We tend to conclude people's percieved technical qualifications
by the nature of the question and how it is asked.

Yeah, I know the ones... " TV won't turn on: what is problem?" or "CD
player won't recognize disk" to name but a few common posting topics.
You're right, BUT, the OP had conducted some preliminary tests such as
moving to different outlets, etc. Someone with enough smarts to try even
the simplest diagnosis might, MIGHT, have it in them to learn something.


I suspect you haven't tried to repair a recent model lately?

Read the OP, "old Logitech sr-30".

After solder joints, I'd tend to suspect
output transistors or IC amps, then any type of mixer/crossover
IC's.

Some/most of which are likely house-numbered and maybe even
proprietary. Good luck. Modern, cheap, mass-consumer stuff
like that was not built for repairability, even by professionals.

Not necessarily... these things are made CHEAP and often use many
readily-available parts. Logitch is not and has not been a big name in PC
speakers, they might not have had the volume of production and sales to
justify a custom/proprietary IC design/build. Can't hurt to look if he's
not paying shop labor rates, eh?

Just my 2 cents.
