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.

How to repair power-off

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

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 ľF), but on
the output voltage, there was another one (10v 1000 ľF).

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.
