Check and replace the vertical scan output IC. Check related capacitors, and solder terminals at the vertical scan output section circuit for any loose soldering. Check the voltages at the vertical scan output IC. Refer its circuit diagram [schematic] for more details. If you wish to get some details; check the site linked here. Pull up older posts.

My sony tv has vartical problem, when i start tv a white line is coming on the top and vartical screen is small. i check all dry solder. the vartical ic is LA7830. help me.


Check the electrolytic capacitors near this IC.. one or more of them may have either shorted or it's value may have changed signifcantly. Happens on olders sets .. they dry up due to heat if they are near a heat source like an transistor or IC mounted on a heat sync. Please give me the make and model of the TV.. there may be some known issues that I can look up for you. Also I need to know if the problem happend slowly or all of a sudden, hows the sound etc... give me as much information as you can.
