First off I am sorry if this has already been asked or the answer is around but I couldn't find it. So i just bought a f700bt off craigslist and hooked it all up right then it worked fine for a little bit then went to the boot up pioneer screen and it started blinking then I reset it it worked for under a minute then went it back it keeps doing it I don't know anything about this as this is my first one any help would be great thanks in advance chris
