Question about Panasonic SC-HT740 System
I had the same problem it took four or five e-mails to find the fans
I found them at the site below
P/N. L6FAJCCH0007 FAN MOTOR (THIS IS THE REAR FAN)
P/N. L6FAYYH0001 FAN UNIT (THIS IS THE SIDE FAN)
Hope this helps

Being a factory trained (Secaucus, NJ) and authorized Panasonic repair technician for over 25 years, I can tell you there are at least 10 listed reasons for an F61 code to appear.
Yes, stuck fans are a possibility. This usually occurs with new units stored for an extended period of time out of the "normal" temp/humidity range recommended (often basement / attic or garage. Getting them to spin again will usually allow the lube to fully access the bearing, solving the problem. Usually using 1 Watt RMS output should get them both spinning.
The other common failure is excessive volumes, blowing the power ams and possibly the regulator system. Also, using ANYTHING beyond the 6 Ohm speakers provided or not wiring them properly will smoke the amps almost immediately. The power amps have differential digital outputs, which in laymens' terms, ARE HOT TO ANY OTHER CONNECTIONS. There is NO common ground like older systems and because of the power capabilities of the output ICs, you're basically "crowbarring" the system faster than the safeties can react. Say Goodnight Gracie...
Good luck, Bugman

I got the F61 error and just tapped the side and for now it went away and the system is back to normal. Lets see how long this last. I also ejected the disc holder and spun it a few times.

The rear cooling fan PN 5010L125 is not turning. The fan has an output to tell the circuit board that it works.

These units are failing thick and fast now and the parts are hard to come by except from other failed units which is always risky. My advice is that if sound has failed on any one speaker output and some simple cleaning of the fan or replacing it with a computer fan does not fix the problem, then it is time to buy a new Home Theatre System. I am the last person to ever want to consign things to the tip.........but even WE have to go there some day eh?

I get this error usually once during a movie. Sometimes it is 10 minutes into it, sometimes it is an hour, and the only thing I have ever been able to do to get it to work, is to unplug the black power cord from the unit, for 20 seconds, and then reconnect it, and it usually works for the remainder of the movie. Would like to see a better fix, however!!

The F61 fault means the fan needs to be replaced. My system had the same problem and the fan was making a terrible noise. I had this repaired and the system is as good as new. Although I have the SA-HT995 system, it sounds like the same fault.
Still under warranty? Get it fixed for free....
