The main power lead to my TV has been damaged (in several places, by pet rats chewing on it!) Is there an easy way of replacing the lead myself or does it need to be done by a professional? I don't know if it involves removing the back of the TV or not.

Okay, foolin around inside a TV can be LETHAL! There are EXTREMELY high voltages in there. If you open it up, oh, nevermind, you don't want to go there! :|
Plan B: The easy way out.
1. Go to Radio Shack and buy a replacement cord - it's a cord with a plug, and ends in just two bare wires.
2. Unplug the current cord.
3. CUT the cord with wire cutters close to the TV, AFTER the places where the rats have been nibblin. (If you don't have wire cutters, anything will do.)
4. Strip the wires from the TV so you have two ends about an inch long. Simply wrap the bare wires together - the + wire to the plus side, the - wire to the - side. Tape them up (cover them good) with electrical tape. Be sure to preserve polarity (+ to +, - to -).
5.Do not make a mistake.
6. Plug in. If it does not explode, you did it right! :D Enjoy your TV again.
It really IS very simple, and I wish I could just do it for ya, but I can't reach it from here! :D
All you're doin is replacin a worn cord. It is NOT hard! :)
Of course, I meant wrap the + wires and the - wires separately -- they MUSTN'T TOUCH! Am I making any sense to you? I accept E-Mail if you need more info... :D It is a very simple task. It is not hard at all. :)

Replacing the mains cable is in most cases a simple thing to do.
It will however require the removal of the back of the TV to be done properly and make a safe repair.
This is where it can get potentially dangerous if you are not suitabley skilled. A typical CRT television will have voltages in the region 25,000 volts upwards on the tube anode and a few thousand on the tube base and line output stages. It will maintain these voltages charged up inside long after it has been switched off. You can get hurt!
It will not be an expensive job but I'd leave it to a professional or someone who knows their way around electronic equipment

If the cable has a plug on both ends and one end plugs into the back of the set you can unplug it and buy a new cable-and I would recommend doing so as soon as possible.
If, on the other hand, the mains plug is connected to a cable which disappears inside the set, get a professional to do it.
I would suggest trying to get a bit of armoured cable or at least a bit of flexible metal sheathing to cover it with, the cable will be less flexible but it will be much more difficult for your hungry rats to gnaw through it.
Armoured cable is used a lot in industry but I'm not sure how easy it will be to get hold of some for domestic use-or how expensive it is.

it requires removing the back of the telly to do it correctly.
best leave it to a professional electrican or tv repairman.
If you are quite competent then remove the telly back, MAKE SURE YOU UNPLUG IT FIRST! then follow the cable to where it attaches to the power supply unit. If your lucky it will go into a connector block which you can replace the flex into it.
If your unlucky it may connect directly to a printed circuit board (PCB) then get it fixed by a professional.

If you have to ask this question, I would employ a professional. There are very great dangers inside a TV set with capacitors holding charge and likely to kill an unsuspecting and non-qualified person. BEWARE!

If it just unplugs from the back, like some do, then pull it out & get one just like it at the dealer. If it goes on inside the TV, get someone who does that sort of work to do it. It can be done though.

I've replaced one before, the back needs to be taken off, but don't try it unless you are competent

you would have to remove the back of the TV.and the TV will still have electricity in it by capacitor's.
