Where to get H.T. Amplifier fixed

[joetama 5,000+ posts]

I probably will if I cant find somewhere else to do it.. I just have a hard time believing they are the only electronics people that can fix H.T. amps... Gotta an electronics store that can do it, or an electronics repair shop, or someone on a forum that fixes amps.??

Well here is the thing.

What the manufacture is probably going to do, is just replace the board with the problem. Just swap it out.

If you send it to a 'repair shop' they are going to have to find the problem, fix it and send it back to you. There are several issues with this. One is that there is really no promise that they fixed the problem. Many times in circuits things hide. So, by fixing one problem you might have only put a band aid on the cancer. Second, is the complexity of modern circuits. Years and years ago you could break out a MM and a soldering Iron and fix about anything. Now, with computers controlling most electronics it is harder and takes a higher level of skill than it did in the past. So, for places that fix electronics the techs mush have a higher training level. Which requires they get paid a higher premium rate for their service. Third, since these circuits are much more complex there is a lot larger time in having things fixed. 10 Years ago when you opened up and amplifier it was pretty simple to find what was bad. Find the burnt diode or resistor, if the resistor is a power driver resistor or is on the base or collector of the transistors check for shorts. Not so simple anymore.

Add all of these things up and what do you get? Higher costs. Since most shops have to charge these higher costs many of them went out of business. Which is why the manufacture is usually your best bet.

However, United Radio fixes about anything electronic and they do a fantastic job. Usually aren't too expensive and they are fast.

The reason I ask is it depends on the model if it is worth fixing for that price or not.
There are advantages with going with new models, such as all the HDMI crap. But, if you aren't going to use any of that paying the $250 for a very solid receiver isn't a bad idea.

Sry guys it wasn't Denon...that was the broken cd player we have... The Reciever is the Harman Kardan AVR7000... Very solid when we first bought it.. http://www.hometheatermag.com/receivers/43/

You said that it doesn't pass sound anymore. Does the unit go into Protect?

A receiver like that usually don't go into protect.

Well honestly, what is the receiver worth? How much did you pay for it? How old is it? What is the repair costs?

If UR does HK then I would probably send it there.

A receiver like that? Please explain why this particular receiver won't go into protect?

If the light around the power switch is red then the unit is in Protect.

A good majority of receivers that I have seen don't have that.

If they malfunction in a way other than shorting the speaker cable or something they usually do not tell.

I am going to have to disagree with you. This receiver does have a protect circuit that typically signifies a short in the amplifier. Either in the power supply section that powers the amp or 1 or more blown channels. If his receiver has blown 1 or more channels then the possibility of it being pricey to fix increases.

If it doesn't go into protect. Then a reset should be performed before he takes it to a repair center. Considering he hasn't done on already.

Call Skokie TV Repair in Wheeling. They fixed my Denon a few years back when a lightning strike near the house fried the transformer I belive. Cheapo surge protector didn't do a thing...

They're an authorized repair center for many brands.

Interesting... I do not doubt that the design has some sort of protection built into it. But, I have never seen one with an indicator. Maybe they all have them but they just don't say what they are. I always thought it was more common to see "if the light flashes 5 times quickly and once slowly".

How would one go about doing this reset?

Just an unplug and replug? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Unplug for at least 3 minutes then plug it back in is the first reset to try.

Next would be put the unit in Standby by pressing the

System Power Control button. Next, press and hold the Tone Mode and the

FM Mode Selector buttons for three seconds.

The unit will turn on automatically and display

RESET.

Now the second reset will clear everything. All presets, output levels, configuation, etc...

Typically if a unit doesn't work properly and there is a flashing red light. the unit is in protect.
