I have a Sharp Aquos LC32D62U 1080p LCD TV that I bought about 2 years ago and I have unresolved audio sync issues. I had a Sharp technician come out during the warranty period and he replaced a main board in the TV, but it really didn't make any difference. The audio is occasionally in sync, but more often than not the sound is ahead of the video regardless of the input source. I experience the same problem with HDMI, component, composite, and RF inputs so it seems to be an overall problem with the TV itself.
I'm at the point now where I'm considering buying a new LCD to replace this one, but that feels like throwing money away when this TV works perfectly fine with the exception of the audio sync. Has anyone else experienced a similar problem with their LCD TV and were you able to resolve it? I have noise reduction and all other video enhancements off, so that shouldn't be an issue. Are there other settings that I should check? What causes the TV to be in sync and then go out of sync, when the same sources connected to other TV's are perfectly in sync? If anyone has any advice, I would greatly appreciate it!
