Hi David sir,
I already mentioned above LCD problem,you remember that sir,We are Run the LCD program again and check it,the program were Run correctly so we use the stamp light and saw the screen that is blurred so we think the backlight was problem and check power level we found they derive TP18=0Volt(led-) and TP19=5V(led+) respectively.Is correct sir because we give the Input also 5V(i represented in attachment) otherwise how much volt in TP18&19Image may be NSFW.
