We all assumed that the glue is leaking into the screen. what if that yellowing is not from there? I am told there are multiple issues including one that could be fixed through software. the reason sis that the glue is not the problem. the light diffuser of the LCD is the problem. Those are used to diffract light from the LEDs uniformly into the screen. There are several vendors of those diffusers which are usually in the form of a sheet of poly-carbonate (or similar) that has a chemical layer of highly difracting material. Those can develop the yellow color for various reasons. Some UV light applied to this substrate can fix the issue apparently. There is material on internet about this. Again, this is my theory after digging into the light difusing techniques in the LCD\LED pannels. The reason we don't have an ETA is because they know a tone of cars will need to be fixed and they need to plan it after serious testing including fixing and waiting to see if it will re-develop the yellow. I was glad to learn yesterday that they are not just giving us bull$$t but they are working on it and it is for real. Now.. there is no reason to go blast me about this theory - just go the SC and ask.
