Hi
The most common cause of colour instability is the decoder board (top left as you look at the back of the set. It probably has a single IC on it which will be in a socket. Remove the board carefully (two clips to ease back), then remove the IC, gently polish the pins with a fibre brush or VERY fine (1200) wet and dry paper and re-insert. Treat the edge connector on the board to the same treatment and put the board back. That cures most intermittent colour and flashing faults.
The buzzing will be a choke rattiling and is annoying but not likely to cause any additional problems.
