Question about Harman Kardon AVR 630 Receiver

Occassional sound from surround right channel

Occassionally I get no sound from my surround right channel. It works for months at a time and then stops for months at a time. It doesn't matter what input I am using (haven't tried direct input channels). When it isn't working, the static builds in volume until it pops and then goes quiet. It repeats until I shut off the unit for the day or unplug the speaker. I have tried changing speakers and even houses and couldn't lose the problem.

I'm not sure how to diagnos if the channel was always dead, and it is even harder to troubleshoot when it isn't broke.

    This unit is not under warranty (they only made it in 2003 and 2004 and it has a 2 yr warranty). I am looking to troubleshoot the internal components/connections on the pre-amp board as I believe that is where my problem is.

I own a Bernina 2000DE Serger which I purchased new many years ago. I've never had ANY trouble with it, and am quite experienced with sergers. However, when doing quite a bit of sewing on fleece the last...


Has it been serviced at all during your ownership of the serger?

The loopers can be knocked a little out of timing resulting in the skipped stiches on the heavy weight fleece occassionally. It sounds like you have tried all the usual fixes and know what you are doing.

Only other thing that might cause skipped stitches could be using a sharp needle rather than a ball point on the fleece. Otherwise maybe time for a trip to the shop??

Hp 6200 makes machine gun sound before printing, when the print carriage goes all the way to the right is when i hear the machine gun sound, it still prints fine.


Hi,

This is quite normal with this series of printers. Happens on my 6310. It "machine guns" only occassionally (once a month), and then the gunning noise slows down slowly, then the print starts. Might be shaking the head to clear ink rigorously or something.
