More than likely the internal fuse. Dead easy to check and change. If you take it to a repair shop you will be looking anywhere upwards of 40 quid, do it yourself for the price of a 50p fuse.

Pop your platter off and then unscrew the cover. Then get a multimeter and check all of the glass fuses that you can see.

If its none of these then i think there is one more that you cant access from the top cover, if so then put the cover back on, leave the platter off and grab a couple of decent sized books, lock your tone arm, and then very carefully place the deck upside down on the books so the tone arm is not touching the table and the deck is stable. These is quite a few screws on the ruber cover that you need too remove, and if i remember right, you will also have to remover the rubber feet. The rubber cover can be quite stuck on so give it a little bit of persuasion, and the check the fuses in there.

ps - remeber to take the fuses out before checking them as you may get a false postive if you leave them on the board.
