Gateway EV500A 15" Monitor

I got problem to adjust the Horizontal side of the screen.The horizontal screen goes beyond the edge of the CRT on the right side of the monitor so I can see whatever is display on the right side. Hope someone had come across this problem and help me out.I had seen somewhere in the internet that I need to replace a transistor but I cannot remember what was the transistor and what location on the pcb.Thanks

SOURCE: a thin horizontal line across the screen

I know I have seen thin lines in the past on older CRT monitors, these are usually wires which support the aperture grill. LCD is just a panel so this must be something different. What color is the line? It is probably an error in the scanning process.

SOURCE: Horizontal output transistor keeps failing

The horizontal output transitor is always connected to the primary winding of the flyback transformer (via collector) and also to the horizontal deflection coil via an electrolytic capacitor. The most likely suspect for damaging the transistor is the fylback transformer. In some countries there are electronic stores that test flyback transformer by winding a few turns on the ferrite core and applying a test voltage. This test will only test the secondary. The primary winding is difficult to test for turn to turn short because the resistance is quite low and you do not know the 'good' resistance.

SOURCE: horizontal lines on Screen

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

SOURCE: monitor horizontal adjust no function

It is the problem of horizantal section.Check horizantan hold transistor that is placed on hitsink of eht and two small transistors near iton pcb.and check horizantal yoke coil pins for dry soldring or low voltages.If thats are ok then change hori. &ver. deflection ic.
Hope this solution works.i am always for you

SOURCE: horizontal lines on my monitor

Lines on screens are usually caused by damage to the ribbons on the actual screen face itself (something only a few professional lcd repair shops can repair).
Sometimes caused by a bump, other times from over-wetting when cleaning, or dampness/moisture issues
The inverter-power board does Not control picture, It just controls the backlight bulbs and powering the video board.
Picture is powered from the video display board.

Explain how the monitor buttons work


Monitor Icon Description of icon function moncont.gif 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.
Corner and Trapezoid Correction - Using this button or wheel the user can either round the edges of the picture or move the picture inward like an hour glass or outwards.
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.
Power Management - Allows the user to define the power management settings through the monitor itself and not the software.
Monitor Status - Displays the current monitor settings such as refresh rate and other settings.
Language - Sets the language on the monitor.

Which service manual setting controls horizontal size?


You're discussing about the factory mode adjustments. The horizontal width adjustments will not be there. You have to adjust it by replacing certain capacitors at the horizontal output stage.

My monitor does not display full screen though all the settings are OK. This problem has just emerged recently. The vertical size is fine and the horizontal size is the affected size.REMEMBER ALL THE...


The Horizontal power supply voltage is low. This is provided as a "sawtooth" waveform via the CRT flyback transformer.

Some flybacks offer a voltage adjustment via a potentiometer ("pot") on the side of the unit. I do not have a schematic for your monitor, so I cannot tell you for certain if this is an option. This adjustment should only be made by a trained technician. If you are not familiar with high voltage electronics, DO NOT OPEN THE SET!

I recommend replacing the monitor. When they age, you can only buy some time before it goes for good, and prices are so low now that repairs are not usually cost effective.

Black at left and right of monitor


Since this is a CRT monitor, it doesn't have a native resolution like LCD monitors. You need to adjust the veritcal and horizontal sizes to fit the monitor. On the front of the monitor there are some menu buttons. You need to open the on-screen menu, then navigate to the Horizontal Size and Position menu, use the plus and minus buttons to grow and shrink the image. If it's not centered, use the Horizontal Position menu to move it around. Use this same system for the Vertical menu and you can get your image to fit your screen. By the way, you should have your operating system running with a white (or light colored screen) up when you do this so you can see all the edges of your desktop. The buttons are tricky, but they kinda make sense. Good Luck!

Horizontal/Vertical Postion of Image on LCD Monitor


the controls for focus adjustment are on the flyback transformer, (that big black thing on the left hand side (usually) of the monitor with the thick red wire that goes to the CRT.) the flyback may have 1,2,3 or even 4 knobs on it. 3 of these would be labled SCREEN (bottom knob of flyback. handles brightness)
FOCUS 1 + FOCUS 2 (focus adjustments. these are what you need to play with) and the 4th knob (some old mitsubishi workstation monitors had these) i do not know, it wasnt labled and HV adjustment was on the deflection board
