Question about Panasonic SC-HT70 System

3 Answers

Turns off My Panasonic SC-HT70 system is turning itself off. When it turns off an error code comes up F61. The manual states that a speaker wire could have shorted but have checked that and everything is fine. In fact when I first turn it on everything works, including all speakers. Then it just cuts off. Any ideas?

    My Panasonic SC-HT70 keeps swiching off displaying code F61 indicating that the speaker wires may be shorted. The speaker wires are not shorted. I think the first swich off was when the volume was very loud as though it was some kind of overload protection.

    Mine too. Turns off with a loud bang and f61 flashes on the display. Is this a sign of future problems?

    I have the same problem. Switches off with a loud bang and f61 on the display. Is this a sign of future expensive problems?

My system does the same thing with F61 displaying for 5 seconds before shutting off. I took the fan in the rear off, and noticed that it came on to the touch but didnt stay on continuously. However, when it came on It started performing normally. So, I also noticed that the insides where the fan was located became warm when no air was blowing on it. System will shut off to protect itself. Dont know how to get fan off yet. But fan for my model is sold on Panosonic Website. Not very expensive if you know how to install. Around $17.00 for fan itself. If someone knows how to install , please send message.

I've fixed many of these, almost always needs the output ic RNS-704D-65. ( I think that's the part #) not cheap! Before taking it to repair disconnect all the speakers and turn it on If F-61 still comes up it probably needs it.

Panasonis SC HT70 Plays for about 1hour then comes up with F61 Fault code


This fault code means the speaker cables may have shorted, or the speakers are not the correct resistance (ohms) Are you using the speakers that came with the unit? If not, make sure the ohms rating of the speakers you are using are the same as the factory speakers. If they are the same, the unit may just be overheating, make sure it is in a well ventilated area, and dust-free.

Unit says error F61 then rings and shuts off ...


F61 usually means the amp has detected a short or a severe microprocessor error.


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Turn on dvd panasonic sc-ht440 the display see me f61


Hi, F61 is and amp error code. probably needs an output ic. could be a shorted speaker or bad cooling fan. Disconnect all speakers and turn it on. if the fans run and it still displays f61 then odds are very good an amp ic is bad.'''Hope it helped.

Have a nice day..

When turning on F61 shows on the display and will not turn on


People say that it is a fan problem - when it gets stuck with dust or does not work properly the system recognizes it and gets blocked in order to prevent overheating of the components. I changed the fan but the problem with F61 presists despite people say that changing the fan would solve the problem.

F 61 Code


The if the "bad sound" is coming from the speaker(s) it probably needs the output ic. If it is coming from the player itself check that the fans are working. F61 is an amp error code but a non-rotating or unplugged fan will also set it off.

SC-BT 100 Error Code f61


Had the same problem. Found that the code refers to the cooling fan. Could be that the fan is dusty or not running when the system starts up. I removed the fan with the two screws and reseated the plug. Make certain that the short, black wire (that seems to go to nothing) is securing the plug to the board.

Panasonic Dvd Home Sound system SC-PT950 code f61


The F61 is the coded "protect mode" indication. The internal amp chip has failed. It sounds like this system should still be under warranty. Return it for warranty service. The amp chip will be replaced.

Sorry about hte delayed response. I was away in business for a few days.
