After replacing the charging port, still wont charge

I noticed the charging port was not charging well, only when you forced the port in some directions. I changed the charging port on the tablet and it wasnt charging. I tried replacing the flex cable, same problem. I even tried another battery and it still gets 0A and doesnt show it is charging. I already tried another charging port and I have the same problem. I testes the mainboard and it seems to be getting 5V. Any help?

@servicebarreiro what voltage do you get on the battery connector? Have you tried a USB ammeter to see what your tablet pulls?

@oldturkey03 could be a bad replacement port to be fair, you know what chinese copy ports are like

@oldturkey03 It pulls 5V but 0A. I tested the mainboard and it is getting 5V but I don't know where exactly to check the battery connector for voltage.

@tech_ni That's the thing, I put back the old part (since it was getting some charge when pressed just right) and it still didn't work. I ordered a new part (servicepack) and let's see if it works.

Hi @servicebarreiro

Here's the troubleshooting section from the sm-t505 (LTE version of your tablet) service manual, that may help, as I think that as far as the charging circuit is concerned that it would be the same as your model variant.

Go to Sect. 8-4-2. Charging on p.12 (of 29 pdf numbering) of the manual and follow the flowchart and check how far you get when following the paths.

On p.13 there are images showing the location of the components mentioned in the flowchart.

Unfortunately there's no parts list in the service manual so if a component is faulty it may be hard to find the correct replacement part.
