Mine did exactly the same, electrolytic caps on the A9 (Power 
distribution) board are the most likely culprit, they need to be 
replaced with the best you can find (125°/Low ESR types)
you might as well do them all (5 if my memory serves me right) at once, 
if the aren't gone already they will go eventually)
