All the ICs (I think there are 4 on the 2S board) are encased in something
like epoxy, proprietary, made for Olympus by Sharp and other suppliers.
It's too much too get involved with. Cheaper to buy another used camera.

| As the owner of a 2Sp, this statement kind of hurts... But as an EE
student
| it also leads me to ask the question on what is on these circuits that
burns
| out.
|
| Are these proprietary semiconductors that can't be found, scrounged, or
| ordered? I'd assume they're surface mount devices from the size
| constraints. Even then, is it one of these irreplaceable components that
| bites the dust or is it something else in the chain?
|
| Anyone have a photo of the board? A schematic of this mystical circuit?
A
| dead board to study?
|
| I may be biting off more than I can chew by saying this, but what
| technically is stopping me from putting this circuit into my CAD software,
| routing some boards, and spending a month or two studying this thing
between
| classes? I've got lots of non-photographic toys to play with here at
| school...
|
| Just thinking. Sometimes it gets me in trouble :)
|

|
| PS - My 2Sp is in John H's hands at the moment... Hopefully its just an
oily
| magnet or something, otherwise I might just get that dead board sent back
to
| me in a few weeks :( The wait is the worst part!
