Did you actually check element first to make sure it had failed or did you just go buy a new one & fit it just on the random chance that it may fix the problem? If no lights problem started after fitting the element then it must of been caused by something you did. Plug something else in to the power socket to make sure it is working. If not then go check the fuse. If socket works ok then either you have left a wire off or dislodged a wire somewhere or have damaged the circuit board by shorting something out.
