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. eric.bent...@schneider-electric.com Rgds,

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 ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service. ______________________________________________________________________ _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
