SM-910f - GSM-Forum

Hi,

Have here a SM-910f which is "dead". Can't start, no Samsung Logo. The only thing which works if I plug it in to a USB charger. Then it gets the Battery logo and the charging led.
My assumption is that U7002 is dead (No voltage on C7128, No signal on OSC7000).
But there starts the Problem. Where can I buy this U7002? I've found in the Internet that it should be a Samsung Shannon 60X6R8. But I can't find this on Aliexpress or something else. Someone any idea where I can buy this?

Thanks

Berkutta

After a slight reflow over the power supply section it tries to boot. It comes to the samsung logo, sometimes even to the carrier logo. I think a cap is bad or something like that. Anyone have expirience which caps are failing in the SM-910F? Or does anyone have a list which cap has which value?
