3.2 MONO PCB DIGITAL PART
PICTURE TEST
This test is performed by sending a predefined picture
(colour bar) to the TV screen (nucleus VideoColDencOn)
and asking the user for confirmation. The display will show
the following message:
By pressing PLAY the user confirms the test, pressing PREV
will indicate the picture was invisible or incorrect. Pressing
NEXT will proceed to the next test
SOUND 1 & SCART DVD TEST

9-4
PCS 103 848
sound that needs confirmation from the user (nucleus
AudioPinkNoiseOn); the display will show the following
message very shortly:
This sound will only be audible from version cut3.1 of Sti5505
(item7503 on mono board) onwards. After starting up sound
1, SCART loop-trough will be simultaneously active during
this test. SCART loop-trough will be measured with the aid
of an external video source.
When entering the SCART loop-trough, the local display
indicates:
On the TV screen a colour bar (generated by nucleus
VideoColDencOn) is visual and the internally generated
pinknoise is audible. By pressing PLAY the user confirms
the test, pressing PREV will indicate the sound was inaudi-
ble or incorrect. Pressing NEXT will proceed to the next test;
if the user presses NEXT without pressing PLAY or PREV
first, the result of this test will be TRUE (sound ok).
By pressing the NEXT button there will be switched over to
the external source, this must become now visible on the TV
screen (using the SCART). The local display indicates:
The internally generated colour bar is still available on the
CVBS and Y/C outputs. And the pinknoise-signal is still
available on the cinch audio outputs. By pressing the PREV
button, the internal generated colour bar becomes visual
again. The test can be left by pressing the NEXT key for
more than one second.
SOUND 2 TEST
The second soundtest is performed by producing a sine
sound (nucleus AudioSineOn). The signal can be stopped by
pressing the STOP-key. The display will show the following
message:
By pressing PLAY the user confirms the test, pressing PREV
will indicate that something went wrong. Pressing NEXT will
proceed to the next; if the user presses NEXT without
pressing PLAY or PREV first, the result of this test will be
TRUE (sound ok).
