There's a picture on the screen, but it has lines all across it.Sometimes it will be clear, but most of the time it has lines. I also have directv, but they've installed a new box. Is this my television...


Hello
If the lines are there, and are across the screen at about an inch apart the whole screen from top to bottom, it is due to a slight increase in your TVs screen votage. It can be adjusted.
Open the back cover of your TV. There is an LOT [Line Output Transformer], can be seen directly soldered to the printed circuit boar of your TV. It is the largest component inside your TV, which have usually three wires emerging from it, and one thhick wire goes to the final anode of the picture tube, and will seem to be sticked to the top of the picture tube with the help of a rubber ******. Other two wires goes to the base card of the picture tube, a circuit board.
The said [LOT] has two controls integrated on it facing you as you open the TV. Among the top one is focus control, and the bottom one is screen control. Both of them are variable resistors, help to adjust focus and screen voltages respectively.
As set powered on, keeping the brightness, contrast and colour controls to its minimum, turn the screen control a little bit counterclockwise [not more, a little bit] will eleiminate the lines on your TV screen.
Take every precautions we have to, when working with an electrical equipment. Keep children away from you while you are working on it. Never allow them even to come beside you. Keep an adult beside you as a precautionary measure. Ok.
Wish you all sucess.

I have a 27 inch sansui television. It is about 5 years old and white lines have started to appear at the top of the screen. They are kind of annoying. Does anyone know what that is.


If your TV has a picture tube rather than an LCD display, you have a problem with the vertical circuit
(the circuit that "paints" the picture from top to bottom). Usually a capacitor in this circuit will open up causing this type of problem.

My sony tv falldown from the table color problem (rainbow pattern) developed but picture is ok. how to solve the problem?


It knocked the inside color wheel or tubes out of alignment. Check menus for "convergence" and try to readjust. You may need to call in a pro to fix it, but search your model number on trhe net and see if you can find the service manual.

Picture cut off Screen on Tube TV


Is the extra width problem something new or has the condition always been there? If it is something new, probably the power supply regulator has failed causing overvoltage to the tv.

AKAI CFT2726 picture sides cut off.


If it is a picture tube type TV not a plasma or lcd try degausing the picture tube. I think Radio Shack carries degausers or find the plans for one on the net.

Sony gv-27v42 27" tv picture cuts out after a few minutes


Vertical lines down the center only means that you have a loose connection on the Yoke. Re solder all the connection on the yoke and where the yoke connection meets the main board.75481bd.jpge307a54.jpg

Picture tube doesn't seem to stay in place (standard tv)


A very good chance this tv was dropped or bumped. Sounds like the internal plastic frame is broken and will not support the picture tube. Find someone with tv experience to fix this. I would suggest they use a putty found at an auto parts store. To glue the tube and the frame together. This putty is in a plastic tube. You tear off a piece and fold it several times to activate. It will surely do the job.

Picture is cut off on top and bottom


Thats is not going to fix your problem. You have a bad vertical output IC and or a bad capacitor in the vertical drive or output circuit. Good Luck

The picture is round


No my freind, im afraid that you have bad waveshaper capacitors in the vertical sweep circuit in your TV set. This is not an adjustment. you should have a pro assist you with the repair of this set as it is dangerous because of the high voltage inside these sets.
