CLOCK NOISE
ON SOUND
When selecting CENTRE speaker or AV4
mode, you can hear clock noise in sound when
volume level is increased
more than half. This is caused by cross-talk in
the cable. AV4 sound and centre sound are
located after audio decoder (MSP3410) which
leads audio input impedance
Screened interface cable cures this problem. It will be applied after
trail 100 Q’ty. For 100,
DMD send HEL
improved one.

RGB MODE
STREAK
NOISE
When you see streak noise on RGB input, this is
caused by clamping error accidentally.
In service mode, check SVC > OPT > RGB Comb = off

MENU
WIDEMODE
When you select MENU, picture wide mode is
changed to WIDESCREEN wherever wide mode
is.
This is because OSD is inserted BEFORE a picture is scaled
to any of wide modes. If a picture is zoomed to LETTER
BOX or T16:9L, some of the menu is hidden if wide mode
remains as it is. This system gets TV+TEXT feature possible.

PC WINDOW
LIMITATION
When selecting PC window, sub picture is
displayed. Sub picture is not possible to display
YPbPr and PC so those are prohibited to be
selected.
By AV key selection, AV4 and PC is skipped. AV/PC in
position, FRONT is displayed when selecting the position
where AV4 and PC is stored. In case of AV in position
ideally that psotion should be skipped. But it is not easy for
software to carry out so FRONT is selected as alternative to
blanking.
