70D motherboard replacement

[Stigliano]

Google translator:


Due to a fall, I needed subistituir my motherboard. Buy one at aliexpress. I made the switch. 2 problems appear. 1 - Auto focus deregulated. 2 Built-in flash does not work. The focus makes sense to be in trouble, but the flash I do not know what can be. A friend also made the switch, the same model, and also the flash did not work. Is there any regulation by software to solve it? Anybody know?
When I repeatedly testing the flash, for a moment or two, he acendou. Not anymore.

Devido a uma queda, precisei subistituir minha placa mãe. Compra uma pelo aliexpress. Fiz a troca. 2 problemas aparecerem. 1 - Auto focus desregulado. 2 Flash interno não funciona. O foco faz sentido estar com problema, mas o flash eu não sei o que pode ser. Uma amiga tambem fez a troca, do mesmo modelo, e o flash tambem não funcionou. Existe alguma regulagem por software que resolva isso? Alguem sabe?
Quando fiquei testando repetidamente o flash, por um ou dois momentos, ele acendou. Agora não mais.
Abraço

I have no experience with this, but there are a lot of calibration parameters in the firmware. That's why I'm usually hesitant about reflashing the ROM with the one from another camera.

If you have an older copy of your ROM, I can attempt to flash it on your new mainboard. Not sure if it's of any help, and I've never did that on 70D, but since you are not afraid of swapping the mainboard, we can probably take a risk.

The 70D also has a serial flash, but I'm not sure whether calibration parameters are there or not. Most cameras also have an EEPROM, which I believe it may contain the calibration parameters for autofocus. However, the install program does not do backups for them (it probably should).

It will not be helpful, but let us understand that calibration is needed - https://www.spt.info/index.php/service-adjustment-software/14-uncategorised/36-main-pcb-1

Thanks for the answer. Recording a new ROM to be physically, is not it? You need to send the card to you? If I am in Brazil, would not send for a autoizada? I did not make any adjustment. I received the PCBs replaces. I made the adjustment menu pixel dead. Overall, it works well. With the ML DoT Tune made a focus of regulation, but not this good yet. It would be highly recommended to send an authorized? hug

Obrigado pela resposta. A gravação de uma nova ROM precisa ser fisicamente, não é? precisaria enviar a placa para você? No caso estou no Brasil, não seria melhor enviar para uma autoizada? Eu não fiz nenhum ajuste. Recebi a PCB, substitui. Fiz regulagem de pelo menu os pixel mortos. No geral, funciona bem. Com o ML DoT Tune fiz uma regulagem do foco, mas não esta boa ainda. Seria muito recomendado enviar para uma autorizada? Abraço

In my case until it initialized. But thanks for the indication of the site. I'm reading all about! hug
