hi i have a technics stereo and as i increase the volume it cuts out and returns to standby. It does it at various volumes.I have checked the wiring which seems to be in order. the speakers were the original sold with the appliance.I did put in headphone speakers to the socket and put the volume to full load and it did not cut out or switch off if that helps you ?
-   I am getting a system shut down after a few minutes of play. I have found that giving a hefty clout has the desired effect although this is probably not the best solution. However it keeps cutting out more frequently as time goes on. Also I get a NO DISC indicator when there is a clean disc loaded.

The headphones are powered in a different fashion than the speakers and do not use anywhere near the power. The basic problem here is that you are likely getting DC current into the last output stage of the amp. This can be a failure of a part in the front end or within the output section itself. Depending upon your specific model, the repair cost could be as little as $15 for parts to over $75 for parts. Add in the local labor charge for the complete repair cost. If you can update this with the model number, I can provide yu with more specifics.
