Hi guys 

have some concerns regarding the TS8

sometimes when I power it up I’m getting a blank screen ,AKA - zero / nothing 

this can be “rectified” by turning the unit off ,on 

but sometimes it takes a few goes 

it’s basically proving to be a little unreliable 

any thoughts / ideas?

obviously if I can’t get around this I’ll be returning the unit - which I hope not to 

cheers & thanks

Thanks for your reply

power supply in properly was not an issue - you could see the unit had powered on from the screen but the screen itself was blank of any information

after reading a review by Craig Anderton - where it was mentioned people were saying the TS8 was unreliable but CA thought it was because they didnt have the latest firmware - I found your page/videos of how to update - and haven't had an issue powering up since - so fingers crossed it was a firmware issue 

I only had the unit a little over a week 

thanks again


I have only had the T8S a couple weeks and I have done the firmware update and I'm still having problems when I start up the mixer.  Today at a show it took 8 try's before it finally came up, talk about nervous because I actually took my old Tonematch out of our gig bag this morning... I really have concerns with this issue.  I gig 5 days a week and I really need to know my equipment is going to work.  Yep the old T4 is back in the bag.  Please advise Bose if you can , I'm starting to think I must have a lemon.  Too much money for these results.

Thank you,



Hi Mary,

Welcome to the Bose Portable PA Community.

I'm sorry you've got this issue (blank screen) with the T8S.

Are you using the ToneMatch power supply that came with the T8S? If you are then please call Bose Support and they will take care of you.

If you are connecting the T8S to an L1 Power Stand using the ToneMatch cable (from the T4S), please don't do that. The L1 Power Stand cannot supply enough power to run the T8S.  Always use the ToneMatch power supply that came with the T8S.


Thank you for your reply.  Yes I am using the tonematch power supply that came with the T8S.  I learned that lesson quickly when I was using it for the first time at a wedding reception, yikes! I will be calling in for bose support.

Thank you,
