Mk109 strange behaviour

Hi,
I’m a totally new beginner to solder and to electronic kits.
I need some advice please for my first attempt.
My mk109 doesn’t behave correctly (but I guess I did something wrong !).
Actually the electronic dice never shows number 5, sometimes no led are on and number 4 leds are not correctly located (LD1, 2, 6 and 7). Numbers 1, 2, 3 and 6 are fine.
Please find below links to the pictures of the board (thanks for making allowances !).
Any advice is welcome, thank you.

Hi

The components look like they are correctly positioned.
Your solder work seems OK for your first time, I’ve seen worse :slight_smile:
But it could use some little rework here and there, sometimes just heating the pad and solder again is sufficient.
Also, check if you didn’t cut the traces, check the continuity with a multimeter.
