Hi William,
Fluid intrusion can be very problematic and lead to highly erratic
behavior, if not a complete shutdown.
If an IC was internally damaged by moisture allowing for an undesirable
current path, then a chipset may
solve the issue. It may be a challenge to clean sufficiently unless you
remove (unsolder) the DIP sockets (big job).
However, if other components were damaged, it may require a complete
control board replacement.
We still have them available, if you want pricing, email me off list.

[RE-wrenches] Mouse pee in the SW
Sent by:

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
