I have a DMC 30SS. Fuse has never been changed. The vertical fuse carrier drawer, between the mains plug inlet and the on / off switch, won't prise open. It fits flush all round with a very small gap at the plug inlet side. Putting a small screwdriver into that gap won't prise open the drawer. The plastic begins to break before the drawer opens. Is there a simple way to do this ? Have I missed a secret trick ? Would heating up the assembly with a hairdryer help to release the stuck drawer ? Many thanks for help !!
