Information
Changes in Course of Production Änderungen bei der Produktion
INTRODUCTION ANTI-MOIRÉ PANEL
From production start onwards, an anti-moiré panel was
introduced in
the 29" 4:3 Real Flat sets with Philips CRT. This anti-moiré
circuitry is
combined with the DC-shift panel (assy 12nc is 3104 328 16661).
Involved sets:
• 29PT9007.
• 29PT9047.
Circuit diagram (G), layouts and partslist are published.
INTRODUCTION OF NEW SSB PANEL
During production, a new SSB panel is introduced. The layout
of the
copper pattern has been changed to version 8. Below, you
will find the
most important changes.
Diagram B4 (HOP):
• A new dimensioning of the HOP slow-start circuit (items
3335, 3338
and 2335).
• A new flash circuit (items 6313 and 6314 are added) around the
HOP (diagram B4).
Diagram B5 (OTC):
• A new flash reset circuitry is added, to prevent NVM
overwriting.
• To solve TXT-jitter, two transistors (7012 and 7013) were
added,
to improve the steepness of the H SYNC and V SYNC pulses. This
change is implemented together with new software.
Circuit diagrams (B4 and B5), layouts and partslist are
published.
