F61 IS THE ERROR CODE FOR A FAULT IN THE
AMPLIFIER STAGE OF THE UNIT, if the power fan or supply is okay then THE MOST LIKELY CULPRIT IS THE AUDIO
OUTPUT IC, WHICH IS A MULTI LEGGED DEVICE SCREWED TO A PIECE OF METAL
USED TO COOL IT, IN PANASONICS ITS PREFIX WILL PROBABLY BE "RSN" BUT IT
COULD BE "STK", MAKE A NOTE OF THE NUMBER AND SEARCH ON LINE, DONT
FORGET TO CLEAN OFF THE OLD HEATSINK COMPOUND ON THE HEATSINK AND
REPLACE WITH FRESH.f61 means theres is a
fault with audio output ic, usually there is dc on one of the speaker
output rails, replacing the audio output ic will usually cure this but
check speakers and leads for shorts before reconnecting to the unit
The F61 indicates a problem detected in the output amp stage and the unit us shutdown to prevent further damage. If you can supply the model number, I can give you the part required and the approximate cost.
The F61 indicates protect mode. There is a problem with the output stage of the amplifier section and the unit shuts down to prevent further damage. This unit will require service of the amp section. You can try to contact Panasonic for the service manual.
The output amp pac is an RSN311W64D at a cost of $95 plus shipping.
Several components in the power supply maybe faulty, especially Tranisitor Q5110, Resistor R5114 and Diode D5102 on the power supply board. Check and replace these and also resolder the regulator IC's on the heatsink.
Sound amplifier ic??******** this guy is talking out of his ***. F61 relates to fan error. There are two fans, one of them is either spinning too slowly or not at all. This fan can be purchased in any computer store. Just remove it and take it with you.
