Screen not working

[T DogZ]

I checked the continuity between the pi and the pcb. I also updated to the newest minty pi image. The screen and the pi work but the screen just shows white. Could someone please help me on this. Thanks.

Could you post pictures of your soldering? Also, you have solid continuity on all of your screen GPIO ports? Which version of the PCB Combo are you using?

I am using the newest PCB and I do have solid continuity.

Test continuity from the test pads on the bottom of the ribbon connector to the LCD board test pads.

Could you show a picture of that.Thanks

When you have the ribbon that connects the LCD board and the button PCB, you can test continuity from these LCD pads to the test pads on the button PCB

I have the same problem and i tested the pads under the ribbon connector and found that VCC and SCL did not have connection. Is this something i can fix?

Always good practice to re flow the joints to see if you can get continuity on those specific points. If you cannot get continuity you can add a jumper wire from the pi's GPIO's to the test pads on the main PCB.
