That certain led is the hardest to remove and replace because there is loads of little capacitors and stuff there! What you need to do is check you have not shorted any part of the board with solder! Also check that you have not accidently removed any bits! If still no luck, see if it'll flash!?;)

nothing is shorted and nothing has fallen off but you know when you bridge the i.c's to make the lights brighter the one on top fell off does that have anything to do with it. thanks for replying

I don't think so, I've accidently removed that one before, but I put it back on!? Make a further inspection of the board and try a re-flash!;)

yeah but it does not flash so there is no power at all and the little i.c was never put back on because it got misplaced.

Make a solder bridge over where the I.C was, ensuriong it doesn't short anywhere else on the board and try again! It has to be something simple!;)

The LED with the problem is right next to the Power Supply I.C(N100)! Big Black Square! Maybe you heated that up? My layout for 33xx isn't very clear on detail, just a map of where main componenents are!:(
