Meron po akong concern sa 42PV8 ko, bago lang pero parang may waves na gumagalaw pababa kahit manood ako ng TV or MKV movies..Im sure hindi to normal...pero ano kaya nangyari dito??
sir, are you using an avr? from how you describe it kase, waves might mean power fluctuations... or maybe something else.... have you tried plugging it on a different outlet?
try to isolate the problem first, you may want to remove all gadgets near your pv8 and just play it on its own, or maybe try to use a different cable source (e.g. another outlet perhaps) if problem still persists after all this, then contact mo na kung saan mo nabili, there might be something wrong with it...
well, anyways, good luck!
