4.2. Troubleshooting Please take note of the following two points with regard to troubleshooting: 1. Know-how of diagnosis upon occurrence of heavy troubles, e.g. ‘Set cannot be turned ON’, ‘Set fails to start’, ‘No display on screen’, etc. 2. Explanation of each trouble, mainly symptom of trouble in operation. ● Flow Chart START START Set cannot be supplied with current. Power lamp fails to light up. Pay attention to the following points when in pursuit of the cause of a troubleshooting. 1.
5 Power-On Self Test (Boot Check) Outline of POST The set has a boot check function called POST (Power-On Self Test) in it. The condition of the main body is diagnosed by checking beep sound or error code. z Start .............Test begins automatically when power switch is set to ON. z Normal finish .....After memory checking, a beep sound is issued once and the set is placed into automatic stop. Note: If no error occurs, nothing is displayed. (No display of OK, etc.
6 List of Error Codes The following is a list of the messages that BIOS can display. Most of them occur during POST. Some of them display information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured. Following the list are explanations of the messages and remedies for reported problems.
