Until you resolve the protect mode, the amp will continue to work as you see it. Protect usually indicates that there is a short in the output section and the amp shuts down to prevent further damage. Since this amp uses discrete transistors for outputs, check each one for a short. Once found, change the entire pair (2SD and 2SC transistors) and any other components in the area that are effected.

The tolerance for timing of an ethernet connection is not so tight as to be effected by this small variation. Your cable will work just fine with a new connector. Note that the tab is there to secure the plug only. If there is sufficient support close to the connection such that the connector can not “fall out”, you don’t need to replace the connector at all. Tie-wrap it to another cable next to it and you should be ok as long as there is no stress on the cable without the locking tab. Dan

Yes this can be repaired, but not easily unless you have experience. The pads must be repaired before the connector is reattached. Also, there will need to be additional support for the connector otherwise it will easily be torn off again. This is not a repair that should be attempted without prior experience. Contact a local repair show and bring along the connector and the board (in a static bag). Dan

If all you did here was to tear off the connector leaving the pads on the board, this can be easily repairs by soldering the connector back on. If the pads were torn off of the board, the repair gets a bit more complicated. It is difficult to see whether or not the pads are intact. If you are not comfortable with soldering things this small, seek a service center that can fix this for you. Post your location for anyone here that may be able to help. Dan

Perhaps the most common cause of this is a failure of a backlight which can be either an entire strip of a couple of strips. While possible, the failure of part of the power supply can happen as well. Without the specific model, I can’t post any replacement part numbers. Please update this with the exact make and model and additional information can be posted. Dan

This is most likely a neon lamp that is used to adjust the speed of the turntable. The symbol is for a lamp. The neon lamp will “flash” at a 60 Hz. There should be a speed adjustment for each selected speed. The ribs on the side of the platter or somewhere seen through a clear plate will seem to stop rotating when the speed is correct. Dan

The most common cause of this is that the belt is not placed inside the unit correctly. Without pulling the service manual for this, I can’t easily describe the belt pathway, but this is where you should look. Check the web for a service manual (I haven’t looked). If you can’t locate it, try looking for similar units. The mechanisms for these don’t vary too much and another model may help to show how the belt is run. If you are still stuck, post your location and someone with experience may be able to take a look and repair it for you. Dan

The error message indicates that there is a problem with the take-up reel side of the camcorder. This can be fixed by someone with experience repairing camcorders and is a relatively common error code. Sometimes you can retrieve the tape by rewinding it to the beginning. This function does not involve the take-up side directly and might work. Basically what is happening is that the system is detecting that the take-up reel is not turning and the camera is shutting down to prevent the tape from “spilling” into the camera which would result in damaging the tape. For references to shops that can help with this, your location is needed. Dan

I don’t have a listing for that model number in my cross reference. Since this is a small dictation device, I would suspect that the belt will be in the range of a PRB type SCX3.5 to SCX4.0 . You may need to open this unit up to measure the belt. These belts should be available from MCM-One and other suppliers. Expect to pay between $1 and $3 for the belt. Dan

I will assume that the receiver is old enough to have a real volume control as opposed to a “digital” one. That being said, older systems have open controls that can get dirty. Using a switch cleaner spray that contains a lubricant as well should resolve this. In detail: volume controls have a fixed resistance coil between 2 of the three tabs on the unit. The third is connected to a “wiper” that makes contact with that resistance coil (or flat surface) and varies the resistance for the circuit which is seen as a change in the volume. If there is dirt, dust,debris present, the contact may be briefly interrupted which will result in the noise that you hear. Using the spray will not only remove any debris from the unit, it will also provide a protective layer that should prevent the problem from recurring for quite a while. This is a common failure that is easily remedied. Dan

For non-phone repairs similar methodologies apply. The difference is the cost of the parts. In my business, I have been repairing audio and video devices for over 30 years. I stock all of the common transistors, capacitors and resistors which probably cost me over $500 initially, but saves customers’ time and me space since I can usually provide a quick turn-around time on repairs. Storing component parts takes a lot less room than receivers or cameras. For the model specific parts, I generally order 2. This takes care of the existing repair and allows for another repair with no wait time.
