Greetings all: I have a Sharp TV model 27rs100 which has an intermittant audio problem. Sometimes the audio is good, sometimes bad. Touch/tapping almost anywhere on the board will have some effect in the audio. Order the SAW filter, replaced it, now permanant hissing as if no channel. The picture is good. In the service mode there is steady hissing, the picture/channel is Not properly tuned. The service manual shows no AFT adjustment that I see. Any suggestions? Do you know the proceedure for an AFT alignment? Thank you for your time.
