@briandillon1980 commonly horizontal lines across the screen are issues with the panel and in general can't be fixed by us DIY'ers. Since yours (if I understand you right) only go 2/3rds across the screen it is possible that this is a memory issue. That would require a new mainboard (or a good main board reflow ;-) Of course, you also want to check your LVDS cables for corrosion tears etc. The T-con board will not be an issue
