    Same problem on Panasonic SA-AK78, changed the output IC501 and still F61 is there. I bought the electronic layout schematic, there is a small variation between the circuit I have and the one showed on the schematic.



    So I am still investigating this problem.

    And if the fan does not turn on power up??

    Power supply voltage flow is hard to follow as it goes to 3 PC board for either validation or then voltage reduction or regulation.

Check that the fans are working they should start on power up. If they do its probably the output IC. (not cheap around $100) for the part.

Samsung s3 phone wont turn on only red light stays on and a buzzing noise sounds and wont turn on need help


Shut it down by holding the power button until the screen goes black, don't tap the power off button, wait for the black screen. Then let your phone charge for a few hours (maybe over night) with power off and see if that helps.

Try another input and another source such as a DVD player. If you still get the buzzing sound, you could have a faulty power supply output or a fault in the audio circuit of the main board.

Won't turn over... just makes a clicking sound... and a wierd humming sound.


Try cleaning your terminals at the battery, even if not corroded. In my years as an alarm/radio installer I have come across this problem constantly, especially on GM vehicles.

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.

In this case there are two possibilities of what part is the one causing the issue, it coul be a ballast because of the clicking sound that caused the tv to shut off, and that buzzin sound is for your color wheel that it might not be working anymore, discountdashmerchantdotcom free troubleshoot
