Samsung CRT monitor Horizontal width control

Monitor Icon Description of icon function Power - Turns the monitor on or off.
Brightness - Using this button or wheel the user can increase and decrease the brightness on the screen.
Contrast - Using this button or wheel can increase and decrease the amount of contrast on the screen.
Horizontal Size - Allows for the picture on the screen to be stretched to the horizontal edge of the monitor.
Vertical Size - Allows the picture on the screen to be stretched to the vertical edges of the monitor.
Horizontal Position - Allows the picture to move moved horizontally, once in the center the user can then use the Horizontal size to stretch it to have an equal amount of black border on each side.
Vertical Position - Like the Horizontal Position, using this button or wheel the user can move the picture up or down to center the picture more appropriately.
Full Screen - Sets monitor to full screen.
Degauss - This button will degauss the CRT, restoring possible color impurities. After this button has been pressed the degaussing circuit will be activated and then deactivated after a few seconds. Pressing and holding this button for a few seconds may cause your computer monitor to reset all data.

Vertical Linearity - Sets the width of the vertical lines.
Moire - Removes or reduces the Moire effect, if any.
OSD Controls - If the monitor contains OSD controls, allows for the OSD menus to be adjusted.

Language - Sets the language on the monitor.

Use your brain

first of all check weather the width is getting varied from the front panel menu. if there is a vary in width but not full, then need to vary in factory level settings with the help of JIG software provided by Sansung with KIT. The KIT is connected between the CPU and the Monitor.

IF there is no change in width with the front menu, then chage the high voltage PF capacitors at Width section and EHT section(near output transistor (near LOT)).

picture tube needs to be replaced

try a good slap most times it works

u may have to try looking at options to change the monitor soon too, its a sign to say the monitors's getting old

hope this helped
pls rate

please check the width section transistor and while it is good condition please check the power diode in width section near to lot and replace the fly back capacitor that range is high volt its situated near to lot.

1. change the flyback 1600v working voltage pf.(near to Horizontel transistor.)

hi there, width means at the horizontal section problem, you have a defective parts at that section, it maybe a electrolytic or mylar capacitor, it is usully replace the parts automatically. ty

you know,in the main board of a monitor you can find a trimmer resistor in horizontal section try to rotate it while the power is on so that you cn see the effect/

To have unlock your control (auto-adjust ...) you have to hold down the "menu Key" for about an 10 seconds. This will unlock your monitor! [email protected]
