Unit had defective Convergence output IC's | Muller |
Sony | KP41EXR96 AP | dead | .KP41EXR96 unit dead. Will not power up. But will turn if the convergence board is disconnected | The 15 or -15 volt supply was missing?.Diode D605 shorted. Tech should check all devices on the + and - 15 volt supply line as well as the 4 post regulators on the ""D"" board. Tech found a shorted C1742 located on the ""D"" board. It connects between the -15 and + 15 regulators IC905, IC906. "" | Muller |
