RE: Anyone own a Yamaha Home Cinema Amp ?

["Keith Doxey" <ukha@xxxxxxx>]

Hi Dean

If the hum is ALWAYS present there are a couple of possibilities.....

1. Power supply knackered.
2. Earth Loop.

To resolve the problem follow thse steps

STEP 1
Disconnect EVERYTHING except the speakers and see if the hum is still
present. If it is then you have to lug the brute back to the shop. If the
hum disappears you have an earth loop from some other kit.

STEP 2
One by one, plug the other kit back into it. When the hum starts you have
found one of the culprits (it may not be the only one). Continue until
everything that doesnt cause the hum is reconnected and you have a list of
kit causing the problems.

STEP 3
Report back for more specific advice

Hope that helps

Keith

Subject: [ukha_d] Anyone own a Yamaha Home Cinema Amp ?


Hi.

I recently purchased a Yamaha HiTB45 Home Cinema kit - i know its not the
perfect answer, but it suits me...

Excellent sound and love the satellite speakers - didn't want anything too
large in the corners of the lounge !!

Its a HTR5540RDS... but i have a problem.

The speakers humm - and its a bl**dy annoying humm.

I've removed the amp from under the tv - wired the speakers on the floor
straight to it, and still there is a continuous humm - its still there even
if you mute it ??

Anyone got any suggestions ?? - I guess i'm going to have to send it back,
i'm sure it wasnt doing it when i got it (2weeks ago)


Thanks



Dean.
