Motherboard availability and replacement?

hello,

My Samsung S4 is throwing a SIM card not found error with some frequency, but not always. I already changed the SIM part without luck. So, I believe the problema is on the mainboard.

Im looking for a motherboard for my Samsung model on this site, but cant find one. Is it normal? Where can I buy one? Also, soemone in a repair store said to me that is not possible to replace the motherboard of this kind of Samsung... does it make any sense?

thank you!

Answer this question I have this problem too

Is this a good question?

Hello Kevin ,

as i believe the motherboard replacement is the final option to get. why don't you try to troubleshoot existing motherboard?

Sim reader replacement doesn't make sense if there are no damages on contacts (interface)

  • Check the PM output : you should required to oscilloscope to analyze

So many professionals around there so they willing to help. you are not alone buddy, try to fix it by your self :-)
