It always appears on the OSD na may latest firmware, and na-curious ako kung ano meron sa latest update I checked on Yamaha Aventage support site and found out firmware update version 1.60 lang ang nirelease nila and it was 11/21/2014 pa, I have no idea what is new with the new firmware so I go ahead with the upgrade and successful naman cya, wala naman nabago but I think it has something to do with Yamaha's MusicCast feature... and the next day when I turned on the unit [Internal Error] na lumabas sa display.
What I did was unplugged all connections, pero same result. I tried downloading the previous firmware version 1.60 and execute USB update (PureDirect+Power button), it verified the firmware version 1.60...
but in the end another error appeared. [ERROR! 4000]
Since the unit was bought from the US so NO more warranty. I searched the internet regarding this error and found this german website:
http://dsrocker.bplaced.net/internal-error-yamaha-rx-v671-rx-v673-fix/and thought same series naman sila so there will be a chance na same board din ginamit ni Yamaha and referred to schematic diagram which is BOTTOM VIEW of the Circuit Board:
Found IC89 and just followed the steps according to the website and looked for the component pad to be solder bridged.
plugged the unit and it displays [No Model Info]. Looks like the latest firmware didn't recognized the model info of the unit.
I pressed Scene button "TV" until [*RX-A810] appears and pressed STRAIGHT button to confirm and the "*" disappears.
Power off, unplug and removed the solder bridge.
Plug it in and it runs normal again! Just like no error happened. The firmware was reset to Version 1.60 again.
New firmware update notifies me again but I think I will not upgrade to the new firmware until it has been published in Yamaha Aventage support site.
