Bring an lubricant contact cleaner from radio shack near you and apply the spray over it while you move volume control forward and backward.

HOW CAN I REPAIR CHANNEL ONE ON CROWN CE2000 IT IS NOT WORKING TWO WIRES BECAME IN CONTACT WITH EACH OTHER


The power amplifier section should be troubleshoot for shorted output IC or transistor. If you wish to get some details; visit the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Mute function on the amp


A couple of questions to try and narrow this down:

1) What is the impedence rating for the speakers?

2) When the unit shuts down, will it recover on its own after a little while or do you need to power cycle it to get it to work again?

3) When the unit shuts down, is it hot?

Possible causes of this behavior:

1) Impedence rating too low causing the amp to work too hard and shutdown.

2) Excessive heat (caused by #1?) will shutdown the unit to prevent damage.

3) Possible intermittant short in the speaker wires somewhere? Loose connection?

A little more investigation will be required to find this. A repair shop would run this unit under load and monitor the outputs for heat and any spikes in the signal that could kick in the protection circuits.

Keep us posted on what you find.

Pioneer audio/video receiver damaged


Hi...
The problem is probably that the bad connection "took out" a couple of the power transistors/power mods in the amplifier

If you need a pro to fix it I can suggest someone depending on where you live

Rotel processor bypass for Audio Research SP10


If I understand you, the 'sound' of the AR preamp is what you're trying to preserve. Presumably you're just running a phono through it as nothing else needs a preamp these days.

The multichannel inputs bypass all of the Rotel's processing except the volume. Use the Front L and R.

LOW VOLUME ON MY SL-B35 TURNTABLE


Hi Tim,

You probaably do not have a phono input on the digital surround amp you are using. Your sound is bad for 2 reasons
  1. Your Turn Table has low output level,about 100 times less than a CD player.
  2. You need RIAA equalisation to reduce the treble and boost the bass. This is for replaaying any modern vinyl or LP's
You can get an outboard preamp that matches the output of your T/T to suit the normal aux input on todays digital surround amp.
You can get one online from here. Or if you are keen build one from a circuit here

I am more than happy to answer any other questions you may have about it, please get back to me here, or use the ASK function to go straight to me :) If you are still unsure, have problems, or we need to look at the situation more deeply, then before you give a rating for this advice, hit the ASK button Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

Technics stereo integrated amplifier su-g91


It sound like you have burt the output stage, for some reason, u have over driven the speakers witch blew the output ic's, or have shorted output. To check if you have shorted output unplug the speaker's and try again to see if the mesage goes away, if it doesn't open the top cover to see if you can see if there is burt resistor's or fuses, if so replace them, then try again without speakers connected, never put the volume to max, why ?????? I just don't get it. Leave the volume to 1 or 10% capacity to try thing's or with earphones this is alway's to me the best way, if for some reason it keep's burning fuses, then it is ether the power supply depending witch fuse blow's or the output amp stage, most likely if is the output amp, the two big ic's you see, check on googles with the part # on them this will tell you what they or.

Hope this helps

Bob the builder.
