Thank you so much @ccain123 ! Yes, I did end up ordering a fairly new display from AliExpress, which arrived in a week. Thankfully, my display works exceptionally now! Paying a little over $100 seems way better than spending $1599 for the new studio display which has the same basic features, even though I hesitated myself at first also in fixing this “old” unit. I hope it lasts another decade, God-Willing! I highly recommend anyone else to also just fix the unit by replacing the LCD.

Hello All, this also has been happening to me where the monitor just flickers starting at 20% brightness. Anything lower seems to be fine, but it is too dim. So I just recently ordered a used/working logic board and replaced it on my unit. Unfortunately, it is still happening. I doubt it is the logic board, since it is happening on 2 different logic boards. Does anyone have any other suggestions on what it could be? Thanks so much.
