Good day All,

Ran into the white screen issue with my mintyPi (v2.0 board, stock mintyPi image). This was after a couple of weeks use with no issues. During gameplay the screen suddenly cut to white. I still got sound and was able to use the hotkey to safely shut down the system. Each time I restarted the system afterwards, it would always cut to white at some point between the Retropie logo and the mintyPi splash screen. Sound still plays and the hotkeys still worked, so the system is booting up fully.

Here's what I've tried so far:

• Hooked it up to HDMI. Everything seems to function normally.
• Tested continuity between the Pi and the PCB. All okay.
• Tested continuity between the PCB and the LCD screen board. All okay.
• Tested continuity between the Pi and the LCD screen board. All okay.
• Checked voltage across the LCD screen's VCC and GND. I'm getting 3.28V while running off of the battery.
• Swapped the ribbon cable with a new one. No change.

Here's a picture of the soldering for reference: The only other recommended solution I've come across was to add solder to the ribbon connector pins on the PCB and LCD screen. This was a daunting project for my first soldering job. Before I break out the iron again, is there anything else I can try to resolve the issue?

Any feedback would be appreciated. Thanks.

check the lcd ribbon itself for damage or maybe a weak solder joint, the addition of some extra solder to the ribbon connector socket pins is a good thing to try too.

Hey Helder. Thanks for the quick reply.

After adding more solder to the screen and PCB ribbon connector pins, and swapping out the old ribbon cable with a spare, the screen got all the way to the emulation station menu before cutting out to white again.

I swapped the screen with a brand new one from a second mintyPi kit and it seems to be holding out with no issue, so the problem may lie with the original screen.

Here's a picture of the original screen's connectors for reference: Just to clarify, should the solder be added to the 18 pin ribbon, or the 10 pin connector?

Thanks again.

10 pin connector, the 18pin looks fine but doesn't hurt to reflow it.
