SOURCE: TV has a thin horizontal line across the screen
intermintence in vertical IC deflection its a job for experienced tech need to look for that circuit and do fine job resolding that IC
SOURCE: TV: bright line across black screen for several hours.
vertical problem need to check for bad solder joints on vertical ic would be helpfull if we had the model number o f yur set. also could be bad capasistors in vertical section.
SOURCE: thin horizontal line across screen, no picture ,
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.
