It handles pool connectivity, ASIC clock distribution, fan control, and temperature monitoring. When the original board fails — corrupted NAND, dead Ethernet PHY, or a blown voltage regulator — the miner drops offline entirely. This direct-fit replacement restores full operation without firmware reconfiguration; just swap, boot, and mine.\u003c\/p\u003e\n\u003ch3\u003eCommon Failure Patterns on the C76 Board\u003c\/h3\u003e\n\u003cp\u003eTypical symptoms include the miner not appearing on the network (CPU or Ethernet failure), the dashboard showing zero hash boards detected (data-bus fault), or continuous reboot loops (corrupted boot media). A less obvious failure mode is partial hash-board detection — where only one or two of three boards show up — which can indicate a damaged data connector or signal-level fault on the control board rather than a hash-board problem.\u003c\/p\u003e\n\u003ch3\u003eInstallation and Verification\u003c\/h3\u003e\n\u003cp\u003ePower down the miner and disconnect all cables. Remove the mounting screws, unplug hash-board ribbon cables and fan connectors, and slide the old C76 out. Install the replacement in the same orientation, reconnect everything, and boot. Access the miner's web interface to confirm all three hash boards are detected and hashing. If the firmware version on the new board differs from the one on your network, update it to the latest Bitmain release for feature consistency across the fleet.\u003c\/p\u003e\n\u003ch4\u003eA113D C76 Control Board – Compatibility\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCPU\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAmlogic A113D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eBoard Version\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eC76\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eSubstrate\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatible Models\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eS19J, S19J Pro, S19J Pro+, S19XP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCooling Type\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAir-cooled SHA-256 miners\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated Antminer S19J Control Boards \u0026amp; Repair Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/antminer-s19j-s19jpro-bitmain-control-board-beaglebone-motherboard-replacement\"\u003eS19J \/ S19J Pro Beaglebone Control Board\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/bitmain-antminer-s21-control-board-amlogic-c76-a113d-repair-replacement\"\u003eS21 A113D C76 Control Board\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/low-power-yt8512c-ethernet-phy-chip-antminer-s19jpro-c76-control-board-repair\"\u003eYT8512C Ethernet PHY – S19J Pro C76 Repair\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sy6280aaac-qwahe-ultra-low-rdson-switch-antminer-c76-a113d-control-board-repair\"\u003eSY6280 Switch IC – C76 A113D Control Board\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNeed S19J control boards in quantity? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e for availability and volume pricing.\u003c\/p\u003e\n\u003cp\u003eWorldwide shipping from our Shenzhen warehouse.\u003c\/p\u003e","brand":"LYS Shenzhen","offers":[{"title":"Default Title","offer_id":42887540146355,"sku":null,"price":29.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/Bitmain-Antminer-S19j-S19jpro-Amlogic-A113D-Motherboard-version-C76.webp?v=1747888098","url":"https:\/\/lys-sz.com\/products\/bitmain-antminer-s19j-s19jpro-amlogic-a113d-motherboard-c76","provider":"LYS Shenzhen","version":"1.0","type":"link"}
