Replacing a boiler programmer

[bblue]

Afternoon all,
A couple of questions:
1. I have a servowarm boiler, with a broken programmer. Is it simple enough for me to replace the programmer myself, or do I need to get a plumber in?
2. If it is easy to change it, can I change it from a mechanical one to a digital?

ANy help would be much appreciated!

As no one else has commented, I'll have a go.

(1) Dunno
(2) Dunno and part 2, I would think so.
