Why not if it actually cures the glue that's turning yellow? That's what the UV light is doing. I mentioned in the other thread, anyone that has this problem can try it out themselves. Just get something like this: https://www.amazon.com/uvBeast-NEW-MIDI-VERSION-Flashlight/dp/B07D6D91FC Put the glasses on (UV light exposure causes cataracts).. and expose your yellowing MCU sections to the UV light for, say one minute or so, and see if the yellowing goes away or diminishes. Can't do any harm. Worst case it does nothing, best case the yellowing goes away. YMMV, IANAL, use at your own risk. But if my screen was yellowing, I'd try this for sure (I already have a bright UV light).
