There is some urban rumor going around but it's not the Voltage.
Did you call it in and ask?
Also, remove from service before it damages other boards.
Two days ago our Samsung 46" (LCD LN460A580P6FS - $1200) started making this clicking sound when we went to turn it ON. When you hit the ON button it will click a few dozen times before we finally get sound and a picture.
After reviewing other CNET/Samsung threads I'm thinking this sounds like a known issue with another big screen Samsung LCDs (e.g. LNT4665F) where the TV is turning itself ON and OFF.
Could we be experiencing the same issue as was reported in the other threads? Something related to the manufacture's capacitors not having sufficient voltage for the tv? If so, what is Samsung's current response to this problem?
We're hoping this too is simply a capacitor issue, and as indicated in the 2009 thread, Samsung will step forward and remedy the issue. This was our very first BIG SCREEN purchase... ever! The B*st B*y rep assured us that if we stuck to one of the three "S" manufactures (Samsung, Son* or Shar*)... we couldn't go wrong! Thus far, we've really enjoyed our purchase! : )
I look forward to your feedback.
