I'm finaly stuck, at the final stage of my extensive job.. the final peice is failing.

Hear's the deal: I have converted a non smoke & sound tiger 1 to a smoke & sound one, but when I installed everything the left (lower) engine would not work properly. It did not go forward, only reverse. I thought it was some faulty connection so I resolded the engine cable and the powersuply cable (the one that goes from the battery to the main board) but no change. The only thing that happend was that now nothing works at all.. only a "clickclickclickclick" sound from the speaker when I turn the power on. If anyone could post a picture how it's suposed to look like and maybe someone knows what the heck is troubeling me? I hardly think the board is burned, it was working perfectly (except forward on left lower engine).

Please help me out, thank's (in advance)!!
