I have a Panasonic SA-AKX74 and it's showing f61 error even when there is no speaker connected. how do I fix this

SOURCE: F61 error

I had the same problem, and I had to replace the fan on the unit. The fan would not turn on at all, so the computer would tell the unit to turn itself off. After the fan was replaced (which is relatively simple) it works like new.

First re solder any dry joints on Transistors Q502, 504, 507, 515 & CN500, IC501. If there are no dry joins replace IC501 (STK470-0??) & maybe D501 (16.V) zener

As far as I can know, F61 means your output IC is dead. Contact a service centre in your locality for repair!
