This is a common error for these Panasonic units. I work at an authorized Panasonic service center and have repaired many of these.

This error is caused by either 1 of these 2 problems, both of which will require service for replacement of parts.

1. The amplifier IC is bad and needs to be replaced.

2. There are a couple of smaller components in the amp circuit that need to be replaced. One is a zener diode and the other is a resistor.

The F61 error is caused by a bad amp circuit or power supply circuit. In most cases it is the amp circuit. More often than not, it is the zener diode and resistor that are bad. This would be preferable since the amplifier IC is very expensive and a total repair cost would be close to $200. The zener diode and resistor repair would be closer to about $100 depending on the rates of the service center.

I know this may not be the answer you were hoping to get, but it is the problem you have.

If you found this information helpful in making a decision on what to do with your stereo a FixYa! rating would be appropriate and very much appreciated, after all, it is the only reward we get for offering free help to people like yourself.

If I can be of any further help just reply to the post and I will get back to you as soon as I am able.

Good luck with your stereo, I hope you found this information to be helpful.

f61 is power supply failure. Time for a repair at an Authorised Panasonic service centre.

I had the same problem - you can fix with a system reset. Unplug the unit at the wall and wait 2-3 mins, then plug in and switch on while holding the power button - the display will be blank for at first, but will eventually display '---------------------'. Release the power button and switch the unit on as normal. Press the Dab button and the unit will start to auto-search for channels. Give it a few minutes and you'll be back in action :)

Cannot eject disc. ≥The unit may have a problem. While the unit is off, press and hold (>> / >>I) and (< OPEN/CLOSE) on the main unit at the same time for about 5 seconds. Remove the disc . After disc removal or if this does not work you may need to reset to factory defaults. for the player alone.

To return all settings other than some settings to the factory preset.

≥Select “Yes” in “Restore Default Settings” in the Setup menu.

This returns all values in the Setup menu and the on-screen menu, except for “Remote Control Code”, “On-screen Language”, “IP Address/DNS Settings”, “Proxy Server Settings”, “Network Service”, “DVD-Video Ratings” and

“BD-Video Ratings” to the default settings.

If this does not work then you may need to reset everything to the factory settings.

To return to the factory preset. Everything Reset.
(No setting)

≥Reset the unit as follows:

1 Press [POWER] on the unit to turn off the unit.

2 Press and hold (>> / >>I) and press [POWER] and [< OPEN/CLOSE] on the unit at the same time for more than 5 seconds until “PLEASE WAIT” is displayed on the unit.

3 The power is turned on and then turned off automatically.

The SA-AK57 is the center of the SC-AK57 mini stereo home theater system. The included speakers have color coded wiring for the front speakers. One speaker connects to the red and black terminals on the SA-AK57; the other speaker connects to the blue and grey terminals. Push on the top of the terminal levers and insert the bare copper wire into the opening. Then release the lever. The center, right and left speakers use a single RCA or banana-plug connection and plug straight into the jacks on the SA-AK57. Panasonic has the manual for the SC-AK57 on the product page: . The current link to the manual is . See page 7 for the speaker wiring. I hope this helps. Cindy Wells

How does it manage without speakers?

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

Generally speaking, an amp protects 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.

Turning a wired speaker into a wireless speaker would be difficult and disproportionately expensive. Each amplifier channel will need a transmitter and each speaker a receiver, a preamplifier and power amplifier and a power source capable of supplying the whole for a reasonable time before recharging. If you choose wireless (radio) to transmit to each speaker the frequencies will have to be adjusted so they don't conflict. If the speakers are to be used within sight of the base then infrared transmitters and receivers could be the answer, similar to that used with some of the early wireless headphones.

1. Open internal fuse 2. Power supply failure

Panasonic Audio... • Answered on Dec 29, 2020

Possibly because components in the amplifier chains have been overstressed and consequently failed. The output stages are frequently affected by high gain levels.
