Thanks a bunch mag for your reply,,,,,,,,,,,,,my instant reaction was that may be it has got something to do with operational settings and was uselessly playing with the remote with no success,,,voltage i must admit is around 170 at my place which i didnt checked from the AC rather on UPS as its input is 170 these days,,,ill try a stablizer to check,,if that can be an issue,apart from that will get some technican as m a layman in technical terms,,,,
