Hello everyone.,

I am heartbroken over the sudden death of my LG 34GK950F Monitor. I've had it for only about 5 years, and yesterday, it suddenly started to make a buzzing noise, as thin white horizontal scanlines appeared across the screen, before the image faded away to black.

I bought the screen shortly after it came out, but now that some years have gone by, it seems to be a pretty well-documented failure mode, as can be seen in the linked page above. It seems a thermal issue is leading to ribbon cables melting.

I have spoken with repair shops and they've said the monitor is too old to have replacement parts available from LG, so I'm going to try and repair it myself. I'm fairly experienced with electronics and soldering work, though I've never tackled something with as many connectors as a ribbon cable.

My question isn't about how to do the repair, but rather, how does one spec out and purchase a replacement ribbon cable? I don't even know what type of connector I'm looking at, or how the nomenclature works for ribbon cables.

Any help is appreciated. If I can't find a replacement ribbon cable, my next approach will be to buy a broken monitor on Ebay and do a Motherboard cable swap, or just use the cable from that screen.

I will also find a way to increase the cooling through the chassis so this problem doesn't happen again.

Thank you.
