Hello,
i have a Odyssey Neo G9, which is defective since quite some time. It does not turn on at all. The power LED blinks every 10sec or so very shortly.
I recently began to repair it. I have fixed one component on the mainboard, but sadly it does not seem to be the only broken component. I have circled the swapped component in the Picture. It was causing a short between 20V and GND. That short is now not present anymore.

However, the next problem is, that the "VDRV" Voltages are not supplied. The power supply defines them as 14.2V. When the mainboard is not connected, i measure 13V. When the mainboard is connected, i measure 0V. However, the pin for "BL On" measures 6V without mainboard, 0V with mainboard. I think this means the mainboard does not give the signal to turn on to the PSU, but ill gladly accept any other explanations for the behavior.
The "VDRV" pins are directly connected to the "VLED" pads near the backlight ribbon cables on the right side of the board. As implied, the backlight power is supplied through the same connector that supplies everything else to the mainboard and i can not test the backlight separate from the mainboard. This is most likely due to the mini LED technology used.
The Joystick for turning the monitor on is working as intended, and all signals get to the board, measured in the bottom left.
This leaves me clueless why the monitor wont turn on and i would appreciate any nudge in the right direction, or any direction for that matter.
Sadly i don't have an Oscilloscope and currently don't have the money to buy one.
Could i have broken something, causing this, by replacing the circled part?
Thank you for any help,
