The TV has become very sluggish when responding to the remote in the last few days. I've changed batteries and have also bought a new remote, thinking the kids had damaged it somehow. However, I still have the same problems. Basically, you can be pressing a button and nothing will happen for a few presses, then it might work for one or more presses. Sometimes, something might work first time but then stop - eg, typing in channel 101 I could have trouble getting any or all digits in or it might work straight off. It could be a coincidence (have a feeling it isn't) but the TV recently updated the firmware to 05.30.25 possibly straight before the problem started to happen. No joy from the LG online support and I can't downgrade the firmware to the previous one to test as LG don't allow that. Any ideas / suggestions gratefully received.
