Every now n then,in my 27" sony trinitron telivision, there is this loud "shhhhhhh" sound in the backround of the normal sound. I can still hear what the people on tv are saying, but that sound in the backround is sooo annoying. I dont want to have to take it in to the shop and have them carge me 300$. I cant really aford that. is there anything you can do to help. thanx

Good Morning, Blake:
From the description, it would most likely be a function of the AGC (automatic gain control). The signal must be regulated within the electronics so that the circuits can perform normally. If a signal is too strong, the Automatic Gain Control (AGC) kicks in and reduces it electronically.
The AGC circuit, however, has a limited range of operation. If, perchance, the signal being fed to the antenna jack on the set is high enough, you could be exceeding the AGC range. This causes hiss, buzz, etc in the sound.
You might try padding the signal down a little at the antenna to see if it clears it. You can pick up a 5 dB pad at Radio Shack or you can put a common 2-way splitter in the line (3 dB) loss.

Just a wanna know... Are you on a cable box or satelite receiver that you turn the TV set volume up and then use the remote for the satelite to adjust the volume?
