Have to agree with bestdarngood and Benimur that it is the voltage regulator.

Here is good troubleshooting guide.

May come in handy also if you choose to take it to a service technician.

Hi,

F61 error codes could either be IC501 or the regulator (IC502) in the power supply section.

For reference, pls view these two (2) posts here and here of similar concern on other models.

Other possibilities are:
1. fan not turning;
2. cold solder;
3. looses connections;
4. one of the other components/systems hooked up to the power supply is causing a fault (tuner, disc player).

Hope this be of additional help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: Panasonic SA-PT480 will not turn on after power

it sounds to me like you have endured a power surge and it has cooked the unit // i would replace it as surges do so much damage it normally writes the unit off but your power company is liable to replace it (if it was a surge)

SOURCE: Panasonic SA-HT820V need universal remote that can control radio

I had a similar problem. I disassembled my remote (flat screwdriver and pulling, cleaned the circuit board and rubber buttons thoroughly with rubbing alcohol, then reassembled.
For some reason, the remote didn't work properly until I started pressing the channel buttons immediately followed by the volume buttons. It worked normally, after that. It was most likely due to the not yet dry rubbing alcohol interfering. My remote now works, normally.

My panasonic sa-pt460 surround sound system won't play any new dvds, does not recognise them in the system and says no disc, is this something that can be fixed or just because of the age of the syste


Sounds like it may have a hardware problem, specially if sometimes it plays one disc, and others not (I mean the same disc).

But in any case, check to see if there are any firmware updates from Panasonic, that may fix the not recognising new discs issue.

Usually firmware updates are done by formatting a USB pen with a manufacturer's tool and then booting the unit from that USB.
In some others just leaving the firmware file in the USB, and the unit will pick it up an upgrade.

Do the discs play okay in other dvd players? If not, perhaps the unit is getting hot during recording? Mine has to have ample space around it in order to not mess up.
