When i turn off my Panasonic model sa-ak18, it won't stay off. It shuts off for a short time then it comes on again by itself? How can i repair this?

Presuming that other sources work okay and the the cables are connected correctly.....Try a CD Lens cleaner.

If that doesn't work then it's time to open up the unit and manually clean the laser lens. If that still doesn't work then the laser might be dead. Replacement parts may be available. Whether or not you can do this as a DIY repair though is questionable. It depends on your skill.

Hi there,

If the tv is still under warranty, this can be repaired at no charge.

However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).

The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.

Hope this helps.


Cheers,

Scott

The audio output ic is getting to hot due to bad connections or ic failure. Check the speaker wires for shorts, if okay! semiconductor needs to be replaced.

Hello
Get into this website, from where you can download the user manual of your stereo system in Adobe Acrobat document. If you feel any difficulty in downloading the manual, send your email address to me by FixYa. I've the manual and I'll send a copy of it to you by return mail. OK

F61 usually means the amp has detected a short.

Generally speaking, an amp protects itself from heat, shorts and overloads 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 as a root cause for intermittent shutdown.

F61 is an error code.
It will automatically shuts down your unit.
This is very common on your unit.

Try to checked if the fan is working or not.
I have repaired some unit before, this is the caused why f61 appeared.
The symptom is shutting down the unit after a few minute.
If the fan is not working it will shuts off automatically to avoid further damaged to your output I.C.

If confirmed that the fan is working then I've suspect that your output I.C. is shorted.
This is quit technical and need to send to repair shop to isolate the faulty parts.
The output IC of your unit is RSN series and quite expensive.

Pls rate my help.

Thaks for using fixya...

My stereo turns off and displays F61. How do i fix it.

my CD Stereo System SA-AK18 turns off itself displaying f61 error, what does it means? how can I fix it, plz help me

ic stk 470-040 is blown.this is the most common error.just get it changed

hi the problem your having could be one of a couple of things the first to check is that all the speaker wires a fitted correctly and not come out of socket as a speaker wire shorting could give you the problem your having.
The second and most likely problem is going to be a problem with the amp part of the circuit board usually a blown resistor but in your case as the unit comes on for few minutes then the chances are its just a solder joint failing on the board this causing the unit to trip out as a safety measure to stop it setting on fire.
Check the sub woofer cable is fitted properly as this is the usuall problem with you make and model let me know when you have checked all of this ok
