[elektro] dinamikus fókusz áramkör hogy nézhet ki??

[Viktor Fuzesi]

Sziasztok,

Meséltem régebben erről a 22"os Packard Bell monitorról..

Rossz a dinamikus fókusza, ez már biztos..
A főpanelen kicseréltem a kondikat..semmi változás.
A cső végén lévő segédpanelen ugy gondoltam nem sok értelme lenne,
valszeg nem ott van ez a dinamikus fokusz aramkör csoda,nameg
rávan forrsztva 100helyen az árnyákolódobozka.

Nos, valki tudna segíteni hogy merre induljak el? hogy nézhet ki amit
keresnem kell?
esetleg A927 kapcsirajz, azon fellehet tüntetve.

koszi elore is,
Viktor

The adjustment on the flyback sets the "static" focus voltage, which is
a DC voltage applied to the focus electrode in the CRT.  However, a single
fixed focus voltage will not give you the best focus across the whole CRT
screen, for the simple reason that the distance from the gun to the screen
is different at the screen center than it is in the corners.  (The beam
SHAPE is basically different in the corners, too, since the beam strikes
the screen at an angle there, but that's another story.)  To compensate
for this, most monitors include at least some form of "dynamic" focus, which
varies the focus voltage as the image is scanned.  The controls for the
dynamic focus adjustment will be located elsewhere in the monitor, and
will probably have at LEAST three adjustments which may to some degree
interact with one another.
