I have numerous Creston TPS-2000L touchpanel home automation devices, which incorporate a Sharp LQ5AW136R panel. They all exhibit the same fault. They are about 10-15 years old.
The fault can be seen in the attached photo. Basically the displays are all washed out, to be point of being unreadable.
Clearly it's an issue with the panel. But my question is whether it's just aging related (e.g. all the pixels in the LCD wearing out) or whether it could actually be a more specific component (i.e. one capable of being individually replaced). I've seen suggestions on other similar faults (though not on this panel) that e.g. the gamma correction IC could be the issue. See e.g. here
New panels are available, but they would need shipping from abroad and are quite expensive. The Crestron device itself is EOL. If it's likely to be an individual IC, I'd much rather just replace that.
Any help appreciated - thank you.
