Well, he has pads that need to be pressed on board, you have pins that need to be soldered on board, i would open it and wiggle left right top bottom press in, see if you have a bad solder connection on some pin (you should see solder “unglue-ing” from board or something) , i dont know how will tape help, i assume youll just have trouble putting mask on since your screen is not removable… Bad solder connection requires desoldering and soldering again…
