Even when the screen display is turned off, the screen will still crash and crash. The condition of the phone that heats up often occurs at the bottom of the screen because in that section there are flexible components that contain capacitors and IC items.

If you are using an IC item from an unused device, use a soldering iron to remove it. Replace the IC Item on the LCD to be repaired. Next is to pre-precise the IC item on the flexible part that has been given a special glue.

Wait a few moments for the component to automatically attach to the flexible part. Give flux on the IC part contained in the flex and stick the flexible part on top of the solder to make it stick faster. Double-check whether the component has stuck to the flexible, using thinner rubbed on it.
