This is a common problem, the hyper board has bad caps on it. The hyper
boards on the *H81 version of the Toshiba have about 16 caps that Toshiba
recommends replacing. The problem I have is that the pads for these caps
come off easily when you are desoldering the caps. You have to use a low
temp iron and chipquick (an alloy that melts at about 200 degrees) to remove
these caps safely. I believe the *H82 is having the same problem.
Currently Toshiba is out of the hyper boards ($179 when in stock) and
recommends sending them in to PTS for repair $139.00
Problem as I see it is that PTS does not replace all 16 caps they just
replace the caps that are bad at time of service.
