Question about Panasonic SC-AK300 CD Shelf System
Hi, I'll quote directly from the service manual Error display - F61 Problem condition - When POWER is switched on, power become off automatically. During normal operation, if DC DET become L, PCNT shall become L and the error display on the left shall be displayed. (IC501) What *I* think that they are trying to say is that the protection circuit will activate if DC appears on the speaker terminals. IC501 the audio output chip may be faulty.

The abnormalities an output or power supply circuit of POWER AMP.
In normal operation, when DCDET2 goes to "L" (Low) (Not during POWER OFF condition), F61 appears on FL Display and PCONT goes to "L" (Low).
This is due to speaker output has DC voltage or fan is not working.
