hi there,



i have problem with my naomi sanwa monitor. yesterday i connected my dreamcast with a vga box on the sanwa monitor.

everything was okay. i have played some games until the vga connector slipped out from the vga box. and thats my problem. the screen went to black with a soft "klack" and didnt came back. now i can hear the sounds from the games, but the display stays black.

has anybody an idea, whats wrong with the sanwa?



sorry for my english, schooltime is long ago : )



bye spy

the fuse is okay. i think there is a problem with the high voltage.

any ideas?

if the flyback is damaged, check horizontal deflection then change the flyback
