Ground loop problems and how to get rid of them
http://www.epanorama.net/documents/groundloop/index.html I have the group loop problem before when connecting the CABLE TV antenna cable. I bought a Jensen isolation transformer and the problem solved. So you found the ground noise, you may try to unplug the cable TV antenna to see whether the problem is come from therehttp://www.hififever.com/market/images/l_129_01.jpg Hi, William,
Would you please tell me where you bought the "Jensen isolation transformer" and its cost ?
Thanks! 海記, I bought it from eBay, but the shipping cost is big when you only purchase 1 unit. So I bought 2 units and having 1 unit left. So if you need it, I can give you to have a test before you pay for the cost (USD110/2=USD55) Hi, William,
Thank you for your "Jensen isolation transformer".
I just connected the transformer between the i-cable and TV.
The result is surprising good!
1.The picture is a bit improved. Clearer and sharper.
2.The sound is much more clear as well as sound effect, if any.
Although it is quite expensive, it is worth to have one.(?):roll:
Will you please call me on Monday so that we can complete the deal ?
Thank you very much! 海記, great to hear that! Is the hum sound problem solved as well? Hi, William,
In fact, there were only a few "hum" coming from the TV previously.
However, they still exist some times (less than before) especially when watching the football matches. Don't know the reasons...
Anyway, please call me when you are free; or;
would you please tell me your a/c by email (?) so that I can transfer the money into your a/c ?
Thank you very much! Hi, William,
Just received your message.
As the Chinese Lunar New Year is approaching, I will complete the transaction today. (about 6 p.m. :D )
Once again, thank you very much! Hi, William,
Payment transferred last night.
Please call me or email to me to confirm.
Thanks. Got your payment. Thx and Happy CNY!
