KLH Answered Questions & Fixed Issues

Generally speaking, an amp protects itself from heat, shorts and overloads.

Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

If you mean a blank CD-R to RECORD audio, then the SONY digital AUDIO MUSIC discs are the ONLY brand that work anymore. Imation has destroyed the way that Memorex, Maxell, TDK and Imation have made their AUDIO recorder CD-R's. The only ones that will work have a blue-green tint, and SONY does have that, while the Imation junk switched to a golden color that does not work consistantly at all. Does that answer your question? The SONY MUSIC Blank Audio CD-R's are available from Walgreens' stores and online from Amazon.com vendors. Let me know if you need more info.

hi,
speaker output amplifier of u system may be damage. that's why it goes off. check the out put amplifier.
ok

There are a couple of them on eBay...

I saw this post. I have the same problem with my 10-100.

Static is good - that means the receiver is working. You just need a good antenna to get the radio stations better. It should work with a CD player - connect one hear what that sounds. If it's good, then the amplifier is in good shape.

Hello,
This receiver is only capable of outputting and switching composite video, which is not hd capable. Because of this, I would recommend you use it for audio only. Connect the audio portion of your source to the receiver, and the video portion directly to the tv. By connecting it like this, you have the ability of viewing HD sources on your tv(if tv is capable of course) and still enjoy the 5.1 surround sound that your receiver can provide.
Good Luck

I do not know this dvd player, but on most anything with closed caption, you hit the cc button on the remote until you come to '0' or 'off'. As CC has about 6 channels it can use, but really only channel '1' is used. So you might have to cycle through the CC channels until closed caption disappears. Hope this helps. You might also have a setup menu on this DVD where you can control the CC.
Just cycle though it till you get to '0' or off, exit the setup menu.

I have the same amp. there a two ways to use it: The phono plug inputs are low level, are for use as an amplifier only, and their only output is the subwoofer output. In this case, any stereo satellite speakers would be driven directly from your stereo amp.
The high level inputs are meant to be driven as the same as speakers from your stereo amp. A circuit inside samples the bass and directs it to the sub amp and output. this same circut passes unamplified outputs to the satellite outputs. PM me at [email protected] if you need further info.

KLH enter the US market at 2004.
The source of the problem is the power supply board.

If you are handy then you can inspect for leaky electrolytic capacitors.
Replace the capacitors with the same value.

If most case you can fix the unit by replacing few capacitors for under $15 and one hour of your time.

I have the same problem, a few months ago I plugged it into the wall socket, turned it on, then it just hums. Never smelled any burning until I opened it up. There are Two Large Electrolytic Capacitors on the main amplifier board that have completely leaked. There are three resistors that got so hot that the center of the board is burnt black. Next to those three resistors are a bunch of smaller electrolytic capacitors that also have scorched marks surrounding them, although there appears to be no leaking.

The last time I used the subwoofer, it worked great as it has for years. I unplugged it for a week and then when I went to use it, it started humming. I am an electronic technician by trade, I don't think its worth the time and materials to replace all of the defective parts. I suspect that the isolation transformer failed that then caused the main board to poof. The fuse on the outside is on the AC side and is fine. Which indicates that the disturbance is on the other side of the transformer. I do not have a schematic but the main board fuse (if there is one) failed to prevent a full on frying. The control board looks undamaged. If I can find on ebay a junk one that is for sale, I would replace the transformer and main amplifier board. The speaker appears to be ok, but I measured the resistance and it registers 3.2 Ohms. Which is odd, considering speakers tend to be in the even numbered categories such as 2, 4, and 8.

Hope this helps, I gotta buy a new subwoofer.

From your description you have bad connections on the display board, or intermittent power feed from the main board, it will take somebody that is handy with a soldering iron or a professional to check it out.

I'm sure a manual exists for each. You might find them at retrevo.com
