Black Bar on screen

If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

Can u change the screen from 16:9 ratio to 4:3 or regular if it's available in the menu? Black bar at top and bottom generally signifies widescreen...16:9
...

Press DEL on startup and select "last best known config that worked" If that doesn't work you have probably corrupted the Win registry.Will need to take back to store, beware that if its a software fault you will have to pay and may lose all your data n the HDD!!!

There is no invertor board on a plasma tv. The fault is the X address buffer board. This is located on the bottom of the screen and runs horizontally the whole width of the screen. If you remove the heatsink plate that covers the x address boards and you need to look at the screen ribbon at the same position as where the bar is (in the middle).Vary gently lift the Xbuffer ribbon lock and gently take out the ribbon.Clean the contacts very carefully with a fibre pen or an electrical cleaning fluid.Insert ribbon back and heatsink and check.Here is a picture of the board and ribbon


a 1 inch bar is associates with 1 ribbon fault. So if the bar was 3 inches in from the left of the screen, the faulty ribbon will be 3 inches in from the right working from behind the TV. If cleaning dont cure the fault, then the Buffer IC will be blown and order a new centre buffer board (you can buy off Ebay)

Sounds as if screen is going out..

hi...
It sounds like an Intergrated Circuit (IC) has fried.
Your best bet in this situation is to contact ur tv service operator and let them recommend an authorized service center in your area....

Right Click on an open spot on your desktop.

If your Operating System is Windows XP, choose Properties from the menu box that pops up when you right click.

A new window will open up. Click the Settings tab at the top right.
On this menu you should see a slider bar near the bottom left under "Screen Resolution". Left Click and hold the mouse button on the grey button and move it on the slider bar over to the right one spot. Then click the Apply button on the bottom right of the box. The screen may flicker for a second and your desktop will change size. If the screen covers the whole monitor and the black bars are gone, that may be the correct resolution. Click OK on the box that has a timer and is asking if you want to keep the screen that size. If the screen does not look correct, click No and you may need to slide the button one more spot over and try the next resolution and Apply until it looks correct.

Under the slider bar as you move it over a line at a time will be 2 numbers like this 1024 X 800, and when you move the bar over the numbers will change. I believe the optimal resolution setting numbers for the 20" monitor you have should be 1680 X 1050 for the widescreen. You may want to try that setting. If it looks too small, try sliding the bar to the left and try each resolution setting.

Here's a screetshot of what the Box with the slider bar looks like: http://technophobik.co.uk/vxp_control_panel/f007_settings.asp

If you have Windows Vista, (it is similiar to XP):

Click the Start Button and click Control Panel in the Start Menu
Click Appearance and Personalization in the new window that opens up.
Click Personalization, then click Display Settings at the bottom
A new box will pop up with the grey button on a slider bar near the bottom left under "Resolution" Slide the button to the right to the next line one spot over on the slider bar and then click the Apply button. The screen may flicker and change the size of your desktop. Click OK if the screen looks correct or click No if it doesn't look correct and try sliding the button over one more line.

There are horizontal and vertical relays in plazmas that go out over time and cause this to happen , You can get an estimate from a local tv repair service in some cases they can give it to you over the phone. Good luck.

All LCD displays have an "Auto" button press it and see if that fixs it. should be aparent what it does if it does it. but basicly it alines the picture with the screen. when you change back to user profile you may need to press it again.

Hi...there,
The problems.. your panel are damaged. Don't bother to replaced...will cost you a lots of $$$.... It's time for retired...
