CSL screen problems

Post by eggbowl » Sat Nov 30, 2019 8:33 pm

I was setting up my CSL, and I think something is wrong with my screen. I've tried disconnecting the ribbon and reattaching it a few times but it doesn't change it. The screen looks tinted blue. My camera didn't pick it up the best but it looks different from the picture in the guide definitely. Is my screen broken? If it is can I buy a replacement?

Could you show a picture in tester mode with all those colour bars on the screen please?

Re-work to solder on this pin, note that the picture shows the side of the board that has the Pi on! :

Make sure to rework the solder on both sides of the board on that pin in the top corner

Hm looks alright, could you get some acetone or Isopropyl alcohol to clean the flux off the soldered contacts?

Also when ON and the white screen thing is showing, if you press on the pi of wiggle it slightly does it change the image?

Equally if you press the LCD FPC ribbon in/out etc does that change the image?

I cleaned it with alcohol, but I don't see any difference. The image is flickery, but from what I can tell pressing on the pi isn't changing it. Fiddling with the ribbon cable changes it a little.

At this point i'm not sure, i'd need to see it to work out what is wrong, would you be able to send me an email and i'll let you know the details and we'll get it sorted that way
