From the pics on the linked thread, I could see some 22uF 16v caps, is this correct and are they all same?



The electrolytic capacitors on the board are all 22µF, but the polarity of three of those capacitors as shown on the board silkscreen is incorrect.  This guide shows how to replace the capacitors with the correct polarity.

I have other information on the A3640 including the upgrade to hardware revision 3.2, listed here.  Essentially it involves replacing U209.  I stock these programmed parts which are available here.
