A single set of horizontal lines could indicate damage, a graphics system failure, or loose internal video cables. Broken signals from cables or graphics hardware creates impurities in reproducing an image on an LCD screen, conditions that often manifest in the form of vertical or horizontal lines of color. https://itstillworks.com/causes-horizontal-lines-lcd-panel-37988.html

I hate to give you bad news but I believe this will be a panel issue and it's not going to be fixable. You can try a different tcon board but I don't think it will help

i have the same problem with the gray lines but mine blinks really fast and its extremely annoying. I think the problem is the tv you probably hooked up your snes to. I dont you which tv you hooked it up to but ive heard that if you use like a modernish tv, it will create those gray lines and the blinking so you should hook it up to an older tv. i dont no if this is true because i didnt switch my tv YET but hopefully, it will work better with an older tv. hope this helps ^_^

if u see them on lcd and final output also have these grey streaks then ur problem might be this u can call canon for free repairs but first try to clean ur camera head with head cleaning cassette and see if it helps otherwise call them see link

The horizontal sweep signal to the yoke is bad. Since other problems exist, the problem may be in the IHVT HI voltage transformer area. Check for bad solder around the IHVT pins and yoke plug. I hope this helps. Lee http://www.CrazyComputers.com
