Heysan,

This newsletter is created just in case, if someone need the informations.

1.
How to open the cover

The monitor can be separated by sliding a thick guitar (plastic) pick along
the edge where the two halves meet.

See perhaps picture ...

2.
How to repair power-off

I found 3 defect capacittors (10v 1000 �F), named C823, C824 and C825
and replaced them with 16v 1000 �F.

See perhaps picture ...

How did you determine the capacitors were defective? Visually or test?

(Sorry, but my english is very bad, but I shall try to do my best:)

Well, ...

As You can see on my website, I found some advice, before I started,
so I knew, what I perhaps should look after.

(The advise was not so easy to find and a "little" bit defuse.)

when I opened the cover, there were non capacitors (10v 100 �F), but on
the output voltage, there was another one (10v 1000 �F).

It looked like, it was going to blow up, and this is normaly a sign of defect.

(2 other capacitore looked in the same way.)


So my answer is ... visually.


I tested then afterwards, and non of them seems to be wrong (on low voltage)!

But because of the advice, I replaced them, and the monitor then worked
again ... :-)

Thanks, English is fine. I remember I got a free 5.1 receiver and
speakers that was not working. Found a bad cap (buldging) in the subwoofer
and shorted speaker. Fixed good as new for basically nothing.
