Bar 48 fail to power on after firmware update

Recommended Posts

Hi, my Klipsch Bar 48 fail to power on after the new firmware update. Totally no power even after changing power cable and wall socket.
I am trying to update it with the new firmware following to the instruction provided, there were no response when I plug in the USB, hold the power button while connection the power cable. Afterwhich, the sounder fails to power up. Does anyone having the same issue?

Yes, I had the same issue (search past threads). The only way I could restore function to the BAR 48 was to load the previous revision of firmware's batch file (one that works) onto the USB drive and reload. It reloaded w/o any issues and got me back to where I was before the "latest" firmware locked it up. Important: Please double check you uploaded the correct firmware version for your specific serial number. *This is a known issue.

Many thanks for the information. Unfortunately I don't have the previous firmware revision anymore and also could not find anywhere where I can download. 
Do you happen to have a copy which I can get from you?

Looks like Klipsch realise the problem, there is an updated firmware available for download. I have downloaded it and manage to update with this version and the Soundbar is back alive again.

@CKLIM After reading your post I checked for a newer version of the firmware. The latest one was Released: 12/13/2019.

 

What version did you download the first time? Is it possible you entered an incorrect serial number and download firmware that wasn't valid for your device?

In fact, Klipsch does appear to finally have read their email and realized that they uploaded one or more defective firmware files. The one that I had trouble with was only 1/3 the file size it was suppose to be and locked up my system (IOW: they forgot to add all of the data to it) and has since been removed by them. They uploaded a new firmware file dated Nov 29th to replace it which has the correct file size to imply it is complete (though that does not mean it will work). If you did input the correct serial number and had a failure with the 12/13 dated defective firmware file, it is worth deleting that file and downloading and installing the new replacement file, backdated to November. Note: this only applies to you if you had one of the defective firmware files. Some of the units use an updated firmware file which is also dated Dec 13th which is NOT effected by this. These files are serial number dependent. If in doubt, re-check the support site's firmware download page to see which file they are currently showing for YOUR system. It may or may not have changed. Maybe that will fix some of the issues many of us are having ???

 

In the meantime, I received my replacement BAR 48 with the 2.4GHz wireless connection and will certainly have to install the appropriate newly updated firmware on it when I get home to see if that one works and solves the un-plug/re-plug issue with the wireless sub woofer pairing lost.

DaleG: Yes, for your s/n range, no change was made. For some others, a change was made and new firmware is now available.

Note: The change logs are all the same and unchanged. They did not update those.

Just yesterday, there is a new firmware update procedure posted on the klipsch/firmware page. I followed it with no problems.
