DIAGNOSIS PROCEDURE
Flowchart
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 à 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 into automatic stop.
Error Diagnosis by Checking Beep Signal Sound The beep sound is as follows:

ERROR CODE LIST
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. 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 system
fails after you make changes in the Set-up menus, reset the computer, enter
Set-up and install Set-up defaults or correct the error.
0200 Failure Fixed Disk.
Fixed 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
controller.
0213 Keyboard locked - Unlock key switch. Unlock the system to proceed.
0230 System RAM Failed at offset : nnnn
System RAM failed at offset nnnnof in the 64k block at which
the error was detected.
0231 Shadow RAM Failed at offset : nnnn
Shadow RAM failed at offset nnnnof 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.
A POST load default values and offers to run Setup. If the failure was caused
by incorrect values and they are not corrected, the next boot will likely fail.
On systems with control of wait states, improper Setup settings can also
terminate POST and cause this error on the next boot. Run Setup and verify that
the wait-state. Configuration is correct. This error is cleared the next
time the system is booted.
0281 Memory Size found
by POST differed from EISA CMOS. Memory
size found by POST differed from EISA CMOS.
02D0 System cache error - Cache disabled. Contact Panasonic Technical Support.
02F0: CPU ID: CPU socket number for Multi-Processor error.
02F4: EISA CMOS not writable. ServerBIOS2 test error: Cannot write to EISA CMOS.
02F5: DMA Test Failed.
ServerBIOS2 test error: Cannot write to extended DMA (Direct Memory
Access) registers.
02F6: Software NMI Failed.
ServerBIOS2 test error: Cannot generate software NMI (Non-Maskable
Interrupt).
02F7: Fail - Safe Timer NMI Failed. ServerBIOS2 test error: Fail-Safe Timer
takes too long.
deviceaddress Conflict.
Address conflict for specified device.
Allocation Error for: device. Run ISA or EISA Configuration Utility to resolve resource
conflict for the specified device.
Failing Bits : nnnn.
The hex number nnnn is a map of the bits at the RAM address which failed
the memory test. Each 1 (one) in the
map indicates a failed bit. See error 230,231 or 232 for offset address of the failure
in System, Extended or Shadow memory. Invalid
System Configuration Data.
- Problem with NVRAM (CMOS) data.
- I/O device IRQ conflict
- I/O device IRQ conflict error.
- Operating System not found
- Operating system cannot be located on either drive A: or drive C:. Enter Setup and see if fixed disk and drive A: are properly identified.
Parity Check 2 nnnn. Parity error found in the I/O bus. BIOS attempts to locate
the address and display it on the screen. If it cannot locate the address, it
displays ????.
Press <F1> to resume, <F2> to Setup. Displayed after any recoverable error
message. Press <F1> to start the boot process or <F2> to enter a Setup and
change the settings. Write down and follow the information shown on the screen.
