Best I can do for now

**domtorredo** · 3rd December 2013, 05:38 PM

so looking at pics can say
if original led has negative in cut corner on pcb marked with letter K and your red ones has positive at cut corner so than look at them again and you will notice that d8 led needs to be round
cant say about other one dont see them good
K letter on pcb means negative or minus
and if you will fallow traces you will find that they are nearly all conected together that means if one is incorrect than another wont light up

This pic I took yesterday before turning them around. Will try and get better pic as it Is now.

Tried reversing the smds on the other side as well and still nothing. Is it possible that some are reversed and some are not?

Really wish I never started now

. Does anyone have any others for sale?

@Pecky can you shed any light on it or by any chance you have a spare set you could put red smds in?

well as i said you have markings on pcb just look at them and check if they are like they must be
marking K is negative or minus

**paulwhite1987** · 3rd December 2013, 08:29 PM

K is negative. That's for sure. It meant I needed to line up the smd so the triangle corner was by the K. With the new ones the negative is on the other side of the smd so I have turned them all round. Needless to say I have tried them all both ways and nothing is working so it must be the board that's broke. Don't know how though. All the LEDs work fine when hooked up to the battery just not on the bord

try checking traces just look where you can hook up voltage i mean not at led
i usually check at points which are drilled true PCB so if led lights up traces are fine and soldering too if not i'm checking continuously of trace with multimeter and led itself so if led is OK and traces too than its a bad soldering

Yes I have a set of those type I could sell, but I think yours are salvageable. The LEDs are probably in series, so any one the wrong way around means all are wrong.

The factory ones do have the +ve by the K marked by red line below.
