Hi,
We have a 2.8 in screen and a 3.5 in screen. The 2.8 is working fine and so did the 3.5 when we first received it. Currently the 3.5 in only turns white when powered.
We have followed the forums and have the ready-to-go image for the TFT kernel.
Any other suggestions?
THanks

Post a photo showing the back of the PCB where the flex cable fits into the connector. 800x600 images usually work best.

Re: TFT Screen White only
Hello,
It does look like that connector might be the culprit.
1. the surface mount connector slid a bit in re-flow.
2. I'm not sure if the ribbon is completely connected at the top (pin 1)
Circled black part is free floating where the other side is connected at point 2.
Is there something I can do to get this working?
Thanks

Re: TFT Screen White only
Checking with my meter pin 1 was not connected. Fortunately I was able to pull out the black piece on the connector that clamps the ribbon and reset it in there.
Re-checking with the ohm meter pin 1 is now connected. Plugged the screen back into the pi and still white screen. Replace with new screen (aslo 3.5) works just fine.
I have attached two pictures. One showing the bad screen powered on. The second showing the new screen powered on.
Thanks
