    After I had opened the receiver, I found a square black transistor (A958 74 Y) brocken: Only the black ceramic part was brocken in two.
    When i switch on a spark was coming from this transistor.
    Should I replace it? or it sounds more complicated???

When power is turned on, standby light comes on normally, but in any playing mode, the receiver switches off and the standby light flashes.


It looks like this is a common problem with a lot of the Sherwood Receivers. I've had the same problem with my R-125RDS for a while now. Finally hit on solution today by replacing a power transistor. The transistor in question is not on the power amp board but instead screwed to the chassis and wired to the mainboard. I believe it is part of the output short protection circuit. In my case the component was a 2SD2059 (silicon NPN 100V,5A) replaced by equivalent 2SD1407. The transistor seems to run pretty warm so I guess this is why they ultimately fail after a few years.

Sherwood RV-4050R compatible with new gear?


The TV is irrelevant.

BD would need HDMI, digital audio or 5.1 analog inputs on the contol receiver. You have none of these.

Sherwood model RV 5050r - tuner is not holding radio frequencys in memory when the main switch is turned OFF and ON again. Is there a battery that needs replacing or a chip?


Try looking for one of these Memory Retention Capacitors, they cause a lot of trouble like that. It will be in the tuner section somewhere if it uses one. It could look a bit different to this one, so bare that in mind.

Sherwood rv 6030r does not turn on.


Try these simple trick to find out yor remote control working or not....
Point the remote control towards the Camera of a Mobile Camera phone,with the camera on. While pressing remote, we can see a light (Infra Red) coming from its IR LED through the Mobile Camera if the Remote is working.
If the remote is OK, then the problem with the Remote Sensor or related components of the receiver.
