Intermittent vertical lines

My sony monitor works fine as a monitor but has developed a failure mode as a tv with vertical lines appearing after warming up. I assume that it is a problem with my FX 5200 video card and if so what can be done to fix it? I have upgraded the driver but the problem still exists.

I have thin vertical lines


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.

Hi..pls..help..my jvc television, im watching then turn off have a power but sadly it has a line at the middle of monitor and turn off.


You have a vertical amplifier failure or dry solder on the vertical IC. When cold if the TV works for some time and then you are getting a thin white line in the middle of the screen after some time -- its a dry solder problem. The vertical IC runs very hot in the TV and develops dry solder after a few years.Will run when cold and switch off when hot.
Are you well versed with electronics to do the repair yourself ?. If so, revert back and I will guide you if you mention the TV model #.

On power up I hold the power button down, I can hear some sort of relay kick-on, sometimes a horizontal white line appears across the screen, then it kicks-off, and the red led blinks four times...


Hi,
White line across the screen indicates that tv got vertical deflection failure problem that may be due to vertical output chip failure. If that kind of problem occurred, tv select protection mode and red light starts blinking 4 times.
Please check vertical output chip in tv main board and replace it to solve tv issue. This job needs soldering work so local tv repair shop will help you.
Thanks.

No picture. Just a vertical line accross the screen.


When this kind of set comes in for this problem, it is typically caused by a leaky/intermittent diode D402, located next to the heat sink for the vertical deflection IC. I will typically also replace the vertical deflection IC at the same time, just to avoid repeat failures.

My viewsonic vx2835wm has developed vertical pixilated lines


First thing you need to do is figure out where the problem is originating from. The monitor or computer?

When the lines appear, try the following:

1. Press the [1] on the monitor to bring up the menu. Do the lines appear on top of the menu?

2. Change the input. Do the lines appear on a different input?

If you answered "yes" to any of the question above, then your unit will need to be serviced.

If you answered "no" then test the monito on a different PC and verify if the problem follows the monitor. Also, try using a different video cable to rule out a bad cable.

Do the lines only appear when you are playing a game? Does it only appear on certain games? What resolution and refresh rate do you run the monitor at?
