Did you try inserting the LVDS cable into the TCON a couple times? That's that ribbon cable/wire that has that special connection to the main board and delivers the picture signal to the TV. That tcon is always found in the top or bottom center. If you unplug it too, on some models the LG TVs will cycle colors on the screen. That would tell you the TCON is ok. At 22 inches, you may find your Tcon integrated into the panel and not a separate part like in the 32 to 70 inch TV sets
