Question about Gateway FPD 1750 17" Flat Panel LCD Monitor

2 Answers

I have a growing black horizontal line on my screen.

Hello, Last weekend I noticed a small glitch on my screen. It was a small black horizontal line in the lower right side of the screen. I figured it might have happened from my 18 mo old doing something to the screen. But now it is growing! Over the course of the week it has gotten 3 times as big. It is about an inch and a half in size now. What could be causing this and what can I do to fix it. My computer is out of warranty so I don't have many options there. Thanks, jamkr9

    Well, that is what I figured. Hopefully it won't grow too much bigger than it already has. I guess I will have to start looking for a new monitor. Thanks for your help and your swiftness in getting back to me.

I've encountered the same thing on my lcd. i'm of the type that can't wait untill the dealer is available to answer my questions, so i opened the machine up to get the answers by myself. It turns out to be moist, instead of a crack, which causes oxidation. This explains also the fact that it grows. It is obvious that this cant be fixed... I'm sorry to confirm that your child probably is the cause, but hey, at least it wasnt done by a cat marking its territory, like it was in my case:)

Sounds like that there was a small ding or crack in the crystal display and as all glass does when it gets cracked the crack will grow. unfortuatly theres not a thing to do untill it breaks or live with it Sorry about the bad news.

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 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: 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.

My Sharp LCD tv has lines going from the sides to the middle. They started small and continue to grow...getting longer and wider.


Hello,

All Plasma and LCD TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken Good luck in solving the problem and do take care in handling the set because it contains high voltages.

BLACK GAP ON RIGHT SIDE OF TV SCREEN


This is a sign of an aging horizontal deflection circuit. Go through your initial setup menu and see if the set gives you the option to adjust 'width.' This may have enough range to stretch the video to the edge but it will also affect the geometry of the displayed video.
As of now, the component most likely growing old is an electrolytic capacitor in the horizontal circuit that has lost value. It is usually a bipolar capacitor in the range of 4.7 - 33 uFd. It will likely continue and become more annoying and if you look closely, you can probably see that the geometry of the picture on that side is not as it should be; it will often appear 'squashed' together.
Allowing it to just grow may result in the failure of the flyback (a high voltage transformer) and/or the main power transistor that drives it.

Black horizontal lines


Sounds as if you have a bad capacitor in the horizontal deflection or video circuitry. You can spot a bad capacitor in circuit with a ESR meter.Hope this helps.

Horizontal Lines On Screen


horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,

but its a horizontal sync problem.

if no change the horizontal processing ic.

Hello, one of possible solutions is to replace capacitors (10uF/50V) on HYPER (PD0246) module. Please ask the tech to check/replace them. If you need more info please advice.
