Faulty TV for spares LG TV 47LE8900 (Hanover BN2)

This is a large heavy flat screen TV which doesn't work on HDMI inputs but last time I checked worked on Freeview, I think it can be fixed with resoldering a chip or a new AV board type LG "EAX61742609 (4)", or this may work too - see video https://www.youtube.com/watch?v=8sslythR5HE
It would only suit an electronics enthusiast. It's a 2 person lift and I could help put it in your car
