try finding the service manual of the TV in the Boat Anchor Manual Archive **broken link removed**

the service manual might have diagrams explaining you how to troubleshoot your TV
 
Again, I'm not familiar with Nordmende sets (but possibly it's a Thomson?), but assuming it's not 'blown up' a common cause of switch-mode PSU's not starting is open circuit start-up resistors.
