking forward to hear from you

    Regards

    Manuel

    Hello Manuel,

    That power supply looks like it should work to me. I would have told you to make sure it's the correct polarity; however, an image would not have come up at all if the polarity was incorrect. The only other thing I can request that you check is to use a multimeter and verify the power supply is actually 19V . You didn't make any other changes to the EVM before powering up did you?

    If you can verify the above two points I think I will have you contact the distributor to initiate a return so we can determine the root cause.

    Thanks,
    Kyle

    Hi Kyle, thanks for your answer.

    Actually what you suggested was the previous step that I did before plug it. I took a tester to check the power because I know that sometimes says that has a power and then have something different. The power was what it says 19V.

    Regarding the second point, no I didn’t do any changes before powering up, just took from the box, tested the power source, plugged it and that’s it.

    I will be waiting for your answer

    Regards

    Hello Manuel,

    Unfortunately I cannot think of any other debugging steps. Are you able to contact the distributor where you purchased the EVM from to initiate a return. Hopefully they can get you a new working unit and we can investigate this issue when we get the board back.

    Thanks,
    Kyle
