Hello, I'm Shahid. Sorry to hear that you're having trouble with this but I'll do my best to help.

- Are the lines vertical/ top to bottom on entire screen?
- Is there any graphics/ menu options show up when press menu button on TV or its remote?


Customer: replied 1 month ago.

Expert:  Shahid replied 1 month ago.

OK, do the lines go away when tap on RCA connector area?

Customer: replied 1 month ago.
no. however i just noticed that the lines are mostly when i "no signal' is displaying. when i start up the device i have plugged into the hdmi this is how the color is shown in the picture i attached
Expert:  Shahid replied 1 month ago.

OK, it seems connectors might be misaligned or their connections are clogged. Please replug/ reconnect all the connectors on main board of TV, also do the same with t-con board (very carefully), reconnect LVDS cable (falt ribbon cable) runs between t-con and main board of TV and check the result.

If problem persist then you would need to swap main board of TV to fix the problem because main board has few surface mount chips and any of those chips has got dry solder/ bad joint issue which is causing the lines and green tinted image on screen. Please reply back with the result and if problem resolved then a positive rating to answer would be highly appreciated.
