The Screen turns off for a second while riding

Today, while cycling, I noticed it again: the screen went blank for a second and then came back on. Firmware version 28.20.

I have had my 1050 for a few weeks now, and have noticed the screen going blank for a couple of seconds at random times during a ride as well.  I think it has happened perhaps 4-5 times over the couple weeks.   It has been through the last couple of firmware updates without improvement (happened yesterday, I think). Current firmware is 28.20.  I spoke to Garmin support via phone and they were not really aware of the problem. 

My replacement 1050 updated to v28.20 recently. I have observed the screen problem once since then, so that's now twice since I got the new 1050 replaced under warranty. Now my original warranty is expired, so I hope this ends up a firmware problem that can be corrected.

I would hope that even if it turned out to be a hardware issue....it should still be covered under warranty, since you reported it prior to your warranty expiring.  

Based on prior experience with Garmin (have been using various Edge computers since the 800 days) I expect they would step up to the plate and do the right thing.

Same here, frimware version 28.20.  Very inconsistant, happens someting 2 or 3 times per rode, sometimes not at all.

During today's 100 km ride, I observed this phenomenon three times. And then once more when I was browsing the menu. I wonder if it's a mechanical fault or a firmware issue?

Let's hope it's firmware fixable (or at least if it is hardware, that Garmin steps up and stands behind their product allowing an upgrade/exchange.  I probably should not say anything...but I have not seen it in a couple days. 

I'm joining the group of black screens, do you know today if it can be solved by changing the terminal?

I've noticed it for the first time last week also once during a ride. 
I'm having 28.34 on my Edge 1050.
