Mend Magnavox MRD120 New One Blows

My dvd player/receiver blew a fuse and when I put a new one it it blows???

I have a Magnavox MRD120 which needs a new fuse but when I put more in they blow once I push any buttons or turn it on. I think the problem is with the difference between AH and A that I don't understand. The player says it needs 3.15AH and 250 V but the fuse I took out said 3.15A 250V. The ones I bought say 3.15AL250V but the box says 3.15A 250 V. I just don't know the difference or what to do. I can't find 3.15AH anywhere on the internet.

Hi.
The fuses you are fitting are ok.
If they blow as soon as you plug in & switch on then there is a dead short in the primary psu.
Try checking the bridge rectifier diodes for s/c, switch mode transistor s/c, mains resevoir cap s/c & resistors.
