Il faut extraire la carte du dissipateur. Chose pas \u00e9vidente car le dissipateur a \u00e9t\u00e9 sertit sur la carte. A l&rsquo;aide de petits morceaux de bois et de petit coups de marteau, la carte glisse lentement du morceau d&rsquo;aluminium, la carte est accessible maintenant.<br>En effet avec toutes ces ann\u00e9es de fonctionnement, la chaleur dissip\u00e9e a d\u00e9coll\u00e9 le cuivre du circuit, et plusieurs pastilles ont craqu\u00e9 (r\u00e9sistances de puissances). Seule solution, il faut gratter le vernis vert des pistes du cuivre au cutter et noyer les pastilles avec de l&rsquo;\u00e9tain frais sur le cuivre restant. Cette op\u00e9ration est un peu d\u00e9licate, il faut m\u00eame refaire quelques pistes avec un morceau de fil, ici de wrapping vu la faible puissance dans ces pistes.<br>Apr\u00e8s v\u00e9rification visuelle et test au bipper, les pastilles et continuit\u00e9s semblent ok.<br>Remise en place de la carte et mise sous tension&#8230;. il ne d\u00e9marre toujours pas&#8230;<br>Le probl\u00e8me

class=\"has-text-align-justify\">Un petit tour avec le multim\u00e8tre en bipper sur les diodes pr\u00e9sentes et une mesure de la valeur des r\u00e9sistances s&rsquo;impose. Diodes semblent ok, un seuil de 0,6v env. pas de court-circuit franc. Afin de pouvoir mesurer correctement la valeur des r\u00e9sistances, il faut dessouder une extr\u00e9mit\u00e9 du composant.<br>Le code couleur qui est encore pr\u00e9sent sur les r\u00e9sistances est coh\u00e9rent avec les valeurs relev\u00e9es au multim\u00e8tre, \u00e0 l&rsquo;exception des 2 r\u00e9sistances de puissances: <br>Mesur\u00e9e : 35k ohm<br>Code couleur: 19,9 ohm (Marron, Blanc, Blanc, Or)<br>C&rsquo;est curieux ce code couleur, je n&rsquo;ai jamais vu une telle dispersion entre le marquage et la mesure, et les bagues ne semblent pas avoir chang\u00e9e de couleur avec la chaleur, et en plus cette valeur n&rsquo;est pas tr\u00e8s normalis\u00e9e.<br>Je laisse de c\u00f4t\u00e9, pour le moment, ce point l\u00e0, car de toute mani\u00e8re je n&rsquo;ai pas d&rsquo;autres r\u00e9sistance en remplacement pour faire un \u00e9ventuel essai, en attendant poursuites des investigations, le soucis est peut-\u00eatre ailleurs&#8230;. enfin esp\u00e9rons.<\/p>\n\n\n\n<p class=\"has-text-align-justify\">Le d\u00e9montage du panneau de contr\u00f4le, est hyper simple, 2 vis et le tour est jou\u00e9. Une petite carte \u00e9lectronique avec afficheur lcd r\u00e9tro \u00e9clair\u00e9, 4 boutons, et dessous le composants de gestion de l&rsquo;afficheur, un M38203E de mitsubishi (microcontroleur 8bits), un quartz, un eeprom LC64A de microchip, un Triac Z3M A009 de ST (1A\/600V pour le r\u00e9tro \u00e9clairage). Et comme il ne semble pas il y avoir de r\u00e9gulateur de tension sur cette carte il faut rechercher les datasheets des composants afin de pouvoir d\u00e9terminer comment le montage prend-t-il son alimentation. Celles du M38203E et de l&rsquo;eeprom, m&rsquo;on permis de trouver le niveau de la tension d&rsquo;alimentation (5v) et surtout sur quelles pins se trouvait cette alimentation. Chose peu surprenante un joli condensateur cms se trouve entre le moins et le plus de l&rsquo;alimentation (pin5 &amp; 6 du connecteur). Un coup de bipper sur ces pinnoches, &#8230; pas de court-circuit&#8230; c&rsquo;est d\u00e9j\u00e0 rassurant. Maintenant il faut remonter le tout et mesurer la tension effectivement pr\u00e9sente: 4v2&#8230; oupps j&rsquo;ai quand m\u00eame l&rsquo;impression que c&rsquo;est un peu faiblard.