This is most likely an IC connector problem which a problem with the connector with connects your screen to your board or it is a motherboard problem it can also possibly be with your screen if you have potentially recently exposed it to heat your best option is to get it diagnosed by a local repair shop

Hi,You should ask if you can if the third party still had an google or Samsung account attached to it you should not reset until your sure it will lock it due to an previous account linked to the phone you should contact Samsung support about your problem they will be able to assist you.

Hi,I am not entirely sure but from what I can find the only real mass available disc drive replacement is the 490aaa you could check with Sony support

Hi,From what you have described there are there potential problems.You have damaged the screen while repairing your battery hence the digitizer not being responsive and the lines that disappear and reappear that suggests that the lcd is broken.Second potential problem is the screen and battery are fine the logic board has been damaged and probably needs a micro soldering repair.Third potential problem it could be a battery problem but this is highly unlikely to be reason behind the screen problems but could the charging problem.If a new screen and battery does not fix the problem it is a logic board problem

Hi,The fingerprint sensor is very fragile you may have broken it during your repair.You could replace the fingerprint sensor or take it to a local repair shop for a diagnosis

Hi,I am not entirely sure of what the problem is but from the photos you have uploaded you are most likely indeed correct.It is indeed most Likely a connector problem on the board.Recently,While I was conducting a repair on An IPad Pro I accidentally removed a display flex cable too fast and it damaged the connector and now I am getting it repaired by a micro souldering shop near me.So I would suggest first trying to clean the phone up as from the photos the connectors look a bit dusty do not blow on it or use water You can instead used compressed air or any other approved cleaning method for electronics.If it still does not work you should take it to a local souldering shop to see if they can replace the connector on the logic board.

Hi,From what I can understand from your problem it could come from two potential problems.If you used adhesive strips to close down the device it may be preventing the screen from fitting correctly .It is either that or the flex cable problem you mentioned.I had a similar problem with an Original iPad Air repair where the flex cables would not sit properly under the screen so I had to redo the whole repair not saying you have to to.My best recommendation in this case is remove the screen and when you are putting the screen back on the phone try to when you trying to close it close the screen on the side it won’t fit properly on.If this still does not work to any avail then it most likely your screen.Since your previous broken screen still fits fine your aftermarket screen may not be of a high quality bro I suggest buying a new better quality aftermarket screen from ifixit or Trusted Amazon sellers or Apple original parts that you could find on EBay.

Hi,most likely a factory reset will not fix your problem.From what i can tell if you still have the orginal battery there isa part you can move across from the orginal battery or you can use a programmer to programme the battery to show a certain battery percentage

From what i understand since you ripped one of the flex cables off you may have damaged the connecter on the logic board this is most likely why your experiencing your screen issues.If you are 100% sure there is no problems with your replacement screens it is likely a logic board issue.

Hi,Since you already have cleaned the fan my suggestion would be if you keep the ps4 in a confined space then to move it to an place with more ventilation and if possible to stand the ps4 vertically.The ps4 vertical stand can be found on amazon.
