I completely dried a display that had water across the screen. Picture of the drying machine further up the posts. Not a trace of water and now fully epoxied. Worked great.
That image is not water in the screen, it’s epoxy. Whole display module is filled with epoxy, the image shows the epoxy not properly wetting out but it’s fully sealed all around. I’m confident no water will ever get in. Yep we have experience every single display eventually failing as well, so disappointing. Hopefully this simple epoxy fill fixes them.

After replacing the LED, the remote control started working. Before that, there was a black screen!
I gave the remote control to my friend for repair. He is an electronics engineer and he has the equipment. He disassembled the screen with a stationery knife, but very carefully. And I soldered the LEDs with a hair dryer.
