Firstly I'm sorry if this is in another thread, I looked around but could not find the same topic. So if anyone knows of a previous thread just point me in the right direction, and I will say sorry to all.
As the title says I recently bought a grey DMG-001 from Super Potato in Akihabara (Japan), got home put in my LSDJ cart, turned it on and only got the jumbled Nintendo sign. I repeated this many times after blowing on the cart and the cart socket in the DMG but to no avail.
I then tried this with a Tetris cart (I bought only for testing purposes) and had the same result.
I know these carts work because I have been using them on another DMG I have for a while now.
So before I decide to go back to Akihabara and talk to the shop people, I was wondering if anyone here has any advice so I can fix it myself.
Besides it was only 3000yen so it would be easier to fix before making a claim to the shop.
P.S the only thing that the shop stated was wrong with it, is a scratch on the screen.
