Hisense 55Q9G Android reset / factory firmware reload

[mon2]

Please see attached. Found this in a YT video. Is this the PWM frequency to change? I recall Hisense tech mentioning 180 zones - perhaps change this value to a lower value?
( not sure if we have this same menu but will ask the client later today )

this what did you show also there over load at BL the value should be not more as ---- Min BL 0... 20BL 30 .... Mid BL 80 , 80BL 90, Max BL 100 .... so at user setting menu set BL level to ... 35 -40
PWM Freq are one of BL zone... but it related to Factory Factory Option which key and version didn't show at yours photo

At this time, I finally have the latest firmware for this 55Q9G and also the 65" version of this model. Can this firmware be applied using a USB key to correct the parameters? Even though this TV with the 65" firmware has auto-updated to the latest - can we apply the 55" firmware? TBH - does the USB firmware tool even know the difference of the firmware packages? I think not as long as the pkg file is properly CRC'd.

Hi, would you mind sharing where you got the firmware. I'm having the exact same issue with a 55Q9G. I would like to try re-flashing too.

Thank you for the FW mon2. When I turn the TV on, it gets to the home screen, but after about 10 seconds the TV turns off. It's not enough time for me to start the FW install off the USB stick. I read that if you hold the power button on the remote when turning the TV on with the USB stick plugged in, it will auto install the FW. All I got was the "checking" window like it was checking the FW prior to install. When that completes the TV turns off and goes no further. Any thoughts on what could be happening? I'm stuck....

Hi, my guess is: set apart the replacement main board, take the original one to a service shop to do an emmc reballing, then try the update with the correct file.. if it works then wait, there's a further step.. bye..

Thank you David.p, I will see what options are around for recalling...
