Dell Inspiron 15z 5523a White Bubbles on touch screen
Hello, the problem is with random generated white bubbles on touch screen.
How can I solve the problem?
I read that the problem is on hardware level.
Now I try to use system with disabled touch screen driver and I wait results.
What your best practice in this condition?

Run the built-in self test -- hold the D key through powerup.
If the fault shows on the screen test, replace the upper half of the system (display panel, touch panel, bezel, frame, hinges and cables are all one assembly).
If the fault DOES NOT show on the self test, it's more likely a faulty GPU - replace the system board.
