I'm sure the problem isn't there at the arrow switch itself, but rather somewhere else where a track has been scratched, broken or bridged by something conductive or a component is faulty / incorrectly mounted.
What is all that gumph around the soldered LED contacts? Clean up the board and take another high resolution shot of the whole board and maybe we can help find the problem. Follow the traces that connect to the right arrow, B, N and / keys and see if you can spot anything odd (scratch, solder residue, etc). It could also be a faulty diode or that one of them is facing the wrong way. The black line should be on the same side as the thin line of the solder mask diagram, the unmarked side should be on the side of the base of the triangle.
Can't see the drawing under it clearly from the pictures, but is diode 53 the right way round?
thank you for your reply Oobly, D53 is facing the other way , but it is correct by the solder mask print, which on this board has the black line on the diode nearest to the thick line on the mask.
Here is two pictures as best I can get at the moment.
I can't see any damage like cut traces or bad joints, my eyes are not the best using a loupe though.
There was solder flux residue on the joints I have cleaned it off with isoprpanol alcohol , still sending "bn/" in note pad.
If I have the Leds on and press the right arrow key fast it will start to increase the brightness level of the Leds to full which is strange, makes me think the firmware maybe corupted or something like that.
We have had storms here recently, maybe it picked up an impulse or something ?
