@idahosabar55362 can you explain this "glitching multi color visual and it normalize's" a bit better. The term glitching is not very descriptive to me :-) Your TV is a LG Plasma TV 42PC7RV-TA? Can you post some images of what your screen shows when it is glitching? Does the power LED give you a blink pattern?在已经存在的问题里加入图片
