Here you have some pictures of three different units with same problem. But you can have a hint if there is some gold-colored spots. I mean, it is the one which is all metal so leak happens just in the opposite side. The problem is that the battery side you see is the good one. Problems caused by this are mostly related to the display, from a completely dark one to a semi-working one, but you can get all kind of weird problems, as data and control lines from the main CPU pass just below the battery. And, in all cases, battery voltage was fine, but it had leaked. Four units I have fixed, included my own one, had related problems. This is the more recurrent problem I have found so far. There are some typical ones you can find so I will document them here. This page is dedicated to the Kenwood TS-790 VHF/UHF/SHF all-mode transceiver problems.
