White Screen !!! Variant # 8. Solved

[Maury]

Hello everyone waiting for someone to have the answer of this problem.


I have the screen number 8 that is in the wiki and I followed the steps to change the cable to 5 V, however after doing so I received a totally white screen ..

After searching for a solution in the forum I did not find the answer and made the decision to make several changes in the configuration ..

Connect the 5v cable to the place that demonstrates the modification of the wiki and came out the white screen.
 
leave everything connected and simply disconnect the white cable from the RP, I had no signal.

Leave all the same and connect the white wire and disconnect the yellow wire, on the RP, No signal.

After not having luck, disconnect the jump cable and connect it directly to pin number 3 as indicated by the wiki, and after this step the screen is as shown in the photos.

I can only see the menu for the screen but it's very hard to see.. other that that NONE.


I hope and someone has ideas on how to solve this.

Thank you.

I'm struggling to load your pics while on my phone but I only ever connect one wire, white or yellow.
The other thing to check is the ribbon cable, make sure it is pushed in all the way and also the right way around.

It's where I'm confused a bit, in the video of wermy it shows the YELLOW and WHITE connected to the RP and I understand that those 2 cables are for video and we only need one but on the guide it showed both connected.

Once you get a chance, please check the pictures so you can get a better idea of this issue.


Thank you so much for sharing this info..

Your ribbon cable from your screen looks crooked. This is the typical cause of a white screen. Reseat the cable and try again. As far as yellow and white pins you only need one. The other in wermys guide is grounded so isn't doing anything. So just pick one or the other.
