PH test it, if you can. If it's caustic, then I'd suspect condensate mixed with electrolytic capacitor gunk. If it's acidic, I'd suspect either an industrial cleaner or again condensate that had mixed with acid from solder flux, then partially evaporated, leaving a concentrated acid ready to burn you. That's my cockamamie theory. If it tests acidic, put on some gloves and eye protection and pull the boards out you can, leaving just the (discharged) tube and the case. Then flush everything with a mix of water and baking soda. If it's caustic, clean it out with vinegar (ie.. 3% diluted acetic acid). Then flush the whole thing with purified water, clean the boards, and reassemble it. It might be a lost cause if that stuff has got down into the flyback transformer or ate all the solder mask off your logic board. -Swift
