The screen works on one side but is black on the other. separated by a series of bright color lines in the middle. All programs seem to work and computer will boot up. Bad screen or ???

Here are a few steps you can try to fix the screen color issue on your Chromebook:

1. Adjust the brightness: Click on the time in the bottom right corner of your screen, then drag the brightness slider to adjust the brightness level.
2. Check the color settings: Click on the time in the bottom right corner of your screen, then click on the gear icon to access settings. Scroll down to the Device section and click on Displays. Check the color settings and make sure they are set to default.
3. Reset the Chromebook: If the above steps do not work, try resetting your Chromebook to its default settings. Click on the time in the bottom right corner of your screen, then click on the gear icon to access settings. Scroll down to the Advanced section and click on Reset Settings. Click on the Powerwash button to reset the Chromebook.
4. Check for updates: Make sure your Chromebook is up to date with the latest software updates. Click on the time in the bottom right corner of your screen, then click on the gear icon to access settings. Scroll down to the About Chrome OS section and click on Check for Updates.

If none of these steps work, it may be a hardware issue and you should consider contacting the manufacturer or a repair technician for further assistance.

I would think that someone, somehow has hit the TV screen with something. My TV screen has a black line going across the middle horizontally and it intersects with a colored line going down the side vertically. Wher the 2 lines intersect is where it was shot with a bb.

Good day,

It seems your monitor is the problem maybe the button is stuck or something. Try bringing it to the nearest service center.

Tnx.

No,need to diagnose.It a 100% convergence problems.Convergence problems very easy diagnose.The picture look like 3D,colors lines don't lines up.Fuzzy,out of focus.Convergence controls don't work to lines up any colors cross.The tech is cheating u if he said cost $125 to diagnose.If u know how to solders u could fix this convergence problems about $100.U can buy a convergence kit at Websites Tv repair World.com,Tvrepairkits.com.The shop everythings fix parts and labors only $300.

Try balancing the tubes out, turn your color all the way down and the brightness in the middle, then find the focus block, it will be a block with 6 controls one row will say screen the other will say focus near the picture tubes, adjust the screen controls(one control for each color) until the picture has a good black and white look to it, then turn your color up and it should look fine. This is how i balance out the picture. But there is another method that allot of techs use, the other method is to adjust the brightness up until you see what is called retrace lines it is a jagged line going down the screen, once you see these lines back the adjustment down just until they disappear. Do this for all three colors. This method works but on an older set can throw the white balance off because of tube wear.

It is a bad unit. If it's new, get it replaced, there is no repair for this problem. Hope this helps.

vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

You have a failure in the vertical deflection circuit. This could be either a bad vertical chip, the power supply that runs the chip or a bad capacitor in that circuit. This is usually a repair best left to a professional. There is a small possibility that it could be bad solder connections. If genlty tapping the unit temporarily solves the issue you can try and resolder the pins on the vertical chip LA7841 is the part number. There is also a resistor 1 ohm 1 watt. If that resistor is open you can assume the IC is bad

caution whenever you see horizontal line please reduce brightness of your tv for safety of crt. your problem in vertical section only mostly due to loose contact in connector,print or loose components.

A set that has only a 1/2 inch bright line through the middle of the picture, from left to right, has a vertical output IC that is not working correctly. If the 1/2 inch line is in the middle but going up and down, then the horizontal yoke circuit has stopped working. These are problems which should be looked at by a qualified tech, but if the set was purchased 6 months ago then it should still be under the manufacturer's warranty.
