Called Sy based on recommendation from LG. Had plasma with horizontal purple lines. "Tech" arrived 2 hours late. Could not diagnose the TV on his own, unskilled and not a true "tech". Said all they usually do is take pictures with iPhone and send to tech support for diagnosis! All this for $87.00 service call charge! We could have done that on our own for free. They claim to be #1 in TV repair, but that is ridiculous! Maybe back in the 80's. Then when they sent us the quote for repair they said it would be almost $1200 for a new panel. My opinion is that they tried to take advantage of me. I called another repair firm and the issue was de-soldered inductor on the Y-axis board. Total charge $110 repaired and running again within a couple of hours and didn't have to take pictures and comeback!
So disappointed.
Called service manager and didn't seem to have a care in the world, lesson learned.
