We want to make it is not short circuit in the LCD panel that causes the Transistor to burnt out.
So i took some measurements with panel cables disconnected to ground and am getting 30 KOhm, 50 KOhm and 80 Ohms on the emitter (leg by the R1104). With the panel cables hooked up, there isn't much change.
