MK 195 problems

I assembled the mk 195 kit and i experience some problems…

Both of the leds are not working.
I triplechecked the + - sides, so that can not be the issue i guess.

Also, i tryed to record something, buth all i hear is a buzzing sound (nl:gezoem) , with far on the background the thing i recorded.
Now i do’nt hear anything at all.

Can you see the problem here?
(Note that i did not solded the buttens yet, as i may replace them with bigger ones, but i do not think this can be the issue now, as it makes contact?)

i would like to add fotos of front and back here buth apparently they have to be online for that?

You can find 2 pictures here, i hope someone can help me out:
