Can't adjust out blue picture
This TV has no guns. It has a lamp and a color wheel.
Owner reported model number as: lg ru-44sz61d dlp. Pay particular attention to the "dlp" part.
I do not know what is causing the issue unfortunately.
There are a few malfunctions that can cause such.
ONE: Mirrors out of location. But it usually throws the picture off
center, also. This can be caused if the set is dropped or kicked badly.
TWO: Out of focus. Can be caused by drift of the circuits or from a
malfunction of the video drivers. You can check this by going to the
crosshairs and see if the lines are sharp and narrow. If not, then the
focus is off badly - most likely the blue gun. You may be able to set
the focus and other levels for brightness and contrast and color to
optimize this weakness as these are all somewhat interrelated,
especially in the extreme settings. You can make adjustments for these
above what is available from the OSD by getting into the service mode.
See this web site for instructions on how to enter it. http://www.fixyourowntv.com/servicemenu.php
THREE: Worst case is the blue gun or projection tube is failing and
needs replaced - which I don't recommend due to the very high cost of
doing so.
FOUR: And it is possible the blue gun/tube has been knocked out of alignment by dropping or moving the set.
I favor the focus adjustment as the first remedy to try. You can do
that yourself. But if it turns out the mirror is out of location or
the blue gun is defective you will need a technician for help on those
items.
