i recently bought the Au7100 50" model tv, but looks liek there is a problem as it takes time to change after pressing any button on the remote. like i press on the home button then i may need to wait atleast 10-15 seconds for it to happen on TV...so is there is a problem or its normal with this model. the response is quite slow whenever i press any button on remote and the effect on tv.
Did you get two remotes with your TV? If so, is it the same response time for both? Does the same thing happen even if the remote is pointed a few inches away at the TV's power light?
And just to check: have you tried different (new) batteries in the remote; and is there anything that could be possibly obstructing the signal between the remote and the remote sensor on the TV (e.g. a speaker or soundbar)?
