Hi everyone, few days ago I've replaced my Bravia 46 with a brand new LCD panel due to clouding issue "though it still remains on the new panel", but now I've discovered a new issue. I hear a series of clicking or popping sound coming from the internal backside when I first turn on the tv and also when turning off. The sound last about 15-20 seconds though it never happens during watching. The sony repairment guy told me that it's normal for a new panel to make that sound sometimes and should last about a week's time. Well, granted it's only the 3rd day but just want to know does it happen to anyone else here? Should I trust sony's advice? Thanks for any inputs.
