How can i fix my sylvania SRT2232S?

One day my tv started displaying numbers and letters and you cant get it off the screen. the buttons dont work because the tv wont recieve any signal. when i hit the menu button on the tv it changes between different things. here is what it says on different screens:
1st screen- 5Z38-919 38
2nd screen- BRT 98=o(66)+u(32)
3rd screen- CNT 78=o( 0)+u(78)
4th screen- CLR 60=o( 8)+u(52)
5th screen- TNT 68=o(36)+u(32)
6th screen- V-TNT 78=o(36)+u(32)
7th screen- S-TNT 62=o(30)+u(32)
and it goes on i don't know what to do.
