Cytron Technical Forum

I am trying to build a FM radio based on the PR-31. But somehow it does not work. There is no display on the LCD. Can you help me with this. I thank you in advance for your help

Hi..

Is the LCD totally doesn't show anything or is there any black row showing? Did u try to turn the preset to adjust the contrast?
Can you capture a photo of the hardware, top and bottom. Might get some problem there.

Thanks joliza...actually i figure out the problem. The cause of the problem was due to the affected PIC. Once i try to program it using a new PIC, it works perfectly. There is display on the LCD and i can listen to the music. Thanks again joliza.
