							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 o n 
screen’, etc. 
2. Explanation of each trouble, mainly symptom of trouble in operation.

							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.

 Start .............Test begins automatically when power switch is set to ON.

 Normal finish .....After memory checking, a beep sound is issued once and the set is placed i\
nto automatic stop.
Note: If no error occurs, nothing is displayed.  (No display of OK, etc\
.)
Error Diagnosis by Checking Beep Signal Sound
The beep sound is as follows:
  = long sound (about 0.4 sec.),        
= short sound (about 0.2 sec.), Length between sounds is about 0.1 sec\
.

							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., t\
he 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 rep\
orted problems.
If your system displays one of except the messages marked below with an \
asterisk (*), write
down the message and contact Panasonic Technical Support.  If your syste\
m fails after you
make changes in the Setup menus, reset the computer, enter Setup and ins\
tall Setup defaults
or correct the error.
0200  Failure Fixed DiskFixed disk in not working or not configured properly.  Check to see if fixed disk is attached
properly.  Run Setup.  Find out if the fixed-disk type is correctly identified.
0210  Stuck key Stuck key on keyboard.
0211  Keyboard error Keyboard not working.
0212  Keyboard Controller Failed Keyboard controller failed test.  May require replacing keyboard control\
ler.
0213  Keyboard locked - Unlock key switch Unlock the system to proceed.
0230  System RAM Failed at offset :  nnnn
System RAM failed at offset  nnnn of in the 64k block at which the error was detected.
0231  Shadow RAM Failed at offset :  nnnn
Shadow RAM failed at offset  nnnn of the 64k block at which the error was detected.
0232  Extended RAM Failed at offset :  nnnn
Extended memory not working or not configured properly at offset  nnnn.
0250  System battery is dead - Replace and run SETUP The CMOS clock battery indicator shows the battery is dead.  Replace the\
 battery and run Setup
to reconfigure the system.
*0251  System CMOS checksum bad - Default configuration used System CMOS has been corrupted or modified incorrectly, perhaps by an application program
that changes data stored in CMOS.  The BIOS installed Default SETUP Values. If you do not
want these values, enter Setup and enter your own values.  If the error \
persists, check the system
battery or contact Panasonic Technical Support.
0260  System timer error The timer test failed.  Requires repair of system board.
0270  Real time clock error Real-time clock fails BIOS test.  May require board repair.
*0280  Previous boot incomplete - Default configuration used Previous POST did not complete successfully.  POST loads default values and offers to run
Setup.  If the failure was caused by incorrect values and they are not c\
orrected, the next boot
will likely fail.  On systems with control of  wait states, improper Setup settings can also termi-
nate POST and cause this error on the next boot.  Run Setup and verify t\
hat the wait-state
configuration is correct.  This error is cleared the next time the syste\
m is booted.
0281  Memory Size found by POST differed from EISA CMOS Memory size found by POST differed from EISA CMOS.

 method for checking errors
in binary data.  A parity error indicates that some data has been corrup\
ted.
