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

Trust me on this. There is no quick fix.

Backlight leds will need to be replaced. All of them will fail one by one.

Been there , done that.

Monitor is sitting in storage room with my fist shaking over Gigabyte head for the failure.

And its not cable issue. Led light in a led strip dies and entire led strip stops working as a result. (Cable might have been overheating , but that is not the cause of the failure. Overcurrent is. Cable was overheating due to power issue and led fails to survive that much current after some time.

All of them will fail eventually if u push using the monitor. I have entire two rows of leds dead.

RMA only possible if i send to Poland (closest center to my country) and it costs 250euro via train. Its abomination to even offer that. And without any assurance that they would even fix it if its being sent to them!

There is no one even remotely capable to deal with backlight replacements in my entire country and i contacted them all !

They either are not qualified, incompetent or simply do not wish to be bothered , because disassembling alone due to fragile plastics in gigabyte product makes it alone a nightmare

@icelancersr ever given it any thought of replacing the backlight strips yourself?

@oldturkey03 With what? My nuckles shine in the dark but then i would be without them.

Those led strips are quite unique design and power.

Unfortunately i left my replicator with my ex

On top of that , unqualified opening resulted in many broken screens as you can see on youtube. Even guy who posted "supposed fix" broke his own monitor by attempting to do his "quality fix" as u suggested

Also "fixing" it by removing bad led from strip is just very bad. Those strips couldnt handle the current while strip was full and let alone with less resist while leds missing. And for that either i am not qualified electrician to understand how much power is proper power.

Parts are impossible to buy as they dont exist anywhere. STRIP LB32123 V3 00 R, LB32123 V3 00 L

@icelancersr I've repalced quiote a few an learnd from my mistakes. Yes, I have broken to screens myself but learned that this is always related to overflexing the LCD screens. We just do not realize how thin and fragile they are. You do not have to be a qualified electrician to replace those, you just have to have patience and a few good hand tools. It is not as complicated as it sounds. Youtube is a good tool to get ideas, but it can't tech you how to do the actual work. That can only be accomplished by physically doing it. Not sure where you are located about looking for parts. Those are aroind just not in abundance. There are always ways in fitting other LED strips to make the monitor functioning again. Right now, the monitor does not work. So, no matter what, it can only go two ways. Either you get a working monitor back, or you continue to have a broken monitor. The is no change from what you have now.
