I have a unique problem. I hope this is the correct place to post this. If its not, I hope someone can point me to a more appropriate forum.
I have a LED curtain I purchased from China about a year ago. It has 462 LEDs in a matrix. Here is the exact model I have: http://www.youtube.com/watch?v=Yl2p9yBmWmg
My problem is that every other two strips have a problem with their color or brightness. When I had it new the color and brightness was uniform over all LEDs, but overtime this has diminished. Here are two examples of what I'm talking about:
From inspecting it I have discovered that the columns that have perfect brightness and color are directly connected to the power supply box that tells the curtain what to do, shown here:
If you cant tell from those pictures, every other two columns are connected with wires at the bottom directly, and the other two columns are not. This continues throughout the length of the curtain.
My LEDs are interesting, I can not find any similar ones online.
(shown here)
The chip on the back of the LED says "LPD6803S 1049"
More details:
The Red, Green, and Blue colors are more or less uniform, but the brightness of the two bad columns is noticeably lower than the good columns. In the other colors (purple, teal, yellow, white) the two columns show other colors, still at a lower brightness. For example, when it is supposed to be Yellow, the other two columns show Red.
Also, when I put it in solid color mode and lower the brightness overall, the colors gradually get more uniform, becoming solid at the lowest brightness.
My question is, is this a problem with the power supply, bad wiring, or some type of poor connection between the LEDs??
Has anyone had a similar problem to this, or know whats going on?
