The usual is to factory reset the TV and test which has been done. if it still fails then it's back to the seller or maker depending on who the warranty is with.
I'd not tell them about the keyboard or other things. Stick to things the maker supplies. For the LG, only use the LG remote as the test device as that must work or they have a defect to correct.
Hi can anyone help me I have a strange problem with my tv when the tv is off the standard/sky remote will turn tv on and control tv for about 5 seconds then the tv stops responding to the remotes it still responds to the mobile app and a mini usb wireless mouse and keyboard I have I don't want to keep having to get my phone out to control my tv and the keyboard has limited functions for example I can't select input. Iv tried unplugging everything some time iv reset to factory settings nothing work.
Has anyone heard of this before any info would be appreciated
Thanks in advance
