Hi, Have you got anything connected to any inputs at all? If so have you tried removing them to see if the 'noise' disappears?

Have you checked for domed or bulging capacitors as one may be faulty and introducing a 'ground' into the circuit?

Try taking some close up pictures of the pcb and posting them here. Perhaps someone can spot the problem Adding images to an existing question


Sir Jayeff thank you for your inputs, nothing connected on the i/o's and let me double check on all capacitors sir.
