I have a display problem with my philip uhd led 42put7590, within my warranty period the tv display has gone twice. The authorize service center people has done really bad job, it has gone blank for third time & i'm out of warranty period. Same bloody problem third time. I have no idea if this is manufacturing problem or vijay sales has con us. No way i can get the answers 50k gone in the drain.
