Good day.
I have raised the issue many times on facebook but nobody seems to know exactly if it is possible.
My SKR SE BX board has gived me the magic smoke during printing. I was using the board in a voron-like printer alongside a second MCU for controlling Z steppers. I purchased the Manta M8P with plans on using it instead of the SKR and second MCU. I want to reuse the BX screen with the new Manta board through HDMI.
Luke managed to make it work by providing 5V to the board via ground and a Mosfet plus shorting out 2 pins on the LCD connector.
Unfortunately Luke is using an older version of the BX screen board and on the newer V2.2 boards, that mosfet is missing and the mod doesn not work even after discovering a way to power on the board. Shorting pin 1 and 14 does nothing( as per Luke's mod)
The issue:
When giving 5V to pin 1 and gnd to pin 2 on the LCD connector, the screen backlight and backside LEDS turn on but there is no image displayed on the screen. When using the wheel/selector( marlin/pi/legacy) it does nothing.
The HDMI board on the back of the screen has the HDMI Chip needed to display an image from a source and it looks like all the power connections are there so that means that the SKR BX SE board just gives video signal to the screen. There has to be an enable pin that enables the screen and its functions.
Please Bigtreetech, help me not create e-waste so i can recycle the screen with one of your shiny new boards :) And also you are a company that enables tinkerers , ENABLE ME :D or my screen at least :)
