• ghostbusters! actually, you may need to call a repairman. i was thinking it might be the cold solder points, but that doesnt explain why the tv comes back on. this may be a case of short, periodic power outages. if you plugged your tv into a surge protector strip, try connecting the set directly to the wall outlet instead. or if your tv is old, it could be that the welds have stopped conducing properly (thats why when you smack the tv it comes back on) these weldings may need to be resoldered. lastly check and see if the auto sleep timer on/off has been turned on. if no to all of these, call the fixit company.
  • One cause may be (if you use a spray cleaner on the glass face, some runs down to the buttons and the slow corrosion may begin to partially conduct.
