Dreamcast Console Problem

I've been having problems recently with my DC, the problem is it stopped picking up any type of game I tried to play. It would keep saying insert game disc. So I applied pressure to the lid that opens and closes ontop of the DC to see if it made any difference. When I did this the game picked right up. Now when i Play my DC i have to sit a couple of movies ontop of it for it to read the data. Is there anyway to fix this? I looked and I couldn't find any screws to tighten up the hood latch with. Also Theres a little give when the lid is closed all the way. Is this normal? its not firmly shut.
