Dont junk it. Even if you do decide to get rid of it, send it to me! lol... 

Anyway, It might be worth taking the back off, and the shields off. Then from that point flexing the PCB a little bit while its powered up, see if it snaps back in with a picture. sometimes the solder joints on those fail. 

there is a pincushion control board on the rear behind the flyback that has a transistor I have seen fail as well.
