Horizontal

Before you begin, perform geometry setup steps. Note Perform the horizontal adjustment steps in the order presented. Perform the step only if you must to attain the correct alignment. Important Take screen measurements with one eye, and keep that eye perpendicular to the line being measured. Using an insulated screwdriver and flexible ruler, adjust the H.SIZE control until the width of the raster is 300 mm ( 3 mm) or 11 7 8 in. ( 1 8 in.). Important Straight lines may appear bent if viewed from...

Monitor Stand

No preliminary steps are required before you begin this procedure. 1 With the monitor facedown on a protective pad, swivel the base to access the monitor stand mounting screw. Remove the mounting screw. 2 Lift the monitor stand out of the bezel. 3 If you do not plan to work on the monitor, return the monitor to an upright position on the protective pad.

Geometry Setup

Place monitor on level surface Let monitor warm up 15 minutes Warning This product contains very high voltages. When performing live adjustments, be careful not to touch the high-voltage components shown at left. Important You must perform the geometry setup procedure before performing any other geometry adjustments. (Geometry adjustments are usually necessary whenever you replace the CRT or the main board.) After completing the geometry setup, go directly to the geometry adjustments...

Convergence

Toyota T100 Horn Wiring

Before you begin, perform geometry setup steps. control on the focus control board to make all convergence adjustments. Do not touch the yoke controls. With large-screen monitors it is not always possible to precisely align convergence at every point on the screen. Rather, try for the best overall alignment with the H.STAT control. Use Display Service Utility to display the Crosshatch test pattern. Using an insulated screwdriver, adjust the H.STAT control on the focus control board until the...

Monitor Distortion

All large-screen monitors are susceptible to distortions caused by environmental conditions. These distortions are usually not visible on monitors with smaller screens. Important Even monitors set to factory specifications may appear distorted when set up in a new environment. Common environmentally-caused distortions are shown on this and the following pages. Always check first for environmental causes before attempting to repair or adjust a monitor with a distorted raster.

Warning This product contains high voltage and a high-vacuum picture tube. To prevent serious injury, review CRT safety in Bulletins Safety. Warning Never use a grounding wriststrap until after discharging the CRT. Caution When removing the focus control from the CRT video board, be careful not to apply excessive pressure to the neck of the CRT. 1 Brace the CRT video board with one hand and remove the screw that secures the focus control to the CRT video board. Caution Reversing the black...
