Screen flickering and touch pad not working

My screen started flickering and the touch pad is not working(but working with a mouse) when it does that. The weirdest part is it works well one day and if I restart next day it will flicker continuously and never stops.

I tried the following things.

1. Resetting NVRAM and SMC but No luck.

2. Run it in safe mode but it still doesn’t solve the problem.

3. Ran the diagnostic and it says everything is good :(

4. Cleaned almost all of the software except chrome and adobe.

I am not sure what steps should I take next ? Is it coz of overheating or may be the some sort of loose connection between the board and screen ?

the camera is also not working when the screen is flickering

You'll need to see if the problem is present using an external monitor using a Mini DisplayPort or Thunderbolt dongle to what ever your display uses.

Hey Dan! Thanks for responding. I tried connecting it to external monitors and everything is working fine in those monitors. It’s just my Mac screen is having the same problem.

Sounds like you’ve nailed it as something within the internal display! MacBook Pro 13" Retina Display Early 2015 Display Assembly Replacement see if the logic board has corrosion around the Display cable in Step 11.

Hey Dan! Thanks for the link.

I cleaned the area around display cable. It worked well for a while but then start doing the same thing in couple of hours. Although I found the flickering get worse if I move the display cable. It seems like the end of display cable has become old . I am not sure if that’s the case ? Is there a way to test that?? I am adding the image in the question.

Sorry can't see anything in your picture as the connections are all covered up! Take a picture thats like the one I just posted in my answer so we can clearly see the contacts of the cable and the solder joints on the logic board.
