Since your LCD is flashing and doesn't show anything than most likely the board is not working properly. In that case there is no way you can get any sane MIDI signal from it. You need to find a problem in the board.

when tested before inserting jacks (not the cable) in the case, lcd screen worked.

Wat about your led.

Well first check shorts, bad/wrong wiring, bad soldering, wrong component and etc. 99% time this is only problem. I can guarantee. For me it is always turned out to one those.

Can your windows detect megadrum as usb audio device?

If you cannot see LCD then how did you programmed Atmega32.

I think your problem could be reverse polarity. It could be possible. You could have connected your usb wrongly. Like you could swapped pins of your usb.

If it not one of then Dmitri can help. I am not expert electronic expert. Again 99% sure solution to your problem can be shorts, bad/wrong wiring, bad soldering, wrong components and etc. This turn mostly for me and my observation on forums.
Still I have bothered Dmitri But i dont know why?

What jacks are you inserting which makes the LCD go bad?

I'm confused. You should solder these jacks, not insert them anywhere. Anyway, return to a state without these jacks. Does the problem go away as it was before 'inserting jacks'?

[lidel]

they all have been soldered (sorry for my english) and checked with a tester
