Hi Brains Trust. 512k bongs and the screen displays expected startup for about a second then black. Anyone experienced this and can head me in the direction of possible culprit/s Cheers |

Did you do re-flow or re-solder anything? Even if the harness has never been removed, it can still result in cracked joints over time. |

Thanks have checked this It‘s almost impossible to see the cracks sometimes. Best reflow anyway 🙂 |
