Hello none of the HDMI ports work ,comes up as no signal.Is there an easy fix or do I have to replace the main AV board.Any help appreciated.

Hi old chap,

Not much you can do with HDMI ports. They're not my favourite type of connector, can be wiped out with the slightest electrical disturbance. Best to replace the main board.

Not terribly familiar with this chassis, but if it uses separate NVM's for each input these can be reprogrammed,   but you need good nvm data, when I get home I will go on LG site and check manual.
