im running out of ideas one last test i can think of is on the tcon board you will see some round gold colored test pads with writing by the sides of them start with the ones that start with a letter v test the voltage and let us know what the pcb marking is IE VIN IN 12V VGA 1 12V ETC ETC

Did you also check if any component in the TCON is hot?
Or use a hdmi and check if you have any sound. If you do have sound but no picture then TCON(most likely) /mainboard is bad.
If you don't have sound then you have a firmware problem.Last edited by ducky29; 11-26-2018, 05:39 AM.
