Maplin (UK) sell one that may suit you for £60 - Shop or Online.

Selectable voltage output from 12 to 24V
Any old 12V DC supply capable of delivering up to 5A will do (5A x 12V=60 Watts) i.e 60W or better.
The major issue you will have if you get a non-mikomi supply will be the style of connector to the TV set.
e-bay may be a source.
This site looks useful and possibly cheaper than Maplin

More important than the Serial Number you quote is the set's model number -
5 listed here...
