Title:

Dead Mac mini with no obvious damage

Text:

i received a mac mini with no signs of life.

there is no visual damage on the logicboard.

i removed the logic board and found some markings on the board.

testpoints at the following parts on the bottom side are marked "pink": U6400, U6410, U9500. those areas/parts are marked "blue": the circuits between R9537/C9522 and C9525/R9540, the printed text of L4732/R4732/R4733.

on the top side is only one "red" marking on C9521.

i've read a few things of other dying minis, some suffered the "failing fan issue" - but i don't think that those things are related. others died during the setup/update of 10.6.3.

the pram battery had 2.99v - but nothing changed after replacing it with a new battery.

and please - no "get a new mini" or "replace the logic board" answers.

i want to know if those computers are fixable or not - there are way to much minis out there that could do a great job in those times (mine is a 2ghz c2d with 2gb ram - not a "crappy" old 1.5 core solo)

the cpu isn't the problem, tired it with different ones, the brick works too - tested on another mini and it delivers around 18.5v to the board

any useful suggestions??
