Wrong forums I know, but someone may have a clue.

My admittedly cheap Bush Hi Fi Sytem consists of 3 components, but the
Amp I notice no longer
generates output on Left channel.
Digital Tuner/CD player fine.

I've checked wiring of speakers and reversed connections between left
& right, and it confirms
fault is in amplifier output.
Taking apart hoped may have been blown fuse on the pcb but none of
those inside at all.
Will check for dry joints in relevant area ie channel outputs.

Any other suggestions afore I bin as to which component failure likely
to be in appreciated;
otherwise off to Richer Sounds!.
Thanks.

If it has a mono switch, try that. If it makes both work, its in the
preamp. If not its the power stage - fuse bad wire or more likely blown
transistor or chip.

Perhaps you might find something here.
http://www.repairfaq.org/sam/audiofaq.htm

You will at least need a DMM and be able to take some readings with the
item powered on. Being stereo gives you two identical halves of the amp
to make comparative measurements.

What's the model number. Maybe (but no promises) a schematic might be
out there.

But given the price of these things, maybe a replacement might be for
you. If your tastes in music are purely for background entertainment
walking into a hifi shop is unnecessary, and cheap integrated compact
systems won't be found there. I'd try John Lewis or Currys over Richer
Sounds in that senario.

Just attach both speakers to the working channel. Next time try a
decent second hand item instea of new junk.

Come on, in actual fact these cheap items can sound nnot bad. The weak link
is normally the speakers I find. Of course they are not going to shake the
walls on organ bass notes but they can sound reasonable. Also think more of
them really should spend five pence on an aerial socket as well instead of a
bit of wire.

Gives fm a bad name!

indeed, on carefully selected music. But as the OP's story
demonstrates, as well as the sound being second rate, the life
expectancy is poor too. So TCO per annum is higher for low quality
goods than with good quality second hand kit, of which there's lots
about at very low prices. Plus the added hassle of getting replacments
every 3 yrs as it breaks.

I recently repaired a v expensive (in its day) Japanese AV amp. The
protection was cutting in so it powered down just after switching on.
Turned out to be one of the surround amps going unstable and triggering
the LS protection. That amp design was based around a standard driver chip
- but they had left out some of the components in the makers spec sheet
for the basic design - including the Zobel network and output series
choke. So the old bean counter method of removing components until it
stops working then replacing the last one...
Some local smoothing on the HT rails sorted it.

I take it this is one of those items that looks like separates but is all
powered from one basic unit in the case.

Two things to look for. Sometimes these items use modules for the sound
output. They tend to be screwed to the biggest bit of metal inside. Its
highly likely that one of these has failed, and if its not too old one can
fix them by replacement.
There was one maker of these badged systems who pushed the boat out big
time and put two identical voltage regulated supplies in, one for each amp,
but fed from the same transformer of course. Its possible one has failed.

Mind you unfortunate thhough it may be, most of these, if they need someone
whos time costs money to fix are uneconomic to get sorted. Its cheaper to
just get another Chinese built box instead.


You might hhave problems if it contains a tape machine of two though.

Can't you make your reader ignore all lines beginning with more than one
right chevron ?

That would eliminate all comments but the ones from the post you are

Yeah - almost as annoying as top posters and those who put their sig sep
above the text that they are replying to - so it disappears from the
thread

Do you think you could look up and learn how to use a sig sep properly ?

Just because one blind poster can cope with news groups doesn't mean that
others can do the same.

Most people I'd imagine, these days if reading on a server download like

needed, even after a long time. Add to that the fact that if they really

I don't miss the mouse now, I got over it. Now get over the pedantry of old

Brian, you miss the point. When one enters a social space, it is customary
to obey the "rules" of that social space, or be thought a boor. uk.d-i-y
is a "bottom posting" newsgroup. It is better if everyone goes along with
the customs of a newsgroup.

It is not a "custom", it is actually a part of an RFC. It also tells you how
you should trim posts.

I and, I am sure, most people on here have no problem with Brian's top
posting but do get a bit fed up with the people who do - many of whom
haven't even bothered to read his sig.

Like Brian, I also get fed up with replies where the original, often
long, post isn't trimmed yet most of it is completely irrelevant to the
reply content.

I have a solution for Brian which should keep everybody happy - to
delete the original post in its entirety before writing his reply. He
might need to keep a separate copy of his signature to copy and paste in
at the end, as that will almost certainly disappear as well.

Problem solved ...
