the video card maybe is burning out

Answer 2

There are several things that could be causing your problem.  It could be the Flyback transformer, horizontal output transistor, low voltage power supply feeding the video circuits or any number of failing components in the high voltage circuit.  It could be costly to repair now days. You could check a reputable repair shop and get an estimate.   If financially capable, you should consider a new Sony TV.
