To Next PageTo Next PageWhy won't my Panasonic Home Theater System turn on and the standby LED is off?
If your Panasonic Home Theater System cannot power on and the standby LED is off or flickering, the issue might be a faulty AC cord or loose connection. Check the FFC connection and alignment from the SMPS (JW2) to the Main (CN2004). It could also be due to a P5701 solder crack or an open F1 Fuse.
What to do if my Panasonic Home Theater System powers on then shows F61?
If your Panasonic Home Theater System powers on but then displays 'F61', it could be due to a short circuit between pins 11/12 and 13/14. Inspect the SMPS Circuit (Item 17.7) for terminal pin count on primary and secondary terminals. Also, check for solder cracks, dry joints, short circuits, or open circuits on the SMPS P.C.B. (Fig. 1).
