Question about Sony KV-40XBR700 40" TV
If the display seems normal when present, you may have what is called a 'cold solder joint,' possibly in the area of the horizontal power supply.
This can be caused by normal heating and cooling of a particular spot on the circuit board that finally fractures the solder and making the joint thermally sensitive.
Most component failures, even when intermittant, would affect the display in some obvious way such as distortion, contrast, brightness, etc.
