3) Data on the Decoder board (Page 3)
The data on the Decoder board are displayed. One among several subpages is for the error log for the Decoder board. You
can go forward or back one subpage using the [SIDE-A] or [SIDE-B] key. To see the error log for initialization and self-
diagnosis, after entering Page 3, press the [SIDE-A] key once. The following screen is displayed.
Note: If the Decoder board is defective, in many cases the TV output becomes unavailable. Therefore, the error records
explained below may not be confirmed.
The error records are displayed as shown below. If no error was generated in the past, "No device error" is displayed.
Device Error History
10-030305210700 40-030306093005
50-030401112233 04-030405131500
In the above example, 4 error records are recorded. The first two digits in each record stand for the error type, and the
following 12 digits express the time of occurrence:
The time of error occurrence is expressed as "YYMMDDHHMMSS." So, "030110112345" means 11 o'clock 23 min 45 sec,
January 10, 2003.
The breakdown of 2-digit error codes is as follows:
1 : Xilinx Configuration Error
Configuration of Xilinx (FPGA for PCI interface) failed.
4 : SH SDRAM Access Error
Reading from or writing in the SDRAM connected to the SH bus failed.
10 : Video Encoder Initialize Error
Communication with the Video Encoder (ADV7172) failed.
20 : AV Decoder Initialization Error
The AV Decoder (M65776AFP) failed to start up, or access to the AV Decoder failed.
40 : AV Decoder SDRAM Access Error
Reading from or writing in the SDRAM connected to the AV Decoder bus failed.
Some of the above errors may occur simultaneously. For example, "50" means the errors of error codes 10 (Video Encoder
Initialize Error) and 40 (AV Decoder SDRAM Access Error) were generated at the same time.
