Darien Posted March 15, 2016 Posted March 15, 2016 Not sure If I've seen anyone else do this but I ordered some 1/16 scan 5mm LEDs instead of 2.5mm. like the "Giant Dots" displays that are available.As you can see there's some problems with the panels and I was going to refrain from sharing until I got new panels and a new speaker panel done but since I'm having replacement problems I figured I'd share. Coke can for scale They're HUGE As you can see I have a dead pixel, a constantly on red column, and two lines that are being duplicated from elsewhere I'm trying to get them exchanged so I'm not stuck like this but I don't think the seller understands I don't want to pay twice as much return shipping as I paid for the panels.

Content Provider lucky1 Posted March 16, 2016 Content Provider Posted March 16, 2016 May be the cablelength. Try to make the cable to the display as short as possible.
Darien Posted March 16, 2016 Author Posted March 16, 2016 I will say one thing for having them that large. I finally like "Video Mode" in games... I always thought it was kind of dumb, distracting, and dull. I set off video mode on IJ earlier and actually felt like I was playing something cool. Those are ginormous, they'd be great as a topper! That was my original idea. The board I got from Sacha has two hub75s. I was going with Standard 2.5mm where they belong and 5mm on top but that's where my flasher bar currently is. So I thought i'd see how blinding it was as a regular DMD. May be the cablelength.Try to make the cable to the display as short as possible. I think the panel is just busted. As soon as I apply any power to it that redline comes on. I tried pretty much anything I could think of bigger power supply, Multiple cables... Swapping the panel order. That's on a long cable but I tried a short one (like the panel to panel kind) and I had the same result. I'm not really a solder-level tech but it seems to me like some kind of logic fault is happening "after" that line.this is blank.ppm: This was the result when I swapped them If anyone has any ideas I'd be dying to try because I'm having a hell of a time getting a replacement/refund on them.

There is a short somewhere on the RED drive in that column. The very bright LED in that lit colomn either has a short turning the red on hard or there is a drive short in the feed circuit for red.. Either way there is a short on the board.. Id say that this would be causing the lit extra lines also..
