Tip for everyone wanting to solve any modern electronics problem. 1st I check for obvious damaged parts, like resistors heat damaged (cooked) and electrolytic (polarized) can capacitors that are bad or getting bad - look at the top of all biggest ones to see if it is swelling and top is bulged up. Any bulging means it needs replaced. 2nd thing i always check is if there is any bad (cold) solder connections on the PCB's. Use some head worn magnifiers and inspect all ribon wire connectors, and all wire thru hole connectors that have a component that has a lot of mass to it. Large parts will cool solder down too fast when the device was manufactured and cause it to be a "Cold" joint to often. It might pass testing, but vibrations and heating and cooling cycles can make these weak connections eventually fail. Look for hair line cracks around the parts leg poking thru the hole. If any connection doesn't look like the good ones, it is suspect and should be resoldered. 90% of all repairs i do is finding and resoldering bad connections on modern consumer electronics. The lead (pb) free solder used now in manufacturing suffers greatly from doing this. I use 60/40 solder to make the repairs by heating the connections and adding solder to make sure it is a "wet" connection. Be sure to not make any solder bridges to a nearby connection or known as a "Short circuit". A great additional soldering aid tool is a solder sucker for removing excess solder or to remove a part and clear the hole of solder so replacement part can be mounted as original part was. Every solder connection must meet 2 conditions in order to be a proper good joint: 1 it must provide the best possible electrical connection between components that can handle The current flow. 2 it must provide structural support for the component to prevent the solder from failing due to mechanical stress. If you make all connections meet these 2 requirements, you have performed the work correctly. After doing this inspection and working on suspected connections, then test the device to see if problem is solved. If problem persist, then do like this guy did and check for proper voltages from the power regulators. Some devices have multiple voltages they use, some only have one or two. NOTE: Always disconnect power from device before attempting to do any soldering. Never solder live circuits! Only use soldering irons, preferably a DC isolated one for sensitive electronics. NEVER use a Soldering Gun on low voltage circuit boards! Guns are a inductive method to heat the tip. There can be a high current flowing thru the soldering tip that can destroy sensitive semiconductors on low voltage circuit boards. Hope this helps everyone and good luck. Thanks for this video sir, it is a very good informative example of troubleshooting a device and repair solution. I have the same stereo to fix for a friend with same error code.
Muito bom a sua explicação, vc esta de parabéns, é desse grande técnico que precisamos pois passa o ensino. Aqui no Brasil tem uns que guarda o que aprendeu. Abs e muito obrigado.
Thanks for the information,, please my own Panasonic it will on standby but, when I click it,it will dim 🔅 and the replay will click but not display anything in timer and it will go back to full timer
If I remove cassette player and DVD player then only audio amplifier will work? I mean can I play the set without cassette and DVD player? I have (sa ak 85)
@@glenntips thank you so much. But after removing my cassette and DVD player then my set get power but when I press AUX or another buttons then my set get F61. But it was working once after removing cassette and DVD. But after that it is standing on f61 till now. So I was confuse.
@@binodon-hub2685 maybe there is another problem, also sometimes when the blower wont connect there is f61, also try to look at the amplifier section or the relay maybe there is a loss connections
I have a Panasonic sa vk760d As i turn on the system and play something,after sometime it freezes ,nothing changes and when i turn of from socket it makes a thud noise
Hello sir my panasonic sa-dk20 show f61 error before f61 the only subwoofer and center speakers work and rsn311w64 is very heat up and fan isn't working and one day when i power the music system its show f61 error i think the rsn311w64 ic is damaged? plzz tell me i am correct
Sir when i power the system it show f61 error but the power amplifier ic isn't heat up it cool down before f61 error the only 2 channel work and rsn311w64 is very heat up
Sometimes if the cooling fan doesn't work, it makes an error f61,check the input signal in front speaker and make sure if there is no loss contacts, also check the fan if its broken. If not, trace it if were is connected
@@glenntips sir before showing error f61 the cooling fan isn't working i checked the cooling fan separately but it work and then i put it again it doesn't work i 100% sure the rsn311w64 is damage i order rsn311w64
Yah mujhe speaker banvana hai Panasonic uski picture to maine aapko send kar sakta hun aur banvana hai aap banaa dete to aapki meherbani Hogi is chij mere pass padi Hui hai
