The point, after all, is to get your lcd working, correct?

Jim Land,

Many times I try to learn from facts of life that cross my path, I
guess we all do; this is called evolution.

But you're right, this is not worth it; the point is that I was just
being too cautious to avoid buying a new tube just to discover that the
problem remains; after all, a new tube shall travel a long way from a
shop in the US to my country in Europe.

Thank you for your guidance, I'll do as you said.

Best regards
jss
