I have a Roaming Partial LED Backlight outage on my Gigabyte G32QC

I have a Gigabyte G32QC monitor that experiences a partial backlight outage on a section of the monitor. The section of the LED that goes out depends on the day. The issue can sometimes be temporarily resolved by power cycling the Monitor or disconnecting the HDMI or Display Port cable. ( I tried Multiple HDMI and Display Port Cables)

To describe the roaming divide the 32 inch monitor into 4 equal Vertical sectors.

(|1 |2 |3 |4 |) The issue began on section 4, move to 3, and currently in section 2.

(I do have images of when it was in section 3 and now section 4).

I did contact Gigabyte Technical Support who informed me to update the Firmware via OSB sidekick from F09 to F011. This did not resolve the issue.

There is one video that claims the ribbon cables are at fault, which to mean does not make sense as the issue is resolved with a power cycle or removing the display cable from both the PC and Display.

Happy to provide any additional information! IDK if I can repair this monitor as it appears Gigabyte is not keen to provide parts or schematics.

@thomaso77906 this could be a backlight issue. Since your monitor still comes on try this. Decrease your backlight to a bare minimum lets say 1/2 of what you normally work with. Check your menu and see if you have some sort of warmth/different modes for the display that you can decrease as well. Then try to turn it on and see if that made a difference.

Check some of the forums and reviews and you will find out that there are dimming issues with theis series monitor. Seems like a firmware update can resolve this. Check this video for the firmware issues.

If none of the software or menu issus resolves this, then it is possible that you are having backlight issues. Yes, there is always a possibility that it is your backlight inverter circuit as well. For that, you would need to measure the output voltages to your backlight and see what you get on that and if you have that voltage consistent.

While you are at it, check your ribbon cables as well to rule out any damage on those. To disassemble your monitor and check the board as well as the back lights use this video
