I HAVE just successfully adjusted the G2 pots on my Sony 1272Q. The ones that come from the factory with a paper sticker over them that says 'Don't touch the screen volumes'. The ones that are built so each one is enclosed by its own little plastic collar so that the unwary user won't jostle it by accident. The ones the consumer is never, ever supposed to touch.
Those G2 pots.
My pluge looks much better now, thanks.
Ph33r my 133t skillz!
