Hi, as requested the other side of the board. [ATTACH]n3183079[/ATTACH]...

HI [USER="488280"]mariukonie[/USER]. I have the same board on my bench and can help you. And I would also need your help. Could you please check the markings on U1 (primary controller chip). Mine is too damaged to figure out what it was (unless I go forensic and check the DIE inside the chip since it's exposed ). For fun, I am also attaching a photo of a blast of IC (U1) - [URL="https://www.badcaps.net/filedata/fetch?id=3164690"]U1.pdf[/URL] .

I've attached some photos that may help you. Please Check [URL="https://www.badcaps.net/filedata/fetch?id=3164689"]U5.pdf[/URL]...

Now is trying turning ON and OFF every 1 second, and drawing about .3 Amps. That started to happen when I removed CMOS battery(i think it has something to do with auto power ON when removing the CMOS battery). Before it just briefly took 0.3 A on PWR_BTN press and then nothing.. 3 and...

Re: Toshiba C870 Dead

Hi! I have the board from Toshiba to.. It's C870-1EX, MOBO: PLF/PLR/CSF/CSR DSC MB. (As I have researched it's the same platform that's from Toshiba C850).
