(5-5) ARP RAM Check
Data write → read, and accord check
Error 11 : ARP RAM read data discord
The program code data stored in ROM are copied to all areas
of RAM (IC1003) connected to the ARP (IC1002) through
the bus, then they are read and checked if they accord. If the
detail check was selected initially, the data are written to all
areas and read, then the same test is conducted once again
with the data where all bits are inverted between 1 and 0. If
discord is detected, faulty address, written data, and read data
are displayed following the error code 11, and the test is sus-
pended.
6. AV Decoder
(6-2) 1933 RAM
Data write → read, and accord check
Error 13 : AVD RAM read data discord
The program code data stored in ROM (IC1105) are copied
to all areas of RAM (IC901, IC903) connected to the AVD
(IC902) through the bus, then they are read and checked if
they accord. Further, the same test is conducted once again
with the data where all bits are inverted between 1 and 0. If
discord is detected, faulty address, written data, and read data
are displayed following the error code 13, and the test is sus-
pended.
(6-3) 1933 SP
ROM → AVD RAM → Video OUT
Error: Not detected
The data including sub picture streams in ROM (IC1105)
are transferred to the RAM (IC901, IC903) in AVD (IC902),
and output as video signals from the AVD (IC902). They are
output from all video terminals (Composite, Y/C).
7. Video
(7-2) Color Bar
AVD color bar command write → Video OUT
Error : Not detected.
The command is transferred to the AVD, and the color bar
signals are output from the video terminals. They are output
from all video terminals (Composite, Y/C).
8. Audio
(8-2) ARP → 1933
Error 14 : ARP → 1933 video NG
15 : ARP → 1933 audio NG
(8-3) Test Tone
Pink noise is output from the AVD (IC902) to both of the
optical/co-axial digital output and the analog audio connec-
tor.
Error : Not detected.
All channels → left 2 channels → right 2 channels
