Need help with screen!

Post by Lambchop8 » Mon Jun 12, 2017 11:50 am

I have a BW 3.5 in TFT LCD screen. My zero works with my tv and hdmi. Below are the picture of what I did from what I learned on the forum. My screen is on but nothing happens. I think I wired t correctly. I am in need of help!

Can you try changing the yellow wire to the other pin (one on the left)?

EDIT : Also what are the pins K6 on the video board. Have you checked the wiring? If there is text on the other side of the video board a photo might help

Doesn't look right to me. Usually wire the 5v to main board input then put a jumper over to the Regulator.

Also, not familiar with this board but looks like your 5v is going to wrong regulator?? Assuming its the 8 pin one...

I would move 5v back to main input and test with 12v power supply to ensure screen actually works.

If so, then add the jumper to correct regulator but be sure to then use 5v else you'll blow it :)
