I found a link here that lets you download the service manual: http://elektrotanya.com/panasonic_dmc-gh3_series.pdf/download.html and I read through at page 16-19 shows you "How to define the Model Suffix", it shows you how to select the model suffix after replacing Main P.C.B.
My question is would it be possible for me to change my GH3PC (NTSC) camera to a GH3GC (PAL - India)? This would allow me to use in Europe without recording limit.
Nope, you can do this thing only once and only for new MB.
