Nie stosuje si\u0119 w nim przede wszystkim inwertera. Oczywi\u015bcie co\u015b musi sterowa\u0107 pod\u015bwietleniem naszej matrycy. Na elektronice matrycy znajduje si\u0119 sterownik, kt\u00f3ry odpowiada za napi\u0119cia oraz sterowanie ledami. W przypadku braku pod\u015bwietlenia nale\u017cy sprawdzi\u0107 matryc\u0119, lecz bardzo rzadko zdarza si\u0119, aby tego typu pod\u015bwietlenie uleg\u0142o uszkodzeniu. Nast\u0119pnie sprawdzamy ta\u015bm\u0119 matrycy czy nie jest p\u0119kni\u0119ta i czy odpowiednie sygna\u0142y oraz napi\u0119cia generuje p\u0142yta g\u0142\u00f3wna.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":10,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"on","neve_meta_content_width":100,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"on","footnotes":""},"class_list":["post-206","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/ram-service.pl\/index.php?rest_route=\/wp\/v2\/pages\/206","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ram-service.pl\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/ram-service.pl\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/ram-service.pl\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ram-service.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=206"}],"version-history":[{"count":3,"href":"https:\/\/ram-service.pl\/index.php?rest_route=\/wp\/v2\/pages\/206\/revisions"}],"predecessor-version":[{"id":214,"href":"https:\/\/ram-service.pl\/index.php?rest_route=\/wp\/v2\/pages\/206\/revisions\/214"}],"up":[{"embeddable":true,"href":"https:\/\/ram-service.pl\/index.php?rest_route=\/wp\/v2\/pages\/10"}],"wp:attachment":[{"href":"https:\/\/ram-service.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=206"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
