LG 50LA6970 Audio Issues

[tvfixer007]

I was using this TV as a computer monitor with HDMI Audio which sounded great without any issues. I decided to give this TV to my mom and when I hooked it up to the Samsung cable box the audio had a high pitched sound and cut out every 5 - 30 seconds. The original Sanyo Plasma TV that was hooked up to the same HDMI port had never experienced this issue. The LG 50LA6970 never had any issues on my PC.

I tried to google search this problem but I don't actually see any posts that are exactly the same. What could be wrong?

Try a few different HDMI cables, also try connecting different sources to the same device, then try different HDMI ports. I've seen sets that are extra sensitive to what type of source you have it connected to and what quality and length etc of HDMI cable used.Try resetting the the different devices or turning them off and on after changing HDMI cable.
If both of those sets worked before trying to switch them it sure sounds like either a bad HDMI cable or bad HDMI port , or they needed to be paired probably to each source or they don't like the HDMI cables you're trying to use.

Thanks for your reply. I will have to buy more HDMI cables. I hooked the TV back up to my computer and tested the HDMI ports and all of them work.

Seems like the cable box doesn't like that cable with the LG TV, but the cable works perfectly on the Sanyo Plasma TV. Rebooting the devices had no affect.
