Question about Panasonic SC-EN7 CD Shelf System
I unknown the output integrated circuit of this product, because the defective is unreadable. Please send me the part number to buy it. Thank you
Hi there OSKY,
I would suggest that you try and obtain the service manual for this system of yours. Usually from the manufacturer or an alternative source.
The model number and the manufacturer are listed on the rear panel of the sound system.
Once you get the service manual it will list the correct part number and the type of IC installed in that particular model..
You havent listed the model or manufacturer for me to search my own service manuals , so I cant provide you with the IC part number...without a good description of it..

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be with your output drivers. Please check for short on the outputs fitted for both the channels. Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise which can be a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board. Maybe the protect circuit by itself is shutting off due to a faulty bias or there is a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the amplifier comes out of the protect mode then check for short on the speakers.Check manual to see if there is a reset or the processor can be a suspect.

Anything that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to any audio device with a standard RCA input. Get a cable like the one described here:
and connect it into any available analog input EXCEPT "Phono". Turn the MP3 player volume up.
