Can I repair touchscreen without opening the phone?

First I had a full width stripe of about one centimeter height at the top of the screen (just 1 mm below the top edge) where my touchscreen didn’t work ocassionally.

Now, that stripe has moved down about 1.5 cm down. If I hit softly and repeatedly the screen it (sometimes) starts working, and sometimes it freeze completly the touchscreen, and I need to lock and unlock the phone to use it.

If I shake the phone I hear as if something is loose inside of it.

Is there anyway to fix this without opening the phone?

The problem persists even in safe mode.

The pen works fine.
