Pull the sherwood power cord from the wall for 20 minutes. On the back of sherwood, check all cables and make sure they are in the correct places. Check speaker wires and make sure they are connected. 1)After 20 minutes, turn power on to sherwood. 2) select an input (radio, cd, etc.) 3) Push play. 4) Turn volume to desired level.
Unless it has some kind of "child lock" mode, in which case you should see the manual about how to reset it. It sounds to me that there is a fault on the microprocessor that controls the functions. It's not something that could be solved other than by an engineer.
Look around for a service centre for Sherwood on the net. Richer Sounds in the UK sold a lot of these, they might be able to help you.
I'm assuming 'Kenwood' means a home stereo amp or receiver? If so, the volume control probably just needs to be cleaned. Control cleaner can be purchased at Radio Shack, or a similar store. Just buy a can, and spray a tiny amount into the control, and turn it all the way clockwise then all the way counterclockwise several times. If that doesn't correct the problem, the control may just be worn-out and is in need of replacement.
By design, yes for one pair of 6-ohm speakers used at a time; depends on the sub for the second BUT there is no way to control its volume at the Sherwood.
Turn the volume control to something medium. The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.
Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.
There is a good chance that a common control may have developed a high-resistance or 'dead
You need to hook an antena to the back of the unit (A peice of speaker will do!) you should see a screw in back of uniGood luck and Thank you for using FixYa.
If the volume is controlled with a mechanical volume control, usually a knob you turn or a slider you move, the problem is the volume control device (potentiameter) needs to be cleaned. That requires special cleaning chemicals most people do not have in their home. You would need to take it in to be serviced. This is a very inexpensive repair. Normally only costing about $50 to $75.
If it has electronic controlled volume like a button you press then it will still need to be serviced, but this is an unlikely case with static in volume when using the volume control.
you may be using an equalizer? try to pop-up the volume with all tone controls in flat mode. see if it still cuts off. if this is the first time youencounter this then something must be wroing with either your speakers or your amp. unless your ventilation is not good enoughg, you can also try placing a blower on top of your unit to cool it down
It sounds like your volume control pot has dust in it.You need to remove your cover from the receiver,spray pure denatured alcohol in the small openings in the back of you volume control dial and turn the knob all the way up and down several times and then blow low compressed air threw the same small openings while rotating your dial.That should fix your problem.Be sure you unplug your receiver before performing this procedure.
