Dead Roberts play 10

[technotel]

Hi
I have a dead Roberts Play 10. I found an internal wickman style fuse blown. I shorted across the fuse to see if it would work and it sprang into life. Great I thought. popped a new fuse in and its dead again. This time the fuse is fine. I get 6v out of the small pcb where the DC input and filter choke is mounted but will not switch on. I seen lots of these on eBay selling as faulty with the same problem and so it seems a fairly common issue? Can anyone help with this or know where I can source a schematic? These modern radios are like computers and cant help thinking its locked out and maybe a button pressing procedure to bring it back to life?
Thanks all and thanks for letting me join

Many thanks Edd but I have this and its not much use. I have found another faulty set and so hope to get one going out of the two and/or use the one with only FM working, as a test bed for comparing voltages on dead set.
