I was just about done replacing the red and green diodes on the white channel of an ebay black box and found the blue channel I wasn't working on, now no longer works.
I did scratch the board pretty good forcing one of the old diodes off, could that have severed the circuit for the blue channel? The white channel I was working on still works fine. It seems odd that the scratch would have effected only the blue channel, right?
Usually, this would be a problem caused by the diodes I am working on where I have one not connected right, but this being the channel I wasn't working on has me stumped.
I'm not super familiar with electronics, just enough to do some basic stuff like this, which I've done in the past without issue.
On this board I can't actually see the circuits on the board. If that scratch is the problem how can I reconnect the circuits? Can that white layer be removed some way to repair a severed circuit?
Thoughts, suggestions? Thx
