    My Problem is that I need to adjust the vertical size. I've opened the TV and found the screws to adjust contrast/brightness and sharpness, but nothing yet for the Vertical. Chasis/mainboard is CN-011. I can't find a schematic or the code to enter the service menu (which is where I fear this fix is). Any help would be appreciated

Sounds like something inside needs adjusting. There are some potmeters, usually *inside* on a TV, that can adjust where the image is located on the screen. On some computer minitors these are outside to let you adjust for different resolutions. Unfortunately, you will probably have to open the TV to adjust this, and you probably shouldn't do this yourself. Why? Because there are components inside that holds thousands of volts and thay might shock you if you touch them. *Even if the TV is disconnected from the mains!* Don't touch anything metal in there with your fingers or with a metal object! If you do open it and try, look for the small screws that can be turned. They may have a slit for a screwdriver on the end. Adjust only one at a time, and only a little until you find one that changes the property you're after (image height in your case). If the screw changes nothing, try a little more, or turn it back to where it was and try adjusting another one. A trained TV repairman should be able to fix this pretty quickly. If none of the adjusting screws helps the problem, it might be caused by a defective component, and you'll have to know quite a bit about electronics to fix it. And while you're at it; clean out any dust in there (there will probably be a lot!) to help prevent any fires later on.

Instruction manual


Hello, a manual for the Daewoo GB20H1T is available here:

http://flz.manuals.ws/cache/daewoogb20h1tcrttvinstructionbookleteng.zip

I'm not positive, but I'd imagine the GB20H1T and H1TS are compatible as far as the manual goes.

Black Vertical line appeared on my Daewoo Plasma


Bad connection somewhere along the bottom or top of the panel, there are boards most likely along the bottom of the screen that control vertical drawing, a connection that breaks as it is heated up sounds about right. check the connectors along the bottom. Be very careful because if you wreck em the screen is junk. The connector that will be at fault will be in direct line with the black bar.
