I have a non-lighting Cobra 29 NW face plate, or EL Driver problem . EL Driver is the small metal box mounted inside, to the side, of the the Cobra 29 near the channel selector control . Can anyone tell me where I might obtain a Schematic for the EL Driver . The scielded lead that supplies the ribbon for the face plate seems to have odd voltage, 50v, and some AC, too . I tracked it back to a diode feeding the small IC on the back of the EL Driver . The power feeding the EL Driver, from side mounted transistor, seems okay, 4v-5v . All other leds are acting normally, and controled by the dimmer pot . Besides the schematic, I may need know where to buy a driver, or parts . Is there a test for the face plate ? What voltage is normal for the face plate . Any idea what the parts cost ? Any help will be appreciated on this challenge, Thanks, J
