The v10 still does that clicking/ pinging sound every so often. I went to the shop where I bought the set and their demo v10 does the same thing. They only just noticed it despite having the set for 2 weeks, but from the testing they did with it this morning theirs only makes that same noise within about 1-2 minutes after switching it off, where as mine does it regardless of whether or not it has been on, and is not limited to once or twice but throughout the day.
They suggested it might be the relay? And they will contact the manufacturers.
Could any other v10 plasma owners please check on theirs - I don't mean sit by the tv for hours until it does it, but if you could watch out for it, say for 5 minutes after turning it off, and listen out for it if you're in the living room reading/ relaxing and the tv's off, that would be great.
Thanks
