AC screen being straight white

Post by Doc105 » Thu Feb 28, 2019 11:45 am

Out of nowhere I powered up my pi and the screen turned on but was just blank white, I tried a different screen and the same thing happened. The green led on the pi was working so I really don’t know what’s going on.

please show your wiring.....

its difficult to know without seeing what you've got going on....

but...
it could be that your video (AV) cable isnt connected properly (or to the right point/location on the Pi0)

i'm not 100% certain if that screen requires a 5V mod or not.....
that could be one of the issues, but if you were using this before and it worked... then it might not need a mod


another thing that doesn't look so good is your solder work around this section....
(really need a decent connection for the AV)

I'm not sure if that's flux or solder, but it can/should be cleaned up


I would also try powering the screen on its own (still having the AV connected to the Pi0)
this would only really be worth doing once you've determined that the screen can run off 5V and doesn't require any mods
