Question about Audio Players & Recorders

1 Answer

Power no sound to audio reciver

I have a Sherwood Newcastle receiver, model R-925. It is about 8-10 years old. It has been great without issues. The other day when it turned on, we had no sound. I checked all the connections and even plugged in an old pair of headphones in the older fat style headphone jack. No sound. The unit is no longer under warranty, so I thought there may be fuses inside, one of which had blown. I just checked it and all the fuses are intact. All the knobs, tuners, switches work.
I do not have nay repair facilities close to my home that I know of. I know this problem is very vague, but does it sound like something major, as in tank the unit & by new. Or, does it sound like something minor which can be easily fixed. I appreciate any hep or guidance you may be able to offer.
Thanks in advance,

    Thank you. Is this something one can do himself or better to take to a shop?
    I have not idea which board is the amp302 board.
    Also, I don't quite understand what you mean in option "B" "Pulled out of correct speaker switch"?
    I really appreciate your help.

According to the service manual. If the Power Indicator Light works and no there's no sound, then: (A) Trasistor Q215L/R or Q216L/R on the AMP302 Board is faulty.
(B) Pulled out of correct speaker switch.

The transistors you can look up the price on the net, it says they are: BKTC3200.

Sherwood rx-4105 receiver that when turns on stays on for approximately 4 seconds and then shuts down.

Sounds like you have power supply issues, pull the cover off and see if you can see any bad capacitors for starters

Connecting Samsung TV to Sherwood Newcastle R 865 Receiver using optic cable.

The problem might lie with the TV itself. The optical input might be switched off. You can check if the signal is coming out of the TV. With the optical lead plugged into the TV and the TV on. But not plugged into the Amp. You should see a red light come out of the unconnected end. If you don't see that the socket is switched off at the TV end. It might come under sound in the menu, or options, or digital audio output. Or a combination leading to the other!
If you see an option for Dolby Digital, set that to on as well. Some HD TV channels use Dolby, but others don't. It will only come on with certain films and TV shows though, it should switch your receiver to the Dolby setting, just like DVD and Blue Ray discs do.

I have been having my receiver for over 1 year now and just yesterday when I turned it on, within 5 secs ,the receiver turns off. I cannot get it to stay on.......Any suggestions......

most likely reason could be a short in one of the speaker wire at the connector. Check each speaker connection one by one. If this is not the cause then most likely the power supply is cutting off. The unit may still be under warranty if only one year old. Contact your local Sherwood support outlet.

Getting sound on turn-on is intermittent

If you can open the case and check for dust and dirt collection, that might help. If dust accumulation occurs it coats the electronics and may cause over-heating. Over heating will create temporary shorts and in time total failure. Vacuum the interior and make certain the unit has good venation. Warped circuit boards act in that fashion also.

I have a Sherwood Audio/Video Receiver Model RD-6105 that keeps cutting off after 30 sec in use i had it for about 2 years can you tell me what's wrong or how to fix this ?

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.

Sherwood 6500 reciver

check your speaker wires make sure they are not shorting against each other down the line, that will cause the reciever to go into standby.

No High Voltage

I did solve the problem with the Sherwood receiver R6036-R
The problem was a broken solder Trace towards the power cord on the powersupply board.

Thanks for your concern
