@@M-Help Hello my friend, actually I have the exactly same model but I was just doing some research, I am not a tecnitian but I found out the replace part is really expensive here in Venezuela so I've been looking for some alternative, I find brilliant how you solve the problem
@@ramontorres2647 I didn't have a small transistor that controls a large transistor from 47v to 26v and I couldn't get it, so I decided to simplify the whole circuit. Basically these big 47 volts are not needed, if the output part holds only 26 volts max, then I found ~ 15v = + - 20v, 20v is enough.

I ave a panasonic 5 cd changer SA-AK750 .BUT THE PLASTIC THING ON END OF SPEAKER WIRE IS OFF AND I CANT FIND IT OR THE METEL PRONGS INSIDE THE PLASTIC BIT any idea were I can buy one I've tried every were u think.👍
All Panasonic have similar problems and usually difficult to solve problems. But there are simple ways to solve it. So you have problems with the speaker outputs? Solution: Whether the output bay is dead, or the mouth of the output is turned on without a user, or no power is applied to the output chip, there may be a power supply problem or the preamp power sound may not reach the output chip. Tell us more about the problem?⚙💯✔
Be careful when measuring volts with Digital Multimeters, because there are -47volts before the transistors and +47volts = + -94volts in total. For the output itself -26v and + 26v = 52volts.⚠⚙⚡🔥
mine turns power on.then wen I press play on cd or tape or anything it goes straight to F61 and I looked in my manual and it says it's about speakers and I know I only got 1 plugged in cos I've lost the other end for other speaker
@@Kare122 Disconnect the Speaker from the device, may display F61 error resistance due to changes in the speaker, or the speaker is short and the device turns on the protection.
Hello, I have one of the exact same model with the F61 problem, as soon as I turn it on it goes straight to the error. in the video images I've already modified the power supply and cooler, but I don't understand the first photo, do I just have to remove the 3 transistors or is there something else that needs to be done?
The large 2 transistors must be removed and 2 transistors soldered on the board, the incoming T1 -47v and T2 + 47v with the output current were T1 -27v and T2 + 27v. The small transistor is responsible for 27v. The large 2 transistors are soldered out and inverted with their feet in the air and screwed to the housing so that they do not disappear. How much do you understand what you are doing or have any experience in repairs? Be careful doing this!
I'm a hardware technician, but I don't work with stereos. I got this one as a gift and I wanted to try to bring it back to life. your video is the only one that has a way to circumvent the F61 error, but this part of the transistors left me in confusion, I really wanted to know if I have to make a jump in the circuit where the transistors are removed.
@@frankdragon1 I have 15 years of experience repairing car radios and car amplifiers, all kinds of devices. You had measured the current from the large transistors, if there were T1 -27v and T2 + 27v, then you could convert these currents. If it is transformed as I have to solder out the large transistors and have to solder the TF1 -20v and TF1 + 20v coming from the transformer with TF1 -20v -> T1 -27v and T2 + 27v -> TF1 + 20v, two contacts together.
@@M-Help Hello again, sorry for the delay, many services pending. The problem I had was some Zener diodes that were leaking and the negative output of the power supply was without signal, I changed the zeners and 1 fuse of the negative signal of the power supply and it came back to life. Thank you for the inspiration in repairing this device.
I have this same problem and I don't understand anything about electric components (Except computers). So you recommend in this video get out that transistors and that is all? My Panasonic ak-250 put error f61 when I rise the volume to 20. Greetings from Mendoza, Argentina and sorry for my bad english.
In my video there are problems 1. power supply where there is too much volts, but there must be 26 volts on both poles + 26v and -26v, if there is no 26v met f61, 47 volts must not be on the output will not work f61, 2nd fan power supply, disconnects to avoid error f61.
You have a problem: a fan that doesn't turn at 20 volumes. 1.Power supply to fan or 2.fan broken f61 and replace with new fan or 3.mini transistor must be disconnected or blown out f61. 3. both speakers are not on the short f61. 5. The output part is short, then a new output part (chip) must be replaced.
@-M- My fan turns on 21/22 volume. So the fan works well. When I rise the volume to that values comes f61. The exact moment when the fan turns is the moment when f61 appears.
Hi i got a panasonic sa ak250 from my friend but it is not working. There is no sound even after I have connected the speakers to the channels. What could be the cause?
Maybe there are various reasons for no sound: 1.speakers damaged, 2. output chip damaged, 3.fan damaged, 4.volume button damaged or dried out grease for volume button, 5.conistor and diode 26volt circuit defective, 6.may not have contact on board solder joints may have micro cracks.
The part of the output chip of the speakers is probably not working, check it, if it is burnt and there is a short, then you need to change a new one, most likely the error was caused by the part of the output chip, it usually shows an error if the output part is damaged. The error can be displayed for several reasons.
Thank you very much for your time and advise!
Helped you solve f61? Do you have this Panasonic?
