Pull plug 1516 that connects the SSM to the LSB and see if the set fires up. This plug carries the +22, -22, +35 and -35 from the LSB to the SSM. When you have shorted STK392-120's, removing this plug, unloads the shorted IC's, and the set starts. This quick test will save you from needlessly changing the convergence IC's. Remove the plug 1516 from both the LSB and SSM. It plugs in from both boards. Snip the wires to pins 10 and 11 and plug it back in. (There is enough slack to resolder them later). These pins supply the + and - to the audio IC. When you snip the wires and the set starts up, you have a bad audio IC. If it still does not fire up, you more than likely have convergence IC's bad. ------------------------- Location: Far, Far Away
