SVM is activated by default when shipped from the manufacturer. This feature distorts brightness and geometry for the sake of "improved"
contrast and sharpness. To read more about this, click here.
To combat the ill-effects of SVM, below are four possible ways to disable SVM on the
Toshiba set:
To do the SVM, now remember, this is general. The manual may help with this, and I take
-0- responsibility for your actions.
UNPLUG YOUR TV FOR A FEW HOURS.
Remove the speaker grills.
Unscrew the center front grey piece. There should be 4 screws per side. This will expose
the circuit boards attached to the lenses. You will also see a thick metal protective
piece. A ground wire goes to the bottom right screw. You will need to remove this
piece. You will then see lots of stuff you shouldnt touch!
Look at the circuit boards underneath the center lens (the Green gun)
The service manual peice is deceiving, the SVM board is neither small nor in the place
they describe in the pictures.
Look at each of three lens/tube pieces. You will see a circuit board on the bottom of
each. The center one, the Green gun, will have an extra circuit board about 1/2 to 3/4 of
the way up.
>> That is the SVM Board.
You will see 4 sets of wires going to it. One has some grey wires, for power. There are
also 3 sets of 2 wires going to each of the 3 lens/tubes. One on the left hand side for
the red, one in the front of the board, on the right hand side, for the green, and one on
the right hand side for the blue. On mine they were white, and white with a pink line.
They have small beige plastic connectors similar to a computer system fan connector but
tighter.
You need to remove those three connections from their sockets. Then secure them somehow
to something else so they don't accidentally short on something (not terribly likely
but...)
That's it! Its really simple, maybe 15 minutes of work if you go real slow. Use needle
nose pliers, especially for the center connection. Don't touch anything you don't need to!
Look for dust and make sure everything is snug and in place. All of the other
connections in the TV should be in good. This is just a "you should do it cause you
are there thing" and not necessarily part of the SVM procedure.
Put everything back together, remembering to put the bundle of cables that were held
onto the metal protector back in the cable runners, and to put the ground wire back into
place on the protector.
Go check out Clay
Cautery's site also for pictures on doing this procedure.
Some instead choose or suggest to disable this feature via the Designer Mode by setting
all SVM related features to 03 (off setting). Jeff Butsch submits that
it really should be 5 for the off setting.

Press Volume Up or Down to set the data value to "05" which is SVM off.
SVM items have 3 settings, OFF, LOW, and HIGH. It cycles through the settings >
with every three data values. For instance
02= Off
03= Low
04= High
05= Off
06= Low
07= High
08= Off
09= Low
0A= High
etc.
If you look at the factory settings, you'll see they're either 06 or 07 -- Low or
High. For Theater Mode, SVM is set to "Low", not "Off" as many
seem to think. To turn it completely off, put all the SVM settings at
"05".
