Very thin black vertical line moving across tv screen left to right on tv

The screen voltage to the picture tube is more than normal. Adjust it by the help of screen pot-meter integrated with Line Output Transformer. Visit the site named 'Electro-help' for more details. Check this link and select the site named above. View it in 'Flip card' option, which can be selected from the drop down box menu at the left top corner or the display window. It will make search easy.

JVC picture turns into a single line in middle of screen.

This is caused due to random falure of vertical scan circuits. It generally is caused by dried out capacitors or bad driver IC. Unfortunately it will get worse. If you fail to turn the TV off quickly you will burn a permenant horizontal line on the tube. Trip to the repair shop I am afraid.

When the TV is first turned on, thin white lines appear horizontally across the top 4" of the screen. The lines go through the picture, distorting it. After the TV is on for a few minutes, the depth...

On this particular model there is one capacitor from the video process IC (jungle IC) that supplies the Vertical pulse that shoul be changed.
This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical. Be sure to vote/rate me if this helped Thanks!

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

Black horizontal lines across bottom 1/3 of screen

This is due to vertical section failure. Change the vertical supply rectifier diode and supply filters. Then check zener diode leakage in pumpup circuit section. Also check any electrolytic capacitors leakage in vertical section. If it is old model tv change vertical height, vertical lenearity presets also. I hope given details useful to you.

36" CRT Toshiba has that vertical issue mentioned on here a bit

Your problem is most likely caused by a cold solder joint in the vertical circuit. Normally this is easy to find and correct. The problem will only get worse over time, but not likely for more damage to occur.
