After assembling the kit only backlight working! Need help
Please post a picture of your assembly.
Maybe there’s an error in the soldering
Hi, i checked all pins , no short, no cold joints, all pins perfect. I check esr of capacitors all ok. Oscilograms from MCU perfect. Voltages perfect. What next???
Could you please a post a picture of IC1 and maybe the whole mainboard(without the LCD)
Microcontroller is Atmega328P-PU
I too am having the same problem of only the back light working. I have checked all joints, components, pins, etc. All checks out fine. IC 1 and the microcontroller are the same as the above post. Any feedback would be welcome.
