All Flat TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times reseating the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em.

SOURCE: hello,we bought our first sony
The problem going away after a while indicates that you are just another victim of capacitor plague, on the main audio video board. There are cylindrical components known as capacitors on the board which rapidly charge and discharge. If they are faulty then, it would take longer than usual to reach the optimum capacitance value. Replacing these things requires prior experience in working on PCBs, especially soldering. If you have these skills let me know and I will help you fix this. Otherwise just get me your zipcode and I will get you a list of techs in your area.
