Any way to fix this ?
I've never had any such issues, but here's a couple of suggestions:
Did you try to recharge the battery (or a different battery, if you have one)?
Try with a different memory card.
I doubt you'll be able to fix this old thing. Most Nikon service centers have probably never seen one, and I'm sure it's very difficult - or even impossible - to get any spare parts. Finally, a repair is likely to cost more than a "new" camera. Too bad, but I guess it's part of the game. Still, good luck. Let us know if you're able to make it work properly.
