I just blew on and reseated the 3 ribbon connections and reassembled. Then it worked. I'll check tomorrow if it is still working well. Thanks for all the help and info, I'm sure someone else with this problem will find this thread now. I do just have one query though, if this was caused by 2 adjacent ribbon lines shorting, would this happen by manipulating the ribbons and trying to recreate this short after booting, or is this line just polled on startup and ignored subsequently? It seemed a bit odd that when I first powered up, the boot display was the right way round, but as soon as it got to the main program screen it flipped and stayed flipped. Cheers. |

Do not assume web search engines will find the one thread where a solution was discovered – especially since you didn't even initially post that it got fixed, just posted an image showing that it is now fixed. No web search engine is able to tell that this particular thread contains fixes. To be blunt, you owe it to those who helped you, to pass it forwards. --- Quote from: Audiorepair on October 22, 2024, 05:52:48 pm ---if this was caused by 2 adjacent ribbon lines shorting, would this happen by manipulating the ribbons and trying to recreate this short after booting, or is this line just polled on startup and ignored subsequently? --- End quote --- It is typically sampled at the start of every frame, once every display refresh, so about 60 times a second. It is absolutely possible to recreate the mirroring by connecting pins 35 and 36 using a suitable resistor. (A strong direct short, say using a screwdriver to poke at the gap between those pins on the daughter card, may create a direct short between the digital VCC and GND, and damage something.) It's just that at 0.5mm pitch, it's beyond my own finger dexterity; if I were to try and do that, I bet something would go Pop! and release the magic smoke... |

Then I posted again. --- End quote --- I did not mean it as an admonishment/criticism/negative, or to annoy you, but more as an observation and general suggestion on maximizing the usefulness of such solutions – including to future oneself. I am blunt and direct, and have no social skills to speak of. I may appear as someone very knowledgeable, but in fact, I only have good search/reading skills, and have to spend a lot of effort getting my output in even a roughly acceptable state. Very often, I fail to consider the social subtext. :-[ For me, it is extremely important that solutions found are reported and made available to others suffering from the same problem. This is what makes it worth the effort of research and answering: it must help more than just one person asking. The best case, in my opinion, is when the help-ee posts a summary describing the issue and the solution as they understand it (a quick single paragraph), for maximum search engine discoverability; and in turn helps someone else later on. If you want to know the basis and reasoning of this, see the why writing style and grammar matters in posts in the Beginner section. You could say this is my small way of making the world a better place. A tiny way, microscopic, sure; but it is still better than nothing. All that is necessary for evil to prevail, is for good people to do nothing. |

@Nominal not to start an debate While i understand you're statements, the OP is not under any obligation(s) to post elsewhere to provide a solution, for now if it work ... YOU can write to other forums ... because in a sense you'll be responsible in a way of the posted threads ... And if you do google search(s) eevblog will come out as an answer .. |
