downgrade or upgrade firmware will not correct any value you changed at service menu...

yours red wire you add it make overload to cut off picture function which caused the Gama IC ( U2 ) over clocked.
remove the red wire and fed the tv with signal and show here how the screen look like

i removed the red wire but there is horizontal lines and a blarry screen saver.

In the service you need to change the LVDS format from JEIDA to VESA or vice versa from VESA to JEIDA.

i removed the red wire but there is horizontal lines and a blarry screen saver.

the screen say no program... so choice INPUT HDMI. and fed it with external HDMI signal so we can see the picture how its look like

THIS IS THE POSITION OF THE PICTURE
