DLP4710: FQL OR AFQL FOR VIVITEK QUMI Q8

Part Number: DLP4710

Hello,

I have a projector Vivitek Qumi Q8 and I need to replace the DMD CHIP because it is broken. 

I live in Brazil, so Vivitek does not offer techinical assistance here. I took my projector to another techinical assistance and I was told It is needed a new chip DMD DLP4710FQL.

But I only find DLP4710AFQL and I read that this chip would need a new firmware.

Is it possible to my assistance update to a new firmware if I buy this one (DLP4710AFQL)?

How can I do it? Where can I seek support in this case?

  • Hello,

    Welcome to TI E2E forums and thanks for showing interest in the DLP Technology.

    Can you please let us know the DLP chipset (Controller, DLPA) that your projector is based on, so that we can share the corresponding firmware.

    Regards,

    Mayank 

  • Hello,

    thank you for replying.

    How can I get those informations? I know there is a reference number registered in the chip: DLP4710FQL.

    Some others specifcs in manual guide: Single Chip DLP Techinology by Texas Instruments, 0.47'' DMD (Chip Seize), max. resolution: 1080p @60Hz.

    Inside the projector menu I could access these information about Firmware. It says "Firmware: 14".

  • Hello,

    I am sorry that you are facing problem with the projector. I want to reconfirm that DLP4710AFQL DMD will require firmware upgrade. Unfortunately, this firmware has to come from manufacture. The DLP4710FQL DMD has been end of life.

    Manufacturers do several  hardware related and firmware customization for a product. TI does not have a access to such information.  You may want to contact their corporate or South America office and request for firmware.

    Just to give you a perspective of customization -

    for hardware typically: combination for chipset, DMD pin out configuration , I2C address.

    For firmware - LED current, duty cycle, and image related optimization.

    I am sorry we are able to assist you in this matter.

    regards,

    Vivek

  • Thank you,

    Vivitekcorp doesn't respond me, and I don't think there is a south america office.

    I saw there is some chips DLP4710FQL being sold at AliExpress and eBay. Do you know if they are reliable?

    In any case, thank you again.

  • Hi,

    DLP4710FQL on Aliexpress- It is very likely that those are aftermarket and unauthorized source. I am not in positon to make any comment.

    Regards,
