hi there, is the patterning like sparklies on the picture.??
if so the v up and v down need adjusting on the y sus board...
let the set warm up for roughly 30 mins then adjust as nescesry.....i found that i couldnt totaly get rid of them when the set was cold, so as the set warmed up they would disapear....lg said it wasnt a fault with the set just an ageing pdp pannel....
