What could cause a single dead line on the display?

Hi, my right display was out. I was able to get it working again with a hot iron. However, it still has a single pixel line that is dark, even after several tries.

Looking at this link, it seems that a line in the ribbon cable controls 8 pixels on the display. This would mean that my single bad pixel can't be caused by a ribbon cable problem:

Could it be a defect in the LED? What else might cause this?

I have a system that I got the permanent solder fix for about 4 or so years ago (by a skilled member of PVB, not some eBay hack) and it had worked fine but recently now has a single dead line in one display and I had been meaning to ask this too.

So it sounds like that LED board is shot and just needs to be replaced? (i.e. can't be repaired somehow?)

Unfortunately yes, the LEDís on the board are so tiny, replacing it without a robot isnít possible. If you want a new one, youíd have to get an additional VB unit, since you canít get the actual LED board anywhere else. (I had to get another donor VB for this reason, but itís not a bad idea for other replacement parts as well) I recommend buying a ďbrokenĒ one so you can get a cheaper donor since the displays may only need soldered to be fixed most of the time.

there are ebays hacks lol i delt with them. they just do the heat fix. that why im on ebay too to make sure its done the right way.

unfortunately there is no way to fix a bad led. there just too small.
