48G won't turn on, any suggestions? - lemontea - 05-23-2017 05:32 AM Everything looks good and clean outside. No corroded battery contacts. I checked batteries with a multimeter. All good. Tried pressing and twisting the unit a little, nothing works. Suggestions? Thanks.

It's amazing how many "dead" 48's can be turned on this way.

Last (very last) resort will be to... open it and see...

So you may search this forum using Google ad hoc searches, maybe you get useful hints. I'm sorry I don't have precise links.

Otherwise... will have to do the POP and SNAP... which I really want to avoid. |
