William,
I don't have a definitive answer, but I doubt it's either display
or chipset; more likely in the boards. The chips are EEPROMs that
contain programming for the firmware; unless there's a bad socket
connection from the pee, they won't be affected. The display is
pretty much self-contained within its plastic case, and not where
the corrosive pee is likely to end up. I'd more suspect circuit
board troubles, but I can't tell you which ones.

Friends:
I
had a mouse take up residency in an SW inverter (SW4024).
It peed on the top circuit board and chewed on one wire, at
least that we found. We have had this happen before and
solved the problem by cleaning and drying.
This
time the mouse pee was minimal and cleaned off easily and
what appeared to be throughly. However we can't get the
inverter to work reliably. Sometimes it works and sometimes
it does not. The overload light is solid and the error
light flashes. The controls work on some menus and not on
others. If I shut the inverter down it won't come back on.
I take off the cover, look around, connect and disconnect
ribon cables and it comes back on, only to go out a day
later.
I
have a spare display and chipset. I am considering changing
out one then the other.
Any
adivce would be appreciated.
As
always, I am very grateful to all of you. It seems I have
been receiving more advice than I have been giving lately so
I look forwards to the opportuntiy to reciprocate.
Sincerely,
William
Miller
