Kenwood KR6030 was smoking - now fine???

[rhinotone]

Hello,

I'm a new member to this forum but I have been using for research for a while now. I just purchased and received a Kenwood 6030 receiver from eBay and when I plugged it in for the first time it smoked. So I unplugged it and contacted the seller. He responded quickly, apologized, told me to keep it and immediately refunded me the money ($100). He also assured me that it was in perfect working order when he shipped it.

I was contemplating taking in it for repair or just tossing it in the trash and I figured I'd open it up and look for anything obvious. Upon a visual inspection I saw nothing that looked burned or melted. The only issues that I could see were the fuse board was not screwed down and there was a loose screw floating around in it. So, I removed the loose screw, fastened down the fuse board, hooked up my Advent One's and now it works perfectly and sounds great!

My very long winded question to all of you is; do you think it's safe or I'm I going to come home and find my house burned down because of this receiver?

Thank you all in advance for any help!

Cheers!

Are the insides very dusty?, maybe the trip loosened that dust?. Now, if something is hot enough under the hood to make smoke!, humm...
I would use an air compressor, dust it off outdoors and definately NOT leave it alone, working. Try using it for a while while watching it, see what
happens.

I blew any dust before closing it back up. I think the dust theory is a good one! It's been running all day, no fire (or smoke) yet! Thanks for the response!!!

It's easy for a loose screw to get across something and cause a short. Be nice to figure out where it came from. I prefer things to either work or not work, or at least leave a solid clue. Mysteries cause me to lose sleep.

I'm gonna set it and forget it. You know the coolest thing is that I'm loving the warm nostalgic tone of this thing and my 14 year old son is digging it from a purely modern, "this thing sounds great" perspective.

if it keeps working maybe its worth doing the right thing and giving the seller some money back .
cant figure out a loose screw being the thing that smoked though . i can figure it would cause something else to smoke though .
sometimes things will appear to work just fine fine with burnt bits . maybe part of the protect circuit or something .. did you check both sides of the boards ?
another thought it might be insulation on the primary side of the transformer wires that smoked a bit .

Yes, definitely considering that...although it would have cost me 100 bucks to have it looked at and the seller shouldn't have shipped it with the fuse board floating. Thinking I'll let it run and keep an eye on it for a bit. Did not look at both sides of the boards. I'm not a tech and didn't want to push my luck.

**** can happen to anyone . screws can fall out in shipping . i know some shipping companies dont give a **** about throwing your parcels around .
even if it was loose already the seller was most likely unaware of it . sorry to rant on but this **** can and does happen .
anyway back to thread .. i personally think anything you plug into the mains power is a fire risk ,be it brand new or 100 years old . fully serviced or never touched . **** can happen ..techs would be out of work if things didn't break down . never trust anything .

Not to beat a dead horse but, the device was not packed professionally. It was mummified with plastic wrap and cardboard but not well padded / protected at all. No other screws were in the packaging. I think it was a "you get what you pay for" situation and I just got lucky. Anyway, thanks again to all for responding!

Keep,,, is my advise; keep the $ AND an eye on the receiver for a good while!.

That type power switch is noted for failing.

I would give the guy his hundred bucks though - seems like the right thing to do

 

[dane79]

I'd give him his money. But that is weird. When I got my subwoofer amp there was a huge spark by the transformer when I was adjusting the gain knob testing things out, nothing happened since then though so keep an eye on things for a couple weeks and you should be good!

It might be prudent to check ALL the mounting hardware, ground lug connections, and mechanical mountings such as clips, board stand-offs, and similar hardware. Rough handling may have loosened more than one fastener.

As for the rest of the unit, a thorough inspection of connections and components might reveal anything which could have overheated as a result of a loose screw shorting something.
