Introdução

This is a guide for replacing the motherboard of the CAT S48c. You can find a replacement part on Ebay: OEM SPRINT CATERPILLAR CAT S48C 16GB LOGIC BOARD MOTHERBOARD.

Water may leak into your CAT S48c and fully damage your motherboard without you knowing. If the CAT S48c isn't powering on or experiencing hardware issues like not charging, screen flicker, or not powering on, this guide will show you step through step on how to replace it.

Common symptoms are:

  • Frequent reboots
  • Not turning on
