Are you asking about the MK193 or the K8010 B/W?

3

ow :-p the k8018

i have find it but not all led are working

and all led are stand good the anode and kathode are good :-s

i ame sorry for my bad englis but i dont know ware to go whit my problem

thx

Is it a complete row or column that does not work or just random leds?
If it are random leds, then it can be a bad soldering, defective leds due to the bending of the legs or a polarity problem.

9 column dont work and ther is contakt form the ic to the column’s

the anhode and kathode ore well placed i have 0.7V over the not working leds

and over the woring led i see the voltage change form 0.7 to 1.5 that is normal i thing
measured by multi-meter

i can hardly speack english so i put it down in dutch also

ik kan moelijk engels dus zet ik het hier even in nederlands
9 rijen van boven naar onder werken totaal niet de anode en kathode zijn juist aangesloten. de spannig over de niet branden leds is 0.8 volt zonder te veranderen.
die worden pesies niet besteurd door de ic van de ic pootjes naar de leds is contakt

ik heb een standaard programa genoemen en die leds zouden ook moeten branden

I have the same problem
there are 9 colums that doesn’t work
I looked in to the schematic of the pcb and I think it will be IC3 that is broke
But I don’t know how it could happen but anyway is it possible to get a new stp16cpo5mtr ?

Carefully check all soldering points and tracks. An error is very easily made and because of the small traces and black color very difficult to see. As you reed in other topics about this kit: most of these problems are caused by bad soldering joints.

Yes I know
I had looked several times to the soldering joints with a magnifying glass with a light on the side
I also have removed the ic 3 and resoldered back on it place an there is nothing chanced.
A looked at the points of the ic and I get ground and +5v where needed on the schematic.

But mabye there was a fault by the first time I soldered the ic because it my first smd component I had soldered
