Re: SHOW ''F61''

This is error code which system control detected either power irrgularities or dc voltage is detected from the speaker out put line.This fault we have noticed that both of them appears same time also.Pls change Amplifier ic TDA8920 and C1740 transistor and 27V1w zener diode.Transistor and zener diode is for voltage regulation and amp ic if the dc detect is active.Usualy change this three components same time.(this all is in power amp section)

My panasonic stereo system sa-ak300 has not been responding correctly when i turn it on. When i push the on button it shows F61 on the display and goes automatically off. Whats the problem? What do i have...

Have you looked at the manual?

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 '*****'. 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 another possible root cause for intermittent shutdown.

I suggest you Google Panasonic on your computer and pose your problem to them. They will tell you what the code means and what needs to be done about it to make the stereo work properly.

Press power it shows f61 instead of what it should show

You need to open the back of the system and change the fuse located on the right side of he panel. you can go to Radio Shack and get the fuse for $1.99.
