Have this TV which turns the backlights on but shows no picture. Have quickly checked voltages, may have missed some on the power supply and main but overall it looks ok. Responds to buttons, backlight brightness changes if i press the "Home" button.
Tcon fuse is good. Tcon is generating all drive voltages for the panel. Scoped some of the LVDS pins on the Tcon side, it looks to me like it's getting data from the mainboard.
Reflowed both BGAs on the Tcon, although the board underside did not show any signs of them getting hot. No change.
Would this pretty much guarantee the Tcon is bad, or should i dig deeper into the mainboard as well?
