Check all LCD connection to main board for continuity .

LCD is broken ( cracked)

Latest firmware is 113-13801-041 as i just got new DSO138

Is this Fake or real ???

What is different at LED Pin 19 ???

How can i get BOX ????

Here is simple solution If MCU is working Green LED is blinks twice then do following steps. 1) check voltage on AV+ 5v, +3.3v, +5v should be + - 0.3 OK, Don't worry about AV- for now.. 2) Solder Pin on 40 Pin connector on both LCD and on board ( keep soldering tip for 3 sec on all joint one by one)...

Hi just got yesterday assembled it , Same thing as Other complain . White Screen and no -ve voltage all other are good , How to test to find whats wrong????
