Hi,

Initially I would suspect a problem in the Vertical section of the TV. This could either be the capacitor or the IC itself. In some instances, there are no component failures but rather cold solder joints.

Based on your post/description of :...Once in awhile picture returns to normal...", I am more inclined to think that it is a case of cold solder. which can easily be corrected by reapplying heat on the IC pins or the other associated/nearby components with the use of a soldering iron. Care must be exercised since TV units still pack high voltages even when off and unplug.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Sony Trinitron kv32fs16 picture shrinks


You have a bad solder connection in the vertical circuit. This will require you to resolder these bad connections before it blows out the vertical output IC or other parts in the circuit. Do this ASAP before you make a small repair into a large one. If you have no solid state printed circuit board experience, please play it safe and take the set into a pro to do this for you. Good Luck

Picture Shortens, Converges, eventually the set shuts off - $50 for Correct Solution


Open the TV amd turn it on in a position you can see the picture, possibly through a mirror. Now gently tap all of the metal heat sinks on the circuit board until you find the one that is sensitive it will have a small chip mounted vertically on it, with probably like 7-10 pins. The number on the chip will most likely be an "LA****" number. Now turn the circuit board (UNPLUG FIRST) over and resolder the pins. This is your problem 99% of the time. Be very careful there is High Voltage inside this TV.
