I've been leaving my link box on all the time, why wouldn't you?
But I saw some people on the forum having problems when leaving it on.
I just returned from 3days away with it left on stby and not being used at all, to find 2 big purple blobs in my right lens.
I thought the panel must busted and was expecting I would have to return it, but after switching off the link box for a few hours its back to normal
Sorry pic is not the best, but was hard to get a clear pic
