Get the Service Manual and get out all your test equipment and start checking ICs, Capacitors, Triacs, Diodes and Resisters. Then replace the faulty parts. Or take it to a Panasonic Service Centre.

If no battery door on this it is likely snapped together(the whole unit).You should notice a seam all around the side and it would be in the middle of the side, careful prying may allow you to open it in two pieces where you would be able to see the batteries.

Hi, I have the same issue ! ... Can you let me know if you fixed it please.Regards Brad

Hello Hendrix, I pass the list of reasons why your Panasonic SA-MAX5000 tells you F61, this information is taken from The Community ELECTRONICOS.com F61 The DC DECT circuit of the "micro" detected an anomaly. * See: Note 1 Source: www.comunidadelectronicos.com * Note 1: The error code F61 is one of the most frequent and its origin can be due to different causes. This occurs when the "micro" (IC system control) detects a variation in the reference voltage of the pin called DCDET. This voltage is 5 V. Through this pin (in some models are two: DCDET1 and DCDET2), the micro monitor the presence of DC voltage (direct current) in the speaker output, in addition to the voltages (+ and - ) power supply of the output stage and the other voltages provided by the source (5, 9, 15V, etc.) A short circuit or excessive consumption at any stage of the equipment, resulting in the absence or fall below the normal value, of any of the voltages of the source will cause the reference voltage of the DCDET pin to drop below 5V, causing the micro to turn off the equipment and present the F61 code on the display. The same happens if there is a direct voltage (DC) in any of the outputs to the loudspeakers, of the power stage. In most of the cases that the error code F61 is presented, it is usually due to problems in the power stage. For this reason, it is advisable, as a first step, to check this stage, completely disconnecting the integrated output circuit and testing the equipment again. If you turn on normally, without presenting the error code, it is necessary to replace the integrated one. If after disconnecting the power integrated, still continues to present the code F61, it is necessary to start the checks on the pin or DCDET pins of the "micro" and trace the cause from there. The same could be due to some defective component in the same DCDET circuit, or, because any of the supply voltages is absent or below normal. Not detailed here, specific data on identification of components or voltages of the circuits, because these vary depending on the model. But in all cases the reference voltage in DCDET is 5V The DCDET pins of the "Micro", vary according to the model, for example: in models SA-AK15, SA-AK18, SC-AK27 (and others) pin 32 in models SC-AK22 / 33/44/55 (and others) pins 33 and 34 If it is determined that error F61 is due to any of the voltages absent or below normal, obviously the cause in the corresponding circuits. In summary: A fault in the output stage or any of the power circuits, including voltage regulators, diodes, capacitors, etc., may cause the F61 error code to appear. A "locked" mechanism can cause the consumption of a motor to be excessive, reducing the corresponding voltage due to the overload and also producing the indicated code. As indicated above, the causes can be diverse, but starting the search, from the pin or DCDET pins of the micro with the help of the diagram, you can locate the source of the problem, in order to solve it. Source: www.comunidadelectronicos.com I hope it will help you find the solution Greetings Franco Dosil Hola Hendrix, te paso el listado de motivos por el cual tu Panasonic SA-MAX5000 te indica F61, esta informacion la tome de La Comunidad ELECTRONICOS.com F61 El circuito DC DECT del "micro" a detectado una anomal?a. * Ver: Nota 1 Fuente: www.comunidadelectronicos.com * Nota 1: El c?digo de error F61, es uno de los que suele presentarse con mayor frecuencia y su origen puede deberse a diferentes causas. Esto ocurre, cuando el "micro" (IC system control) detecta una variaci?n en el voltaje de referencia del pin denominado DCDET. Dicho voltaje es de 5 V. A trav?s de ese pin (en algunos modelos son dos: DCDET1 y DCDET2), el micro monitorea la presencia de tensi?n DC (corriente continua) en la salida de altavoces, adem?s de los voltajes (+ y -) de alimentaci?n de la etapa de salida y los dem?s voltajes proporcionados por la fuente (5, 9, 15V, etc.) Un cortocircuito o consumo excesivo en cualquier etapa del equipo, que produzca la ausencia o ca?da por debajo del valor normal, de alguno de los voltajes de la fuente, har? que el voltaje de referencia del pin DCDET baje por debajo de los 5V, haciendo que el micro apague el equipo y presente el c?digo F61 en el display. Lo mismo ocurre si existe tensi?n continua (DC) en alguna de las salidas a los altavoces, de la etapa de potencia. En la mayor?a de los casos que se presenta el c?digo de error F61, suele deberse a problemas en la etapa de potencia. Por ello, es recomendable, como primer paso comprobar esta etapa, desconectando totalmente el circuito integrado de salida y probando nuevamente el equipo. Si enciende normalmente, sin presentar el c?digo de error, es necesario reemplazar el integrado. Si despu?s de desconectar el integrado de potencia, aun continua presentando el c?digo F61, es necesario comenzar las comprobaciones en el pin o pines DCDET del "micro" y rastrear desde all? la causa. La misma podr?a deberse a alg?n componente defectuoso en el mismo circuito DCDET, o, a que alguno de los voltajes de alimentaci?n est? ausente o por debajo de lo normal. No se detallan aqu?, datos concretos sobre identificaci?n de componentes o voltajes de los circuitos, debido a que estos var?an dependiendo del modelo. Pero en todos los casos el voltaje de referencia en DCDET es 5V Los pines DCDET del "Micro", var?an seg?n el modelo, por ejemplo: en los modelos SA-AK15, SA-AK18, SC-AK27 (y otros) pin 32 en los modelos SC-AK22 / 33 / 44 / 55 (y otros) los pines 33 y 34 Si se determina que el error F61 se debe a alguno de los voltajes ausente o por debajo de lo normal, obviamente habr? que rastrear la causa en los circuitos correspondientes. Resumiendo: Una falla en la etapa de salida o cualquiera de los circuitos de alimentaci?n, incluyendo reguladores de voltaje, diodos, condensadores, etc., puede ocasionar que aparezca el c?digo de error F61. Un mecanismo "trancado" puede originar que el consumo de un motor sea excesivo, reduciendo el voltaje correspondiente debido a la sobrecarga y produciendo tambi?n el c?digo indicado. Como se indico anteriormente, las causas pueden ser diversas, pero comenzando la b?squeda, desde el pin o pines DCDET del micro con la ayuda del diagrama, se puede localizar el origen del problema, para as? solucionarlo.

Hi, I have an SAAK410 and also a SAAK510. Both of them would restart after about 20 seconds untill I set the clock using the hand control. Both switch off correctly now. Hope this helps.

Maybe needs some cleaning and lubrication? Seems like sensing some resistance and keep staying on disc 1. Open housing and check what is happening when trying switch discs. Is that happening even when discs are not installed?

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

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: https://shop.panasonic.com/support-only/SC-AK57.html . The current link to the manual is ftp://ftp.panasonic.com/audio/om/sc-ak57_en_om.pdf . See page 7 for the speaker wiring. I hope this helps. Cindy Wells

have a look for all swollen caps and replace as needed for a start

Replace the laser assembly.

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.

You will have to disassemble the unit to gain access for removal.
