When I turn on the radio or insert a CD almost immediately stereo turns itself off and message F-61 appears. It has worked fine for past 2-3 years. Model SA AK640 panasonic stereo system

ITS CHEAPER TO REPLACE THAN TO REPAIR

Very complex problem, could be your steering wheel controls, ECM sending false digital signals or just a bad radio (internal contacts bad) or maybe someone (a child usually) has inserted a penny or such into the disc opening. Yes it has happened before. Replacing the stereo with an aftermarket unit might be the best bet on pricing. Good Luck!

some electronic service is required

you need a replacement laser

You need to reset the system, disconnect the car battery for 10minutes....... reconnect, enter radio code and should be back to normal.

Is this a factory stereo.......what barnd is it, and when is it turning itself on

That sounds like your radio is going into protection mode. I would disconnect your speakers one at a time and see if your sound comes back on.

Please try this!!
You may need a soft or hard reset. Here's some reading and instructions.
Please use this first!
resetting your scanner
1. Turn off your scanner, and then turn it on again.

2. Insert a pointed object into the reset hole on the back
of the scanner. Then, gently press and release the reset
button. Pressing reset does not clear the scanner's
working memory or the V-Scanner folders.

If this doesn't work here's step two! CAUTION. THIS WILL ERASE EVERYTHING, but it MAY Fix the Problem!!

Initializing your scanner clears all information stored in your
scanner's working memory. Initialize your scanner only when
you are sure it is not working properly. V-Scanner memory is
not affected when you initialize the scanner.

1. Turn off the scanner, and turn it on again. First, the DSP
boot version, and then Welcome To Digital Trunking appears.

2. Press 0. The following messages appear on the display:

System Tests

Select Test
Exits if no
Key Press

3. Press 1. The following messages appear on the display:

Factory Init
Erase Memory
ENTER if Yes
CL to EXIT

4. Press ENT. The following messages appear on the display:

Initializing
Clr Main Mem
V-Scan is OK
Please Wait

5. Do not turn off your scanner until the initialization is
complete. When the initialization is complete, M000 and
Bank 0 Ch 00 appear on the display.

Hope this works.. Happy Scanning

clean the radio with a cd cleaner if dosent work replace radio call me for an estimat at 520-882-8979 most of the factory radios only work for 3 years

try to leave a CD inserted on the CD tray to avoid the undesired "auto" turn on

sounds like a short or loosening wire somewhere - have any "after- market" accessories been added ??? new stereo or amp ?? check these item and there wiring if so. It could also be the ignition switch itself......unfortunately - you may have to wait for a permanent failure to find the cause
