My thunderbolt display has been flakey for the past few years with the backlight intermittently deciding to not come on.

I have previously been able to resolve this issue with numerous bouts of unplugging it and plugging it back in but it finally decided to not come back to life this week when I need it most for telework.

Based on advice in prior posts from @danj , I replaced the logic board to no avail. Upon teardown, I did notice the left bottom backlight connector is loose so wondering if replacing the LCD panel would be the next step? Would the whole screen not work if just one backlight connector is bad?

Of note, the display works (no backlight) and all accessories work fine.

Thanks in advance for any replies!
