Check the stereo Balance control. If it is set to one end, that speaker won't output sound. If found the setting to this is set to mid-point, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. Surf the site with patience.

I have a Sanyo M7755K mini boom box. I hear music on one side and there is no audio on the other speaker. What can I do?


Hi. Before deciding if the final audio IC is defective, swap the speakers. So you can define if the speaker itself is not defective.

Reorded tapes only play out one speaker


check your cables to the units channel that doesn't work, for breaks. Does the cassette player play back a pre-recorded tape okay? if it doesn't there might be a internal fault.
Check the wires to the tape head to see if one is off.

No audio output


Were you playing it very loudly when it died?

The manual is here for reference...

http://www.docs.sony.com/reflib/docget.asp?manualid=11654&template_id=1&region_id=1&DL=',600,560,10,10,'Manuals'

It discusses troubleshooting this problem on page 50.

When you turn the receiver ON does you hear a light click in about 5 seconds? That would be the protection circuitry turning OFF to allow the amplifiers to function. The delay is to allow the circuitry to stabilize before it sends any output to the speakers. If you don't hear a click the unit is Protecting the speakers due to malfunction somewhere.

If no click and no apparent messages try turning the speakers OFF using the Speakers button directly below the Power button (1/0). This will eliminate or point to external shorts as the cause.


Does the unit click after 5 seconds of Power ON with the speakers OFF? Isolate your shorted speaker or wire problem.


Still no sound at the speakers when you turn them ON?

We need to establish if there is any programming flowing through the receiver.

A quick basic check would be to tune an FM station, if you have a tape deck attached, place it in Record or Record/Pause mode so it can display the input signal levels. You should see the record meters fluctuating with the level of the program selected. If you don’t have a tape deck, run an RCA cable pair from the audio output for a tape deck to an analog audio input on your TV. Select that input on the TV and you should hear the FM station, or anything the receiver is configured to play. If it's silent then there is no audio signal circulating in the receiver to get out to the amplifiers.

If you hear the program on the TV but not through any attached speakers, then the amplifiers are all disabled for some reason.

If there is no audio flowing through the receiver the problem could be a switch in the wrong position, source not selected, muting on or a multitude of other things.

Let me know how this turns out.

Play back on Sanyo mr-929 reel-to-reel tape recorder is backwards


I also have an MR-929. The information that you need is in the 'Stereophonic 4 track stereo''. As stereo is only two tracks, there is another 2 tracks in addition to the one you are listening to. Wind the entire reel to the empty spool, and then play that. As you have to physically turn the reel over to do so, you should then hear the other tracks (or track, if recorded in mono).
I use my 929 to play my parents recording of my family from the late 60s, which were recorded on a valve (tube) Ferguson machine, which had a green "magic eye" level indicator, which as a child I found fascinating!

Can hear crackling or spitting sound when selecting HI-FI


The "crackling" sound you describe sounds suspiciously like mis-tracking. That is: The result of the Hi-Fi heads (which are on the rotating video headwheel or drum) not exactly following the recorded tracks. Have you tried adjusting the tracking slightly? The reason this happens is that the Hi-Fi tracks are MUCH narrower than the thinnest video track (used for 6 hours per T120 tape). Tape stretches and shrinks as it ages. Video recorders wear with normal use in such a way that the tracking changes. The problem is often worse with tapes recorded at the SLP (6 hour) speed because the servo cannot correct errors as fast when the tape is moving slowly (on some machines only). Tape quality also counts...and manufacturers change their formulations without public notice. All these things can lead to "archived" tapes being lost. Solution: Use the best quality tape you can afford, not the cheapest; record at the highest possible speed. Store the tape carefully. Never use a cheap "rewinder" because they can over-tighten the tape causing wrinkles, stretches, and other kinds of damage.
