Hi Guys,

Has anyone had any problems with there HK 630? Mine was working great up until 2 days ago.

I have owned it for a month now and up until two days ago I didn't even realize it had a fan in it. When it turns on it is really noticeable.

At first it was no big deal to my, it was just the receiver wanting to cool itself down. Then it kept doing it every 10 15 minutes? The wierd thing is that I wasn't playing anything loud at all! I had the volume at about -40 and was watching Pulp Fiction in DD.

Then, the receiver shut itself off! I thought, okay, maybe I hit the power button by accident. I turned it back on and in about a minute it shut itself off again! I felt the unit, it was hot, but not super hot. There was no smell coming from it either.

I recently re-arranged my livingroom (2 days ago, coinicidence?) and I am using a different plug-in. The power bar I am using is pretty much full and is a cheap one.

My set-up is a VP150, M60's, QS8's and a SVS sub. Have any of the HK630 users on this board had an issue like this? I really hope that I don't have to send this away for a warranty repair. I live in Canada and I purchased this from the US. Due to CSA I will have to send it back to the US to get looked at if it does need some work.

One more thing, it has been hot in Calgary the last couple of days and I do not have air conditioning. It has been pretty warm in the house all day (around 77-79 degrees 26 celcius) do you think that could cause a problem?

i am no expert on HK or electronics, but i can tell you that the power strip can make a difference.. if the powers trip you have is cheap, and cant handle a lot of joules, then the receiver could be struggling to get the power it needs, thus causing it to shut off. they make power strips that are specifically designed to handle the high joules of electronics like computers, receivers, and amps. i would see if the one you have is rated, and if not, spend the extra $30-$40 bucks for a good, high quality power strip that is rated for high usage items. i think it needs to have a joule rating of over 2,500..

i will be honest, i aint exactly sure what a joule is, but i know that if you have an old/bad/poor quality power strip, then you can , and will have probs with your equip.

Lest my physics education decieve me, a joule is a measurement of energy. I could be wrong, but I believe the higher joule rating the more energy it can handle. Just like wattage rates how muc power an amplifier can deliver. But wait, now I'm confused...

A joule is a quantity of energy, a watt is a rate of energy flow. 1 watt = 1 joule/second. A volt is a measure of electrical energy given a certain flow of electrons. 1 volt means that 1 joule will be produced if I coulomb of charge flows through the circuit. (1 coulomb = 1.6 x 10^19 electrons).

Cool, I picked up a 2655 Joule surge protector from the Shack.

Got the Blekin Maximum Series, hopefully this will help.

I will be a 630 owner this comming tues myself! Anyway was thining if that doesnt help I'd be there is a bad temp sensor on the unit, since you say it turns the fans on withotu it being hot then even off its probably misreading thinking the unit is overheating when its not.

Either way prolly have to service it.

Did the powerestip work? Does someone know if simply plugging the reciever straight into the wall is a bad idea. I would think this would be one way to get maximum power. Is my logic wrong?

I don't know if it will work yet, I am still at work. I will reply later, as I am heading out for a few after work pints.

We refer to them as 30-packs in Texas. Nothing like 30 12oz. cans of Cold Coors light!!

COORS LIGHT!!!!

please jc, you are givin us texans a bad name!!

Coors Light will do that to anyone, regardless of what state you're in.

Hey Din, I'm a H/K 630 owner. I've had this happen once. Not the fan, but the sudden shut off. I have no idea what happened. It's like it rebooted itself. This was months ago. I haven't had it happen since. I sometimes run my setup all the way to reference level (0), but average around -25 to -15. Funny you mention the fan because I haven't had the fan turn on once...I actually said to myself the other day "I thought this thing had a fan?".

At -40 I can't imagine it tripping all of that. So there must be something up. Let us know how the power strip works out for you. One other thing to make sure is that your receiver has ventilation. It'll need to use that fan if there isn't enough clearance for heat to "rise" and clear itself through the vents on the receiver.

Good luck. Let us know how it goes.

Around these parts (New Mexico) Texans already got a bad name. He He He. ;-)

Just kiddin with ya Big John. Settle down there old feller.

My HK-630 is in a room that's pretty hot this time of year. I'd say it averages around 80+ degrees F. at times. I never had the fan kick in yet.

It does seem to have a bit of a hard time locking in on the Dolby Digital signal at times. The HK goes through this wierd auto detect sequence where it searches the analog and digital lines. Is there a way to switch this to manual? Once it locks in it is solid. But the search/detect feature can be a bit annoying.

It's sounds like what you're talking about is one of it's natural "quirks". There's about a two second delay after it detects a new signal. For instance when you watch a DVD, most menus are in 2.0 Dolby, but when you select and start the movie it switches to 5.1 Dolby Digital, in that transition there's a delay...a mute if you will, then it finds the signal and stays on it fine after that.

Din, a surge protector should have nothing directly to do with what you're experiencing and just plugging directly into the wall socket is fine. Examine your wiring to see if possibly a strand has come loose and is shorting out the receiver. Even if you don't see anything wrong, disconnect and carefully re-connect your wires.

Well, the new surge protector did nothing. Recently the receiver was actually turning off every few minutes.

So, I checked all of my wiring (I recently put banana plugs on so that was quick and easy). I started to change the setup back to the way it was when it was working properly. I removed a new speaker, still didn't work. I removed a new DVD player, still didn't work.

So, finally re-read the advice in this thread and came to JohnK's response. I unplugged my receiver from the Surge protector and plugged it straight to the wall.

There have been no problems since. Everything is working perfectly.

Well I spoke too soon.

The unit now just shut's off all the time after about 1-2 minutes.

I have unplugged everything from the receiver, except the power cord and it still shuts off in 1-2 minutes.

I tried the "reset" feature this receiver has, but too no avail.

Oh Well, I guess it is off to the shop. Have any other Canadians had any issues getting warranty work done (in Canada) on items purchased from the US?

that sucks man..sorry to hear that..

hope it gets fixed in a timely manner, and you are back to HT bliss!! and hope the cost is low, if any?? i will keep my fingers crossed for ya.

I had similar problems with a refurbished HK AVR 125. It turned out to be an internal grounding problem. After a couple of trips to my local authorized HK repair shop. HK deemed it a lemon and sent me an AVR 130. Good luck-sorry to hear you have to go to the shop-I know the feeling and feel your pain.

Well, I have hooked up my old KenWood (really old) and it sounds okay for the interim. The only problem is, now i have 12 guage wire running in the room with banana plugs. This old receiver won't handle banana's, or 12 guage wire.

Oh woe is me. Hopefully the HK will be an easy fix.

Din, yeah if it shuts off with nothing but the power cord connected, it pretty much has to be an internal problem that'll need repair. On temporarily connecting the old Kenwood, taking off the banana plugs and trimming off enough of the 12ga strands on the end so that it fits easily should work fine.
