Electrically, white LEDs are usually blue LEDs in fact, with the blue light being converted to white by a phosphor layer on top. They do tend to have a higher forward voltage than LEDs in the green to red range.
Since the original LEDs burned out rather quickly, it might be a good idea to simply double the value of the existing limit resistors. You won't notice the change in brightness, and the LEDs will last much longer. And if there *aren't* any limit resistors - well, there's yer problem.
