Hello everybody,
I want to turn the backlight of my old LCD Acer Monitor (Model G236HL) into a light/lamp.
All the electronics still work. I can turn on the backlight with the mainboard. Even when the mainboard is only connected with the backlight LEDs and the power supply, and the logic board for the screen is not connected the light turns on.
However, it automatically turns off again after a few seconds.
I saw a youtube video (www.youtube.com/watch?v=Y2KK4YiOO1o) that explains how you can use the existing mainboard to power the light permanently. However I can not find any of the pins labeled as: "LED_EN (the 'on button') is sometimes called EN, ENA, BL_ON, LEDON, BL_EN, or ENAB PWM may also be PWM_1 VLED (12v) may also be called VCCS, or LED_VCCS. If you can't find it try and find the fuse instead and solder to that."
So, I am wondering now, if I also have to use the logic board that is responsible for the pixels of the screen?
And if it is even possible to achieve what I want with the mainboard?
Unfortunately I could not find any circuit information online. The only thing I could find is related to a similar mainboard, but not the same: https://www.manualslib.com/manual/455818/Acer-H236hl.html?page=54#manual
I appreciate any help, thank you.
Regards,
Lucas
(I have attached pictures of all electronics. The small cabel is connecting the mainboard with the LEDs, the broad cabel is connecting the mainboard with the board that manages the pixel screen.)
