6-2 Troubleshooting Procedures by Error Modes
6-2-1 Basic Troubleshooting: Diagnosis of LED on the Front Panel
6-2-2 Troubleshooting by the Checksum
■Diagnosis of trouble by the checksum is neither reliable nor convenient.
You can only use the checksume of the current direct-view TV to determine whether the software is corrupted or not.
The Checksum value is determined according to the version of the software loaded on the set.
Therefore, you can determine whether the software has been properly downloaded, if you know the correct checksum for that
version of the software.
You can check the checksum according in the following order.
Factory Mode →Checksum →Right Button →Calculate Checksum →Output Checksum (e.g. 3036)
■Checksum Examples
T-TR2PEU-1000 : checksum = 8036
T-TR2PEU-1010 : checksum = B612
Power Description
○This happens when the Master Switch is not pressed or the power cord is disconnected.
●This happens when the power cord is connected and the power switch is pressed.
