Just dug out my old Dragon 32 (actually have 2)

Plugged it in and the screen is displaying mostly @@@@@@@@&&&&&&& things like that
I was wondering if anyone knew of any possible fixes or can point me in the right direction for a guide to repair (not much on the net)

May be a problem with the video memory??

Any help??

Cheers
Keith

Might be worth opening the machine up and pressing down on any socketed chips to make sure that they are firmly seated in their sockets.
Obviously you need to do this with the machine switched off.

Phill.

Ill try that later, cheers
Hopefully its something as easy at that!!!!
cant believe its still powering up after being in the loft for 10+ years

From the service documents (hosted on this site):

D. Garbage on Screen

1. If RESET switch cures fault, then change IC17.

2. Change IC15.

3. Change IC17.

4. Change IC18.

I managed to fix it thanks, I ended up taking a circuit board from a spare dragon and swapping it with the dud one

One fixed dragon!!

unfortunately the cassette play does not work so cant play any games

Do you mean that your cassette player does not work, or that your fixed Dragon will not accept cassette input?