<\/p>\n\n\n\n<p class=\"has-text-align-justify\">Maintenant, soit c&rsquo;est la carte lcd qui fait \u00e9crouler la tension soit c&rsquo;est la carte gestion \/ Alimentation qui ne donne pas assez (chose probable car j&rsquo;ai d\u00e9j\u00e0 un doute sur les r\u00e9sistances de puissance).<br>Remise sous tension du montage sauf la carte lcd&#8230; toujours 4v2. Donc le probl\u00e8me provient certainement de la carte gestion\/alimentation.<\/p>\n\n\n\n<p class=\"has-text-align-justify\">\u00c9tant donn\u00e9 que la carte Gestion\/Alimentation n&rsquo;est pas bien compliqu\u00e9e, du reverse-engenering s&rsquo;impose afin d&rsquo;\u00e9tablir un morceau de sch\u00e9ma autour des pins 5 &amp; 6, mais \u00e0 vu de nez le pont de diode 1n4148, la zener de 5v1 et le condensateur de 470\u00b5\/16v ne sont certainement pas \u00e9trangers \u00e0 mes 4v2 d&rsquo;alimentations :<\/p>\n\n\n\n<p><em>\u00ab\u00a0SCHEMA perdu \u00e0 retrouver \ud83d\ude09\u00a0\u00bb<\/em><\/p>\n\n\n\n<p class=\"has-text-align-justify\">Voici le brin de sch\u00e9ma de cette carte gestion\/alimentation, j&rsquo;ai pas tout compris ce qu&rsquo;ils ont fait autour du pont de diode avec le Neutre, la Phase et le Fil Pilote, car la connexion de ce pont de diode est un peu \u00e9trange. Les num\u00e9ro entour\u00e9 d&rsquo;un cercle correspondent aux pins du connecteur qui va directement sur la carte lcd.<br>Mis \u00e0 part les r\u00e9sistance R1 et R2 qui ont chauff\u00e9, il n&rsquo;y a pas grand chose qui provoquerait ce soucis de tension.<br>Sachant par exp\u00e9rience qu&rsquo;avec le temps, les condensateurs chimiques ont f\u00e2cheuse tendance \u00e0 s\u00e9cher et quelques fois \u00e0 exploser ou \u00e0 \u00ab\u00a0bomber\u00a0\u00bb, je vais le remplacer par un 470\u00b5F\/25v. La tension n&rsquo;est pas identique, mais \u00e7a n&rsquo;a pas grande importance vu o\u00f9 il est plac\u00e9 il ne fait que du filtrage.<br>Et au passage rebelotte sur la r\u00e9paration des pistes, les pastilles avaient craqu\u00e9 aussi ici.<\/p>\n\n\n\n<p class=\"has-text-align-justify\">Remise sous tension et Oh miracle c&rsquo;est reparti, une belle tension de 5v au lieu des faibles 4v2. On reconnecte la totale et la carte contr\u00f4leur re fonctionne.<\/p>\n\n\n\n<p class=\"has-text-align-justify\">Et voil\u00e0 c&rsquo;est reparti pour quelques ann\u00e9e (j&rsquo;esp\u00e8re). M\u00eame si je n&rsquo;ai toujours pas compris pourquoi il y avait une incoh\u00e9rence entre la valeur mesur\u00e9 et le code couleur des r\u00e9sistances R1 et R2. Si quelqu&rsquo;un \u00e0 une proposition, faites le savoir.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u00ab\u00a0Mon radiateur rayonnant CAMPA Photon est en panne\u00a0\u00bb<\/p>\n","protected":false},"author":1,"featured_media":550,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[9,10],"tags":[],"_links":{"self":[{"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/posts\/548"}],"collection":[{"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/comments?post=548"}],"version-history":[{"count":3,"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/posts\/548\/revisions"}],"predecessor-version":[{"id":569,"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/posts\/548\/revisions\/569"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/media\/550"}],"wp:attachment":[{"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/media?parent=548"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/categories?post=548"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pic18.fr\/index.php\/wp-json\/wp\/v2\/tags?post=548"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
