After turning on Panasonic SA-HT 990 appears F61 on display and receiver turns it self 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.

Repeated F61 fault code on Panasonic Home cinema system Model: SC-HT990 Is it the fan in the sub woofer?


Hello

F 61 error means the failure of FAN
most probably dust in the fan made it to stop working so clean the dust and connect the fan to an external supply of 12v(using red and black wire) for 5 minutes and reconnect it to the unit otherwise replace the fan with new one.
Surely this will solve the problem.


Kind regards

F61 error code


Sorry to hear about your error code F61

This code refers to a High Limit Temp. condition.
This is most likely caused by the cooling fan.
If the Fan has stopped running or not running at full speed, you will recv. this error message and the temp. reaches high-end limit.
Please check the cooling fan, any possible air flow restrictions and correct running RPM.

Hope this information has helped you.
Readers, please rate your technicians information.

F61 Error then the system goes dead


The battery might have broken so you might want to try buying a new one or charge it up fully.

The F61 is the shorthand for protect mode. This indicates a problem with the output amplifier section. I don't have a listing for your specific model, but a similar one HT95 lists IC501 as the output amp chip. Check for the marking on the large black IC attached to the heatsink it may be RSN311W. If so, this can be ordered using part number: RSN311W64D-P for $95.20 from tritronicsinc.com.

Hope this helps,
Dan
