820-01041 U9850 problems

Hi

Can any confirm if the U9850 on the above board has firmware. I have 2 identical board here with the same problem no internal image/backlight and I purchased from AliExpress 5 x CBTL06142EEE and it still not working. I've read mix posts on different forums about it having firmware.

Thanks

For older models, Analog Mux is not firmware dependant.
I cannot confirm that for T2 platforms, but seems to be the same chip.
Be aware with chinese "new" chips; could be refurbished, sanded/polished and remarked, look like new.
