If cleaning is a must, then video screens need to be treated with EXTREME care.
The following rules must be adhered to when cleaning video screens (whether they are TV sets at home, computer monitors, or in the car)
1. Never use harsh chemicals like ammonia (Windex). Avoid anything with abrasive compounds (i.e. anything with the word "polish"), even if it says safe on plastic or soft surfaces.
2. Never use ANY type of paper product. (paper towels, kleenex, toilet paper) Paper is made from wood pulp which is abrasive by pure definition, no matter how soft and fluffy it might look. Think of it like wiping with sawdust.
3. Avoid "microfiber" cloths that claim to be safe on screens. Microfibers collect dust and dirt particles and trap them in the cloth. These particles themselves are abrasive and then get dragged across the surface as you wipe.
I prefer to use synthetic, lint-free cloths like they have at the eyeglass stores. I own a lot of pairs of Oakley sunglasses which are incredibly easy to scratch. But even after years of playing golf and skiing, I almost never scratch mine because I am careful with them and only use the soft, lint-free cloths they recommend.
4. Do not use pressure when wiping. If a spot is stubborn and won't come out, just be patient and see if gentle wiping eventually works. If not, then give up. A spot is better than a scratch from applying too much pressure.

The black cable can be pulled out and removed. The ribbon requires removing a metal plate with a phillips head screw, then flipping the plastic retainer upward (perpendicular to the circuit board.)

Installation is the reverse of removal. Once installed, the replacement display part is exactly the same as the OEM screen.
The only issue is the "VOID" sticker will have to be violated to do this.
