Helix LT -Intermittent Output Issue

[pfocas]

I had an outdoor gig with my Helix LT last week, firmware 2.51. It was sunny, but we were under a shade cloth, sun peeking through. I couldn't see the LCD screen well at all, a brightness control would be good (a feature I see has been requested). Anyway - before we even started, the unit had been outside for maybe 2 hours, was not hot to the touch, but my output going to a mixer was intermittently failing. I tried 3 different guitar cables, tried re-assigning input to the "Return 1" jack and still failed, so not cable or input jack.... Tried adding an additional output (quarter inch) to another mixer channel and both the XLR and 1/4 inch channels on the mixer failed, so I'm left with the impression that there is an electrical/electronic fault. This has never happened to me before and I practice all the time attached via XLR to a PA speaker and at home use a FRFR connected via 1/4 inch or headphones. The tuner still worked. Has this happened to anyone else? As I said, the sound was intermittent so it just cut in, then cut out again a few seconds later. I eventually re-started the unit and about the 4th time, it worked OK, now I am very nervous about using it at a gig. I can't recreate this in the last few days, but will keep testing

I noticed a similar thing when I was scrolling through some of the factory presets. A few of them don't work for me at all, they play like the cable is bad constantly cutting in and out with the signal. But it only happens on those few. I can't recall which ones they were now. The djenitrified one I think was one of them. I don't really go for that sort of sound I just thought it was interesting and a strange issue to have. I played around and replaced all of the cables I had going just to be sure it wasn't me but I kind of knew better before hand when all of the other patches seem to be just fine.

I have just bought the Helix LT and have only played with it at home to setup various patches and test a few different ways of using it. I noticed this evening when I was playing that my output level would drop away to half and then would go back to where it was. My unit did this 5 or 6 times in the space of half an hour. Checked leads and guitar etc. and no issue there. Running into some Yamaha HS5 studio monitors direct from the XLR outputs on the Helix LT.

I have just re-updated the firmware to 2.53 (which I was on before) and will try again tomorrow.

I am interested to see if this is an issue or just a little glitch fixed by updating.

any answer on cause of problem in OP?

I had a similar issue yesterday but I seemed to be able to control the loss of sound by standing in a certain place one the stage
