Friends, even I had the issue of my TV set making an annoying noise when switched on. I complained this to the service center and to my luck I got a good technician, who tapped the wires properly with the Cathode Ray Tube. After this there is no issues with the annoying noise.
However, I do have issued with the S-Video out feature in the TV set. I am trying to connect my Lenovo Think Pad to my TV via S-Video out. I have connected the same laptop to my SHARP TV with success. It seems that no one seems to know if it works and how.
I waited for and unbelievable 4 to 5 months after the initial complaint made with the customer service dept. They kept on promising me one thing or the other. They at last promised me to offer a different model as they were not sure why S-Video out was not working for my TV Set. I denied as there are no other models in the marker which has the S-Video out feature. At last I figured it out myself and got the damn thing working.
