Hi Guys, I have a friend’s 6s Plus that has had a screen replacement and is now not responding to touch. The iPhone was initially repaired at a local phone shop, although it only cost my friend £60 and therefore I assume that it was either a cheaper aftermarket screen or it was not a full replacement. However, after a while, it either stopped responding to touch and was then cracked again or the other way around (my friend is unsure). The phone shop will not repair it for free and are saying that it will cost about £100? Hence why I have the phone. Furthermore, somebody else has taken this phone apart since it stopped working and then it worked for a few days… Is it just a case of replacing with an OEM part or is this a board issue? I have read that it may just be a flex cable or the damage to the screen has caused it to not respond to touch but I am worried that it may be the connectors on the board being damaged…

@douglasvinicio is mostly correct … Change the LCD. The IC responsible for touch is on the LCD Flex and not the logic board like the Iphone 6 and 6 plus. If the screen got cracked, then most likely even a bad digitizer. I also do not warranty my LCD’s after a break or water damage. I warranty my LCD’s for a lifetime provided they are not broken or obvious water damage. It is possible that the FPC Connectors are damaged, but from what you described, a new LCD will fix this issue and is needed next to continue your troubleshooting

Before taking any conclusions you must disassembly the screen and take a look what it looks like on the inside. 1 - Check if the flex cable is still conected. 2- If it is conected try a new screen or a old one that you are sure that is working. 3- If doens’t work check for dammaged conector or components (capacitors,diode,etc) around the touch screen conector. 4-If everthings ok maybe you’re facing a Touch iC issue. Then you need someone with the skills and the tools to do the job. Answering your question about OEM parts,i can only tell you about my experience. I neved had any problems working with not original iPhone parts,I installed many iPhone 6s screens not original ones most part and never had this kind of problem caused by a bad part so i thinks is unlekely. And if the repair shop charged you 100$ without aven disassemble the phone and had done a complete diagnosis i would say find yourself another professional to take care of your phone.
