Check hori output and small blue high voltage capacitor 2k that feeds hori output transistor.
If these componets are OK then replace Both of the STK ICs they are big black ICs and will have PN# on them.example STK392-110.

What does f61 mean?


F61 is an error code.
It will automatically shuts down your unit.
This is very common on your unit.

Try to checked if the fan is working or not.
I have repaired some unit before, this is the caused why f61 appeared.
The symptom is shutting down the unit after a few minute.
If the fan is not working it will shuts off automatically to avoid further damaged to your output I.C.

If confirmed that the fan is working then I've suspect that your output I.C. is shorted.
This is quit technical and need to send to repair shop to isolate the faulty parts.
The output IC of your unit is RSN series and quite expensive.

Pls rate my help.

Thaks for using fixya...

Hi,
f61 is a protection code. it 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.

F61 error message


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
