Panasonic RR-830 Desktop Cassette Transcriber / Recorder - Answered Questions & Fixed issues
I cannot press the record button down and the
The buttons on this machine are gated with a mechanical mechanism (under the buttons in the machine -= you can't see it) that acts as a "gate" to control how the buttons behave. This mechanism is probably stuck and needs to be looked at by someone with mechanical inclination - short of calling customer service for service locations. It shouldn't be that expensive to fix. Good luck.
I cannot get the foot
With the foot pedal connected, you need to push the play button on the unit. Then the pedal will operate.
Machine will play cassettes but
Most likely the unit needs new belts. Also possible that a switch has broken. the switched is underthe tape deck on the circuit board.

The headset you are using is a stereo headset. This unit uses a mono headset. Look at the end of the headset. If there is 2 black rings, it is stereo. You can get a stereo to mono adapter at Radio Shack for about $2.50.
High pitch sqealing noise
This is caused be a bad record switch. As a temporary solution, incert a blank tape, push the record switch, then stop. Repeat about 10 times. This may clean the contacts of the record/Play switch but it will probably need to be replaced.
High frequency squeeling
Call tech support! That's why these people get paid. Sites like this wouldn't need to exist if they did their jobs correctly!
I have a panasonic sa vk880 and it wont give sound outputs, when i click on subwoofer button or surrounded enhancer it says error, please help
Try disconnecting all of the speakers except the left and right main speakers. If it works, check the wiring at the back of each speaker to make sure there aren't any shorts between the terminals. Better yet, just inspect the terminals both at the audio unit and the backs of the speakers. Stray strands of wire reaching across to the other terminal or exposed wire on the other side are a common problem.
If you have that all cleaned up and still have the error, you may have shorted transistors in the output amp of one of the channels, very likely the subwoofer. This may be caused by shorted speaker wiring, or the amp may have failed on its own. In either case, you would have to replace both of the output transistors for that channel (they may be built into a power amp module, in which case the module must be replaced). This requires soldering skill, and the knowledge to identify the transistors and check them with an ohmmeter. Most of the time, it's a basic job for any skilled electronic technician. (I did run into one model that would have required two days of disassembly labor just to get at the failed transistors - I told the customer that wasn't designed for service and he would be better off buying something different to replace it.)
