MFD won't come on but did come on five minutes later. The radio goes on and off every three seconds.

2009 Prius. MFD would not come on when I started the car but it did come on about five minutes into my drive. Now it won't come on at all except for a brief Toyota logo at startup. It is getting power as you I see a slight glow on the screen at night. Also my radio goes on and off about every three seconds. I have pulled the plug out of the 12v battery to reset everything. I've also unplugged and plugged in the connections on the back of the MFD. My 12v battery is low but I put a full charge on it but to no avail Still no MFD. It only has 104k miles on it and is in like new shape. Can someone help me with this problem please? These forums are great!
I did check the fuses under the hood but is there another fuse box inside?
