I found an article recently about bad capacitors in the VP6 (by Jackcon).
I honestly don't know if the same manufacturer produced bad caps for the
BP6, but the BP6 definitely has caps made by Jackcon. My old BP6 board
blew (*pop*) one such cap and the others have similar physical properties
as the faulty ones reported in the VP6. Look for bulging cap tops and/or
brownish ooze on top. You should pay particular attention to both
(1000uF/10v) 2x2 cap blocks: EC{20,21,24,25} and EC{18,19,22,23}.
I'll be fixing my BP6 board with new caps in the above locations as well
as the reported EC10 cap problem. As far as I know, simply replacing
the 1000uF/10v caps with non-Jackcon ones is sufficient. As per reports,
I'll replace EC10 with a 1500uF/6.3v cap. I'll send out another note once
my changes are complete (reporting success/failure).
Regarding the VP6 cap problem, some people have replaced their own caps
with caps of the same uF/v rating. Others, who have gone the RMA route
with the VP6, had their caps replaced with altogether different ones,
although I can't recall the uF/v rating on the new caps.
