my phone doesn’t work even you connect it to the charger doesn’t show any thing on the screen. the battery is good and screen is good but i don’t know what’s is the problem .
As @oldturkey03 says, the first things to try are a known-good battery and charge port. Replacement parts, especially small parts, are notoriously hit and miss. If you say a repair shop already tried these things (at least a battery and screen), then you may have a defective charge circuit. Did the phone just stop “working” (i.e. charging) all of a sudden or did this coincide with a fall or impact or water infiltration? A charge circuit repair requires micro-soldering and is not a DIY repair. Look for a shop that does micro-soldering and they will properly diagnose your phone (it may not be the charge circuit). Costs will vary depending on your location.
