Tried the backlight tester and the screen stays on with an image
Also noticed on the main board bga has loads of dried flux possibly someone has tried heating the bga so tried gently heating up the main bga but now backlights don't flash on start up

Re: LG 47lb580v

I've observed that LG LCD and LED TVs suffer from BGA issues that are cured sometimes with re-heating. I am contemplating not recommending LGs to my friends, family and customers. Oh, I almost forgot...They suffer from Backlight failure frequently, too.
