Vertical sweep failure.
It will be an I.C. with a part number that probably starts with an LA_ _ _ _ and be on a heat sink in the vicinity of the connector going up to the yoke. Try replacing that. But first, check all the electrolytic caps around it for testing dry (sorry - takes a special meter to do it in circuit) or just replace them. May have lost power to the I.C. as well. Look the I.C. up in the free NTE crossreference at nteinc.com get a diagram of its pinout to find what pins the power and outputs are on.
Hope ya fix it!

Blank screen except for a single horizontal line through the middle of the screen.


Hello

Your TVs vertical swee sction has failed. All CRT based TVs have both vertical and horizontal sweep sections to sweep the picture both in vertical and horizontal direction to display it on the picture tube screen. This process is otherwise called as scanning. If vertical scan section fails, you will see a horizontal line at the middle of the screen and if horizontal scan fails, you will see a vertical line on the middle of the screen.
You have to open your TV to retify this fault, as the fault lies in the internal circuit board. Open it after disconnecting it from the mains wall socket, and locate the vertical output section inside. It is very easy to locate. On opening you can see a coil fitted on the neck of the picture tube, called deflection yoke, and there will be four wires from it goes to the main board. Out of which two of them will be thick, and the other twos will be thin. The thick wires are usually colour coded as red and blue. Just follow the two thin wires. You will reach to a plung in socket to which these four wires together connected. Turn upside down the circuit board, and follow the print track through the print side of the above said two thin wires connection goes. it will go to the vertical output section.
Before doing any thing, first look into the circut board for any loose or bad solderings are there. It is a common fault that this section have loose solderings on it, because most of the components will heat up while working. Repeated heating and cooling, make loose soderings to emerge.
Resolder all the suspected points, as loose solderings will be microscopic,a nd acnnot be detected very easly. We in the service field also will fist do this.
Usually vertical output section is composed of an IC related circuit. Solder all pins of that Ic first and feel the effect. If this does not help, desolder the IC out of the board, will be screwed on to a metal heatsink, go for the same type and number. Replacing the IC will solve your problem.
If you wants any more assistance, feel free to contact me through Fixya. OK.

Tv screen is black except for 1 horizontal line of color


The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

Picture on RCA TV shrinks to a horizontal line


Hello,
Sounds to me you have a cold solder joint ( loose solder connection ) on the printer circuit board around or on the vertical chip or on one of the vertical capacitors. You may also have a bad vertical chip or a bad vertical capacitor, but I doubt it since it did come and go. I'de get a soldering iron and some solder and touch up the connections. I will remind you that you need to always excersise saftey by making sure, before removing the back, unplug the TV from the wall, and use care not to come in contact with the large red wire going to the back of the picture tube as the picture tube can be turned off and still store lots of voltage ( up to 35,000 volts). Always stay safe and when soldering, use care not to run solder across places that will make a short.
Good Luck and I hope this helps

After a household power blips during bad weather, we have horizontal lines ....


Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .

Black screen, high pitched squeal


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.

Lines on screen


Can you take a picture of the screen and post it? It is not possible for both the horizontal and vertical stages to fail at the same time to produce a cross. A picture of the screen would help significantly.
