Pre-amp pins were recently removed to add more hardware and now there is no sound when on.The hardware that was inserted into the pre-amp in-puts(red and white) was the Spin It Again program that converts analog to digital from records and cassettes to computer files for conversion to cd's.

I suspect that the pre-amp stage in you amp has failed. What you are hearing is the power amp on full volume. But with no pre-amp to boost the signal it's to low.
What we do know is that the sound is going into the pre-amp and out for you to hear it. This could mean that the power to the pre-amp stage is low, but still present.
Pre-amps these days mostly consist of a single IC. That could have failed, or it is not getting power. Since it would be possible to test the voltages to the IC, one pin should have something on it to the region of 6 to say 20 volts going into it. If the IC has that going to it, it has failed. If the voltages to all the pins are low, then you have a power problem.

Hi Eleanor,
Without a specific model number I can only give general information, but, Kenmore fridges are all about the same, so here we go. Take a close look at your unit. You should observe several small plugs inserted on the side of the doors that don't have the hinges currently mounted. These inserts cover threaded holes that are used to mount the hardware for the hinges. If your fridge has two doors one above the other. remove the top hinge hardware, lift the door up off of the bottom hinge pin. then remove the bottom hardware on the top door. Typically the mounting screws are either phillips head or 1/4" hex head machine screws. You should now see that there is now a threaded hole in the same position on that side as the plug in caps on the other side. remove the caps from the one side and insert them in their respective holes on the other side. the door hinges will attach to the now exposed holes on the side that the plugs were removed from. But not yet. First remove the top hinge hardware on the bottom door, lift the bottom door off of the bottom hinge, and then remove the bottom door hardware relocating the bottom hardware to the other side. Install the bottom door onto the hinge pin of the bottom door hinge. Close the door then install the top hinge on the bottom door. Next install the bottom hinge and hardware for the top door, set the top door on the installed hinge, close the door add install the top door top hinge and hardware next. Same with the door handles. All of this info applies to the doors and the fridge itself.

If your talking about the thump thump sound thru the sub when in standby mode, here's a fix if your good with a small soldering iron. Remove the amp from the sub. Locate U301 on the limit curcuit. (the small circuit card standing up right) Replace U301 with a TL074IN (www.alliedelec.com part #248-0012) .35cents +S/H also remove R263 from the preamp board,add a new 1N4148 diode(#935-0242) .05 cents to the pre amp board. Connect the Anode of the new diode to the Anode of D101 and the Cathode of the new diode to the Cathode of D108. Replace amp and test. Thump thump should be gone.

It's logical since the headphones jack is connected at the main amplifier. Does your new main amp has headphones out?

If you put the good channel from the deck into the right and then left phono imputs of your amp, the sound should come out from the left and right speakers. If it only comes out from the left, then the amp as a right hand channel fault. Now if other devices work on both channels, then it's the pre-amp for the phono socket that has a fault on it. You should be able to find this by following the wires from the phono socket. If you touch around that pre-amp you should get it to buzz on either channel (where it joins with the main pre-amp). Doing this with a screwdriver will pin-point where the faulty part is (working backwards). PS don't short anything by touching to bits of metal together with the screwdriver.
Magnetic cartridges need a small pre-amp before they can be past to the main pre-amp. That's why you can't hear anything with the deck plugged into another line socket.
If you get signal on both left and right speakers with the above test the deck is to blame.

are you putting the left and right ( white and red ) phono connectors into the phono inputs on the back of the amp? thats the place to locate them. either that or the leads from the turntable are both damaged but i doubt that is the cause? check your inputs on the back of the amp to see if it has phono inputs? if not you might have to insert them in the auxillary input and buy a small pre-amp from a hi-fi shop to boost the signal? good luck

i think you would save time buy just buying a usb mircophone
ive seen them getting very low in price. you risk damaging your computer if you get the wiring wrong.

please put detergent into the main(left) side of the dispenser

Hey dskum i have the voltages connection,do you have an email add, I have also problem in Pre-amp.section the IC is blown,so i wanted to know the number of that IC.The powersupply voltages is normal i have negative and positive 18 only the sound is gone because of blown IC.My e-mail add is [email protected]

Hi mos, Your board uses an AMI bios. You can see the specification here: http://www.ecsusa.com/ECSWebSite/Products/ProductsDetail.aspx?detailid=46&CategoryID=-1&DetailName=Specification&MenuID=1&LanID=9
AMI BIOS beep codes
1 short = DRAM refresh failure
3 short = Base 64K RAM failure As noted at this link: http://www.computerhope.com/beep.htm
Suggest you remove your memory & re-seat one dimm at a time booting after each re-seat. If this is new memory insert old just to check board function. Shut down & try new memory. It wouldn't hurt to check against the manual pg. 6
2 DDR (184 pin, 2.5V) + 2
SDR (168 pin, 3.3V) DIMM sockets with a total capacity of 2
GB system memory
