I have been looking for discrets for the Panasonic projector PT-AE900U for some time. I tried pasting the two above for a custom code as usual. Unfortunately, they did not work. When verifying the code it appeared to have changed in the Proto edit software. When experimenting I noticed that after pasting the code it was OK but when clicking OK to save it changed. This seems odd. Does anybody know why this would be and how to remedy?
