    Some owners have made complaints about Sony Vaio design flaws, specifically mentioning defects in the laptop's boards.Among the problems discovered after opening the laptop include burnt LCD fuses, as well as worn out circuits and internal latches. Some of these events may occur even in newly purchased units. Sony has not yet responded to various consumer complaints and has not yet issued any recalls in response to reported problems.

Check the cables. It might be overly simplistic, but if your monitor is connected via a serial cable, one of the pins might be bent or missing. This can cause slight display problems, including a vertical line. If you are using a USB, try another cable and see if the problem persists. Update your video card driver. Some discrete cards have an update feature in the properties window for the device. Right-click on your video card in the programs list, and select "Properties." The update will be a button under the "Drivers" tab if your device is so equipped. If not, visit the manufacturer's website and search for the most current driver for your model number.
Updated video drivers could solve the problem. Place a box fan directly behind your computers intake vent for extra cooling. Sometimes if there are system problems, your components can run too hot. If cooling the computer takes away the line, you know have you an overheating problem, not a monitor problem. You might try cleaning the internals with canned air. Remove the housing, and thoroughly blow any dust, hair or carpet fiber away from the fan and off the mother board. While you're there, you can check to see if there are any obvious loose connections. Connect the monitor to another computer if you have one available. This is probably the most definitive test of your monitor's health. If you have a line when the monitor is connected to a different machine, it's likely time for a new monitor. As frustrating as it sounds, taking apart one of today's monitors in an attempt to repair it is more expensive than buying a replacement. If you don't have another computer available, try shutting down the computer but leave the power on to the monitor. Using the buttons on the monitor bezel (if you have them), call up the settings. If the line appears in the menu just as it did in the video from your computer, then you definitely have a monitor problem. Replacement is probably in order

Hello yoyoxide.


from my experience can be something related with the video card. I recommend you the followig (Hardware diagnostics):

-Look for one of the discs that came with your computer, it should say (Drivers & utilities).
-Boot from the CD. If you don't know how to do it do the following:
1.Insert the Drivers&Utilities Disk.
2.Restart teh computer.
3. When you get the Dell logo, press F12
4.Select Boot from CD/CDRW-DVD (something like that).
-You will get a prompt to run the diagnosics.
-Just follow the wizard
-I recommend you to run diagnostics for everything.
-You will see if you have any problems with your hardware.

It seems that you have a pretty new laptop, so probably it's under warranty.

I am getting black spots (short black or grey lines) on clothing. The spots appear to be random. Maytag Model DE412


You left something in a pocket that melted in the heat and left those spots and lines. You will need to clean the inside of the drum thoroughly. Without knowing the source of the spot and lines, I can't tell you how to remove them without damaging the clothing.

Red Lines through picture when screen is dark, back ground has a red tint. On my 48 "Sony Rear Projection" TV


You can try adjusting the Red color output. (Very touchy adjustment)

If you take off the front cover/speaker cover, there should be a access panel. Behind that, there should be a small square black box with 6 screws on it. This is the focus block. (At least this is where most of them are located)

It sounds more like you may need less red in the mix. There is a screw for each color. R, G, and B. Do not mess with the focus screws, just the ones labeled 'SCREEN.'

Go to an unused input where the screen should be dark. Barely turn the red down in a dark room so that the red spot is at the same level as the Blue and Green.

Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it.
Very HIGH VOLTAGE. I found that out the hard way.

Do not turn any of these up too high or damage may occur and the TV may detect a short and shut off.

I have found that if the three colors are adjusted in a dark room to where the 3 color spots (R/G/B) are just barely visible on the screen at equal levels, there is a pretty good color balance.

I hope this helps! Just be careful.

The color red and especially red colored lines or a pinkish hue are indicative of an impending screen failure. The only other possibility is that the data cable on the left backside of the lcd panel may be loose at the socket or on the motherboard. 9 times out of 10 though, it is the lcd panel that it failing.

Dark Grey Vertical Bar


1. try connecting laptop to an external monitor and check if this vertical dark gray bar appears. if yes it means video is the problem. you need to boot in safe mode then uninstall the video driver. boot to notmal mode then download and install the latest video driver. if still same problem then replace video card. if video is built in with motherboard you need to replace motherboard.

2. when the vertical dark gray bar did not appear in the external monitor then it means issue is with the LCD panel. Do this turn off laptop. press and hold D key then press Power button at the same time or Press and hold on the Fn key then Power button check if the test will run. Color displays full screen when you keep pressing on N key when the colors appears check the vertical dark gray bar if still exist in the test, this means LCD panel and LCD cable needs to be replaced.
