Screen cracked but still working. What do I need to replace?
I just dropped my old Samsung Galaxy Tab E9.6 and the screen is badly cracked with bits of loose glass, but the LCD still works.
When I search for replacement screens, I mostly find stuff that costs $50 or more that include a new LCD, but I also find a few results that only replace the digitizer but not the LCD, for $11-20. I’m not entirely sure what a digitizer is, though.
Is that good enough for my situation? LCD and touch still work fine as far as I can tell, it’s just the glass that’s badly cracked.
(Also, the home button doesn’t work anymore; I suspect water damage from way back. I can work around it, but if this replacement also fixes the home button, that would be a nice bonus.)

As regards to the Home button the impurities in the water causes corrosion and this could’ve damaged it or the circuit components associated with it.
When disassembling the tablet to replace the touchscreen check the systemboard for any signs of corrosion. If there are then you need to clean any affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better
As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.
You could try replacing the home button board and see if that works. Perhaps only the button contacts themselves have been affected.
Here’s a link to a supplier of the part (example only). It is only to show the part and what it may cost. There are other suppliers online that may suit you better. Just search for Galaxy Tab E 9.6 (insert tablet model number) home button board to get results.
Golden rule when repairing battery powered electronics. Unless you are testing, always disconnect the battery as soon as it is accessible before continuing with the repair and reconnect it as late as possible when reassembling to avoid any electrical problems from occurring.

Thanks! The home button is less of an issue to me because I only really use this tablet for a single purpose. I'll keep an eye on the state of the home button when I take it apart, and see if I can fix it. The important part is replacing the glass, for which the digitizer part is clearly the thing I need.
