Helix No-Boot w/ ":-28" Problem

Recommended Posts

Hi everyone,

 

I just got my helix (second hand, like new)

Most of the time, no problems and I'm also very satisfied with my tone so far. But sometimes it just won't boot.

The boot screen acts normal, with the moving spirals etc., but it doesn't disappear and the home screen doesn't come.

Added to that, the top left of the display reads ":-28" in red characters. (See the Image attached)

 

I believe I saw this happen with FW 2.10 which was loaded when I bought it. Now I'm on 2.12 and I still have it.

 

Anyone else having this?

I mean it's no big deal as it's not happening all the time, but if it's a sign of something important, I should solve this problem right?

 

Thanks

Personally not seen that glitch before, but from you post I guess this is an intermittent problem?

 

With something like this the usual suggestions would be to re-flash the firmware and reset the globals.

 

This may seem obvious but have you run through all various reset options using the foot switches?

 

If not give them a try.

Hope this helps, good luck.

I have a new Helix Floor, with v2.210, and I've experienced the same thing (frozen boot with the -28 code on the screen. I has now happened twice (at gigs!). Each time, I turned it back off and back on again, and it came up normally, but I'm concerned.

 

Would like to know what's wrong.

 

Thanks

Mine freezes on startup quite a bit, not noticed the -28. I will look closer next time.

If I were you guys I'd give the tech support folks at Line 6 a quick call.  Phone support is free and if this is known prevalent problem they probably know what causes it and what it takes to fix it.

Mine freezes on startup a little bit. Maybe twice in the last 6 months. Turning it on and off fixes it. But it does worry me a little.

I had this problem when I first tried to update to 2.0. I never received a satisfactory response other than it was a significant error message. Ultimately I had to send the Helix back to Line 6 and they replaced the motherboard. I think a power surge at church may have contributed to the problem.

I had this happen twice within the first two weeks of owning the LT. I opened a ticket and was instructed to put the Helix in an "update mode" and reload the current firmware. I haven't had this exact issue since. I have had it freeze once upon power up but no ":-28" Holding down 6 and 12 upon boot puts it into update mode. Maybe this'll help someone.

I also had this happen 3 or 4 times when I first bought the helix., same red 28 on screen and a boot up that just did not move beyond the first screen. it all happened over a period of a few days, switching it on-off then on-off again cured the problem. then after that it went back to normal, until I updated it to firmware 2, then it started crashing while I was mid way through playing, it only happened twice, I updated the firmware again and that cured the problem, that would have been really bad if it was at a gig.moving on to the present update 2.5 I have to turn it on- off and on-off again every time I use the helix now. updated firmware to 2.53 same problem still happening. I have opened up a ticket now, see where this takes me.

I suggest you try updating your firmware to v2.53.  If that doesn't fix it, open up a ticket with Line 6 Support.

Hi,

 

I have the same problem with my helix. I just bought it new about a week ago with the 2.2 firmware and it did not boot up. After turning it off and on again it worked fine. After I updated it to the 2.6 firmware but booting problem remained. I sent in a ticket so I will follow up on what happened after I got an answer.

Meetoo.

After 14 months without problems and all firmware updates made, the error slowly arrived.

When booting it was frozen, so I just restarted and no problem

but this happened more  and more even over several FW updates.

Then, one time the error -28 appeared in red letters.

After that I could boot again as before but I had to repeat the boot procedure more often to pass the boot screen.

Then, even it was passing the boot screen it was stopping after 5-10 minutes: no reaction and sometimes no sound at all.

 

Problem was evolving...so might  be a hardware problem....

 

I was sending it back to Thomann (seller from Germany), they sent it to line6 service,

Now I have to wait without a Helix :-(

Thomann said it will take 2-3 weeks ... let’s see when I get my Helix back...

Hope that they will find the error.

Sheesh.... I was getting ready to update mine, I'm a few or so updates behind. but reading this.... I don't wanna be setting up and have any issues.

 

She's pretty bullet proof right now, I read the forum for a month or so looking for these before attempting an update (got screwed before and didn't realize the faults until mid set... Never. Again.)

 

Guess I'll wait. Lol

I bought my Helix LT last july. Not a single issue with it until last saturday, when it froze in the middle of a gig. Turning off and on again didn't work, as I was getting the : -28 message in the top left corner. Have been trying to make the helix work since then. After so many ons and offs, only one time it started correctly, but froze just after seconds. I don't understand why this problem just appeared, I did not touched anything software-related in months (only little changes of volume, gains, etc.) and only tweaked the exp pedal to be a little bit softer, but i don't think that might be the problem.

It is a pity that nobody who was having this issue has come back as promised to update the thread. Did anyone get a satisfactory resolution? It is very disconcerting that this issue which was first reported in 2017 by the OP, has now been reported by a new member just 17 hours ago. 

I was hoping to buy a Helix soon. Now, maybe not.

I have had this happen on occasion.  I have found that using the official power cord (or a very high quality power cord) that came with the Helix solves the issue.  Every time it happened I somehow was powering the unit with a power cable from another manufacturer (specifically Alto).

I have just started seeing the dreaded ":-28" of death message.  I have updated to 2.71 but when I turn off and on still stuck.

 

I luckily was able to get it to boot once after playing with the LED light Fun mode and export my setlist because that would have been hours of work lost.  I must have been so lucky because the light show trick no longer works.  All other modes here work for 2/3 seconds in that I'll see a message confirming that I've booted in the different mode but then :-28 will appear top left.

 

The moment the pedal went like this I think I may have pressed a pedal to change something and then I just got this constant high pitch tone.  I couldn't even stop it with the volume nob.  I had to power it off.  Hasn't been right since.

Hello friends

I have the same problem as you with: -28,

I think that with the price and quality that supposedly this type of tool should have, it should not have this type of failures that apparently is viral

I propose a major complaint to the manufacturer, so that it deals with and takes care of its responsibility,

thanks and best regards

Hi folks, the same happened for me today. First, the HELIX froze, then I tried to start it twice and got the ":-28" two times. Now on the Helix are running at the fourth attempt. This has never happened for me before.

I would do a complete factory reset: 

 

https://helixhelp.com/manuals/helix/resetOptions.html#helix-floor-lt

 

If you are concerned about saving your IRs or presets do a backup first. Then after the reset, reimport them.

 

Hi,

 

As I understand it, the feedback from people who raised a support ticket regarding this issue, is -  you should restart your Helix LT while holding down footswitches 6 & 12. This puts the unit into “Safe Boot” or “Update” mode and from there you should be able to re-install the latest firmware.

 

The thing is, I get the distinct impression that most of the people on here are asking for a fix out of pure desperation after having tried all the usual reset routines.

 

Let us hope that anyone suffering this fault contacts Line 6 customer support and make them aware that this is an ongoing issue.

I actually recommended using footswitches 9 & 10 to reset setlists to factory, perform a global reset and clear IRs.  This is more extensive than the option you mentioned above.  Try it!

Hi,

 

Yes, I’m fully aware of what that combination of switches achieve and yes, I have tried it on many occasions, but thanks for the tip!

 

The reason I mentioned 6 & 12, was because I was re-stating something that has previously been known to work.

 

I actually refer people to the full list of reset options available quite frequently on these threads - as they do come up a lot.

 

For your entertainment here is the list of button presses and what they do - enjoy!
