"Internal error" My Yamaha Receiver is displaying "Internal Error" message and not getting switch ON. All connection are OK to my knowledge. What may be the probable cause of the error.

Probably in safe mode due to a power supply/output stage fault.

- Firmware update doesn't start or doesn't complete
? Receiver doesn't power up after the update.
? Error message appeared when confirming the firmware version.
Recovery method using USB method:
1. Unplug the AC power cable from wall outlet.
2. Insert the USB thumb drive which has the firmware data stored inside, into the USB port located on the front panel.
3. Press and hold the INFO key and keep it pressed while you plug the AC power cable back into the wall outlet again.
" USB UPDATE " will appear on the front display. Then, release the INFO key.
4. The update will start automatically.
5. When " UPDATE SUCCESS " appears on the display, firmware update is completed.
Power off the receiver and remove the USB thumb drive.
6. Confirm updated firmware version.

- Error message appeared during the update
Cause: For some reason, the receiver can't read the firmware data.
Method: For your solution, check the following
[Update through Internet]
? Check Internet connection.
Check if the Internet connection is working by playing an Internet radio station.
(See owner's manual for details)
[Update by USB thumb drive]
? USB thumb drive is connected properly to the receiver.
? USB thumb drive is not password protected.
(AV receiver cannot read data from a security protected USB thumb drive)
? Make sure the USB thumb drive is inserted before the receiver is powered on for the update.
? The firmware data is stored in the root directory of the USB thumb drive.
? There is no other data except the firmware data in the USB thumb drive.
? No folders are created in the USB thumb drive.
Else, retry the update by USB using another USB thumb drive.

Need to take it in and have a tech reset the region. Somehow it got erased.

I had the same problem (though the unit may still work even in this Internal error state, except the tuner - try it) and my technician friend advised me to replace the HDMI I/O Card inside the unit. However the card cost is more than a hundred dollars while another brand new unit only costs around USD170 in ebay. That gave me a better option to buy a new unit but seems this Yamaha unit is a dud which could be the reason the unit production was discontinued.

Hi.

The receiver is in forced standby because an internal error has been detected. The condition occurs when there is an internal failure, a wiring related problem (e.g. bad cable), or a wrong voltage from power source is detected (e.g. power surge).

At user level troubleshooting consists in disconnecting power cord, waiting ten or twenty minutes and connecting back (power reset), or in checking cables connected to the unit, replacing cables and restarting the receiver with no cable connected.

If that does not help, then there is an internal failure.

In that case contact Yamaha at the number listed in the owners manual.

Hi there,

It simply means to check your (sp)eaker cables. It is likely that one of your speaker cables is damaged or not correctly connected. This is causing an overload in the receiver and the cut-out indicates the receiver has gone into 'self-protect' mode, to prevent damage to the internal components.

This could happen if you have cross-wired + and - to one or more of the speakers. It could also be that a cable to one of the speakers has been partially severed and +/- are shorted together or it could be as simple as one of the speaker connections having become detached. Speaker connections are polarised positive + and negative - the same as your household electrics and need to be wired to the correct poles.

To fix this problem, you should initially check all of the speaker connections at both the receiver and speaker ends. Make sure everything is properly connected and that + and - on the receiver are correctly wired to + and - on all speakers. If all of the connections are correct and the error message persists, disconnect each speaker one at a time, reset the receiver and test again.

If you disconnect a particular speaker and the error message no longer appears, you have found the cause of the problem. Examine the cable for any sign of damage and replace the cable. If there is no visible damage, it is still advisable to replace the cable for this speaker as damaged cables are not always visible to the eye.

Please check all of your speakers as above, then let me know if you need further assistance. The message could be erroneous and may indicate a fault with the receiver.

Hope this helps.

Regards,
BElectric.

Unhook all HDMI connections unplug the yamaha and your tv from the wall outlet then try again. Most cases a copy protection kicked in or the hdmi had a error on the port, Worse case is hdmi controller board failure in ether the TV or the yamaha.

thanks and do be considerate and leave postive feedback and ratings for those that have helped you today, Thanks

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

HDCP is copyright protection for HDMI ensuring that you can't copy the protected material.
Did you connect some new DVD player or new TV to the receiver? However the error should clear once you disconnect everything from HDMI. If not, try to restore the receiver to factory defaults.

found the source of the problem with "Check SP Wires"! to solve it is necessary to check each speaker connected to the device Yamaha on the rear panel (red and black) using the device for determining the number of ohms, which shall not be less than 4 ohms, in large passive speakers experienced in Amfitone AU-027, the result showed that left at 0.45 (7) ohms, and the right-hand column, as such, no.
The successful test ... and good music!
