\n

Voor wat experimenteer werk aan CDM-0 en CDM-1 loopwerkjes , voor 3 tientjes een defecte Erres speler gekocht..<\/p>\n

CD erin en de cd draait ongecontroleerd snel rond..<\/p>\n

Na het controleren van de voeding spanningen heb ik niet over al de juiste spanning of grounds.
\nEerst maar eens alle draadbrugjes die aan het aardvlak zitten opnieuw gesoldeerd, en dat helpt. De motor draait nu niet meer als een dolle rond<\/p>\n

Volgende check, werkt de lasersturing en werkt de focus….Nee…<\/p>\n

Opzoek naar het probleem kom ik een defect HEF4094 tegen… data ( i2d ) gaat erin inclusief clock( i2c ),
\nMaar geen laser aan signal (L) en ook gaat de focus motor niet op en neer ( FC1 & FC2 ),
\nDus er komt nooit een (FN) focuspunt gevonden signaal dat de spindel motor start<\/p>\n

\"Afbeelding\"<\/p>\n

HEF4094bp vervangen en jawel, Laser-aan (L) signaal is er en de focusmotor werkt. maar geen focuspunt gevonden signaal (FN ) , Omdat ik vermoed dat de orginele laser te zwak , heb ik even een test loopwerkje er aan gehangen en jawel AUDIO<\/p>\n

\"Afbeelding\"..<\/p>\n

Inmiddels alle elcos op servo en decoder print vervangen..<\/p>\n

Binnen kort maar eens kijken of het me lukt wat CDM0 en CDM tot leven te wekken met nieuwe Lasers<\/p>\n

Dit topic<\/a> moet ook maar eens af<\/p>\n<\/div>\n<\/div>\n

mooi die uitleg \u00a0en dit is ook -zie ik- een zeldzaam exemplaar: hier kan het CD doosje ook naar binnen<\/div>\n<\/div>\n

Toch wel veel diverse fouten in een apparaat.<\/div>\n<\/div>\n

Zo een cd speler is ook een hoop complexe techniek.<\/p>\n

Dat was weer een prima uitkeg Bram. Zo langzamerhand vormen jouw bijdragen ook een cursus over CD-spelers.<\/p>\n<\/div>\n<\/div>\n

Bram, wat ik me afvroeg, heb je nog de beuntruc geprobeerd om met R3140 op het preamp\/laser board van de CDM-1 de output van de laser wat op te krikken? Ik heb onlangs bijvoorbeeld op een vergelijkbare wijze weer een CD373 aan het spelen gekregen. Het is uiteraard uitstel van executie en moet voorzichtig worden gedaan, definitieve schade is makkelijk op te lopen. Aan de andere kant, stuk was ie toch eigenlijk al…<\/div>\n<\/div>\n

Even niet technisch, maar vormgeving. Ik heb de Philips CD204 in zo’n kleur, daarin ladefrontje en knoppen zwart zoals in CD304. Deze onderdelen in bijpassende kleur maken was blijkbaar te duur.<\/div>\n<\/div>\n

Ik zie dat mijn vraag in de laserdiode wisseltopic al is beantwoord…<\/div>\n<\/div>\n
