One repair is a screen swap; the other is a cable fix. Both start with the same question: which replacement part belongs on your workbench? When you're shopping for gaming replacement parts modding, the answer depends on the console you're repairing and the component that failed. A DS Lite with a cracked upper display needs the Top Upper LCD Screen Display Replacement Part for Nintendo DS Lite NDSL Console. A Switch Joy-Con with unresponsive buttons needs the Lots Button Key Flex Cable Replacement Parts for Nintendo Switch Joy-Con Console.

Product Notes
Top Upper LCD Screen Display Replacement Part for Nintendo DS Lite NDSL Console

If your DS Lite's top display is cracked, faulty, or broken, this replacement screen is a direct match. The description says a backlight kit is pre-installed, which removes one extra step during the repair. It is listed as a display LCD with Nintendo DS compatibility, so it is aimed at a DS Lite upper-screen job rather than a general modding accessory. The trade-off is that this part is specifically a top screen for the DS Lite, not a display meant for other consoles. If your repair is the upper screen, the pre-installed backlight and the direct fit make this the part to plan around.
Lots Button Key Flex Cable Replacement Parts For Nintendo Switch Joy-Con Console

If a Joy-Con button is not registering because of a worn cable, this set is a practical way to get spare button cables on hand. The title says these are button key flex cable replacement parts for the Nintendo Switch Joy-Con, and the attributes list the compatible product as a controller. It is also shown in Multicolor, which fits a controller repair where you are matching multiple button positions. The limitation is that the part is specifically the button cable, not a shell, joystick, or full Joy-Con replacement. If the problem is the button flex path rather than the housing, that narrow focus is exactly what makes it useful.
Final Choice by Use Case
Pick the Top Upper LCD Screen Display Replacement Part for Nintendo DS Lite NDSL Console when your repair involves a cracked or faulty upper screen. Pick the Lots Button Key Flex Cable Replacement Parts for Nintendo Switch Joy-Con Console when you are repairing Joy-Con buttons and need a spare button cable.
