Open Question

Half of my tv screen just went black :(

The TV was working fine and all of a sudden the top half of the screen went black. There is a thin horizontal white line right in the middle and the top part is black, there is no picture, while the bottom part still works. There is sound. My TV is a Sony flat screen, 24 inch and about 4 years old. Does anyone know if there is a way to fix it?

    The exact same problem happened to me last night as Lymile. No warning. Black top half of screen. Separated by bright white line. Normal picture bottom half of screen. Sound is fine. Picture is not compressed. Heads of people on screen have been chopped off. Same picture with DVD. I get a complete picture with my "picture in picture" as long as the "PIP" is located in the bottom half of screen. My TV is 20 days short of 4 yrs. old... Tom

SOURCE: SONY KV-27FV310: UPPER HALF OF SCREEN IS BLACK

You have a vert sweep problem and unless you know how to trouble shoot this cuircit bring it to a pro. I found out mostly in these sets that the vert output IC is bad.. Also sometimes the b+ filter cap off the fly is leaky and made the IC to fail. Another thing is Im surprised to hear you got a pic with the vert failure and a bright line in the pic!! This could be a big problem when the sets fixed so dont run it too long like this. It could burn a line all the way across the screen and you will see a dark faint line in your pic because of this. BE CAREFULL!!

Why half screen is ok, other half I.e. bottom part horizontal lines are seen.

Your LCD or Control Board is damaged. You can replace the LCD or the Board or have someone do it for you.

The top half of my Sony Bravia 32" screen plays as

Hi,
I'm sorry, it sounds problem with lcd panel (screen) that is defective and causing lower half distorted image. If tv is under warranty then call number written on warranty documents for warranty cover or lcd panel (screen) replacement would cost you approx 80% of new tv price.
Hope these info will help you.
Thanks.

Black line running horizontally across TV screen

A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.

Sony TV - Loss of half the picture

sarge, it sounds like the vertical output IC went bad on you. If it was a bad connection or a bad capacitor, your picture would have been a straght line across the screen. They call the output section of the IC a push-pull type of amp, so the top half of the sweep IC went out. If you have had some soldering experience, and or experience with solid state repair, locating the bad IC and replacing it is no big deal. If you havent, stay safe and call in a pro to assist you in this repair, as there is alot of high voltage inside this puppy that is still present even if the set is unplugged. It should not cost an arm or a leg to repair this set. An honest repair on a set like this if you take it in should not exced 125 to 150 bucks. Good Luck PS Please dont forget to rate this thread.

Top half of screen black

The vertical circuit is going bad,this is the one in charge of opening the picture up and down,try taping on the side to see if the picture reacts ,if it does your set has a loose conection and the vertical IC will need to be resoldered only but if it does not react the IC will have to be replaced,if you are familiar with tv service this will give you a place to start but if you are not be safe and seek the help of a servicer,please let Us know how it goes.
