Een Marantz CD85 die na elke uren diverse CD’s niet meer wil in lezen, de speler is al eens onderhanden genomen<\/p>\n

\"\"<\/p>\n

Diverse elco’s zijn vervangen maar niet alles , doorgemetaliseerde printen moet je met beleid desolderen<\/p>\n

\"\"<\/p>\n

Desolderen van elco’s, er is flink op los gebakken..:-(<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Een nutteloos draadje<\/p>\n

\"\"<\/p>\n

Wat ik dan wel weer bijzonder vind is dat de voeding niet is gerecapped. diverse 47uF’s nog maar 5 tot 10uF<\/p>\n

\"\"<\/p>\n

Bij het opnieuw solderen van connectors is dan wel weer een punt vergeten , schuurtje in tin.<\/p>\n

\"\"<\/p>\n

Print schoongemaakt van flux en nicotine en voorzien van nieuwe elco’s<\/p>\n

\"\"<\/p>\n

Terug bouwen voeding<\/p>\n

\"\"<\/p>\n

Zijn alle voedingspanningen aanwezig , check<\/p>\n

\"\"<\/p>\n

Op diverse plekken eilandjes verdwenen<\/p>\n

\"\"<\/p>\n

Mainboard voorzien van nieuwe c’tjes<\/p>\n

\"\"<\/p>\n

Alle enkelzijdige printen opnieuw gesoldeerd.<\/p>\n

\"\"<\/p>\n

Lampjes vervangen door led’s , afregelen en testen maar<\/p>\n

\"\"<\/p>\n

Na uren spelen toch nog problemen, na wat zoeken meten en kijken met scoop zag ik ineens het oogpatroon verdwijnen , deze connector lijkt het probleem wiebelen en friemelen , en het werk weer en weer niet, kontaktjes vuilen, schoongemaakt met glasstift en testen maar weer<\/p>\n

\"\"<\/p>\n

Stekker voedt CMD-1 Mk2 print<\/p>\n

\"\"<\/p>\n

Ziet er stabiel en schoon uit…<\/p>\n

\"\"<\/p>\n

Backupje gemaakt<\/p>\n

\"\"<\/p>\n

Er blijken toch weer problemen te zijn met de Speler, na uren speler soms in eens stoppen, Testen in service mode<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Laser wisselen,<\/p>\n

\"\"<\/p>\n

Laser in CDM-1 Mk2<\/p>\n

\"\"<\/p>\n

Loader met CDM-1 Mk2 weer samen bouwen<\/p>\n

\"\"<\/p>\n

Waren deze deukjes de oorzaak ?<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Of onder deze plastic ring, de Flexpoint is hier gevouwen<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Was dit de oorzaak..?<\/p>\n

\"\"<\/p>\n

Verder rondneuzen<\/p>\n

\"\"<\/p>\n

Laserdiode vast gelijmd in chassis<\/p>\n

\"\"<\/p>\n

Closeup photodiode opnemer<\/p>\n

\"\"<\/p>\n

Marantz CD 85 – “Conclusie: De speler is perfect in orde. Nogmaals bedankt en tot een volgende keer.”\u00a0<\/strong><\/p>\n
