please help... Grid-like pattern in the background of my screen on my Toshiba 27A43 CRT TV ?
I know that it is not visible in the photo I've attached, but I need some help .. I am new to CRT TV's. This one was my grandparents, and I remember spending many long hours watching and playing video games on this, back in the day. I just recently retrieved it from the family storage unit 100 miles away from my home.
For some reason, there is a grid in the background of the TV picture on the screen. My mother said that she may have messed something up on the service menu. I am just so lost, and feeling so defeated. Nothing online is showing me any definitive way to fix this...
