Helpful Hints Connect the Cable TV cable directly to the 751 jack on the TV. Use Auto Program as described on panel 9 to set up channels that are available in your area. Use the CH +/– buttons to scan available channels. If no Video Signal is present, the TV will display a “BLUE” screen and shut itself off in about 5 minutes. If the TV is tuned to the AV channel and there is no Video Signal present, the screen will remain black and the TV will shut itself off in about 5 minutes.

Service Modes, Error Codes, and Fault Finding 5.5 L03.2U AA 5. EN 23 Error Codes In case of non-intermittent faults, clear the error buffer before you begin the repair. These to ensure that old error codes are no longer present. If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error code and not the actual cause (e.g., a fault in the protection detection circuitry can also lead to a protection). Table 5-3 Error Code Table 5.
