Note
- Test the kit before installation! Once the display is mounted it cannot always be safely removed. We ask that you test the kit by hooking it up before removing the screen protector and before fully mounting the display.
- LCD may break if put under too much pressure or dropped. Please exercise extreme caution when installing.
- Damage to console or LCD may occur if you do not trim the cartridge port pins. Exercise caution when trimming pins, wear eye protection to protect from pin debris when cutting the metal. Damage caused by these pins are not covered under our return or exchange policy.
