You need to replace the vertical IC U02 ( LA7830) and C17 (100uf 50v) Link to comment Share on other sites More sharing options...

0 Virgil Tracy Posted April 23, 2008 Author Share Posted April 23, 2008 Replaced the IC and cap and still the same, any ideas? Link to comment Share on other sites More sharing options...
0 Jomac Posted April 23, 2008 Share Posted April 23, 2008 Could be an open winding in the flyback or the fusible supply resistor for the IC will be open . Link to comment Share on other sites More sharing options...
0 Heathsarcade Posted April 23, 2008 Share Posted April 23, 2008 sounds like a resistor now since you have changed ic and cap otherwise yeah flyback if your components have not burnt up it should'nt be that hard to find good luck Link to comment Share on other sites More sharing options...
