TV is only 3 yrs old. Hasn't been moved in 3yrs. Ok untill now. Maybe a board? (i hope) I removed the back, checked fuses with ohm meter,all OK.

Display IC seems to have gone. It will be a replaceable module. Only you have to figure out which one it is. Such thing happen in electronics. Look for any burnt or bulged IC.

"Popped"? That sounds like a serious issue that is going to require a warranty repair or a professional TV repair person to address.
