Re: A1708 (820-00840) power issue

Hi Piernov,

Thanks for the reply.
I tried to replace both by C00 but I still don't have the 20V at PPDCIN_G3H. I have 5.2V.
I look for I2C communication between U3100/U3200 and the SMC and I can see both I2C acknowledge so I think both circuits seems to work correctly.
I'm confused between B03 and C00 because I read that this board need B03 here: [url]https://boards.rossmanngroup.com/forum/board-repair-troubleshooting/47964-820-00923-a-not-turning-on[/url]
and the inverse here: [url]https://store.rossmanngroup.com/index.php/za2-cd3215c00.html[/url]...

Re: A1708 (820-00840) power issue

Hi everyone,
I'm facing a power supply issue on a 820-00840 motherboard. It seems that someone was visiting this board before me. U3100 and U3200 are respectively a CD3215B03 and CD3215C00. I know that both chip must be identical. Does someone know what is the correct reference value?
Best regards,
Fabrice
