42LG7000-ZA hit by power cut

[scooby-doo]

Hi

I am sure I have seen somewhere that LG's dont like Lightining or powercuts....Well Ihave this model that suffered a powercut...now all that happens is the front led lights up...it is very dim and slowly goes dimmer then brightens up again, then repeats...it is not in any sequence it just has a mind of its own.

When these things have an electric surge what does it normally take out??

Cheers for any help
