My Ledtriks panels have been in use for 5 Christmas Show seasons and I discovered one column partially lit a couple of nights ago, with one LED out. We pulled it down from its perch 15 - 18 ft above a bay window and replaced the "dead" LED, all was then fine and we re-installed it.

I see tonight that the same LED is out once more, and the same column is partially lit again. When I tested the LED that I removed a couple of days ago it appeared to be fine !

Suggestions please - is it "another" faulty LED, or do I have a faulty driver chip. For the record, not that it really matters, the "dead" LED is in column 46 and row no 4. I suspect that I have replaced that LED before as I found a mark alongside it noting it's position when I got inside the box !
