    Nichts ist mehr wert, als wenn man etwas selbst repariert und dabei lernt was dazu. Gutes Video.

      Das können Sie aber nicht von ein paar Reparaturen und auch nicht vom zuschauen. Dazu sollten Sie einen Technischen Hintergrund haben und sich viele Jahre (in meinem Fall sind es 40 Jahre) damit beschäftigen. Das ist nicht so eine "Ich repariere mal schnell was" Geschichte. Aber ich hoffe das Ihnen das klar ist. LG

    Thanks for video.
    I have this cd player.
    My problem is that the player is not playing at the start but will come gradually to play in 10 to 15 minutes when warming up.
    Is the problem for me only the 3 capasitors?
    I would have loved to se a picture of where you grounded the two transistors. It was not shown well in the video. Keep up the good work 🙂

      I don't remember it but I think the Electrolytic caps and the Voltages from the Regulators (7815, 7915, 7805 and so on) are often defect.

      @@weakbit633 I will maybe try to put 3 new Electrolyt caps in it. I don't have the skill you have, analysing and follow a diagram. Am I lucky the player might work.

      @@johnpedersen8387 This is clear I worked professional for over 35years in this Industry - but you can change the Electrolytic caps as well. Only watch on the correct polarity (stripe is minus on the Electrolytic caps) if not then the Elko explode! Also watch for solder joints they can also be broken and interrupt - so solder them too. Good luck!

      @@weakbit633 I tested the cd here this morning. My thoughts was dried out componets. So I warmed a 10 mm bolt up with my heatgun several times and put it on top the electrolytic caps, and let them take the heat down. Then I put on the power and tested if sound was present. The sound was present, but not in the correct volume. Then I took the heatgun and swirped heat over the caps and the components with heatsink on. And in just a couple of seconds the cd player played clean sound in the right volume. I can not know if other small components on the board can be affected. The lid of the player was marked with black dust, in the place where electrolytic caps was and the parts that have heatsink on. When I put my hand on the heat sinks they were wery warm. Is the componets there this warm normally, or is the component defect do you think?

      Michael so spricht man nicht! Das heißt "Not Another Day" oder wie haben die geheißen. Die Kunden die ich mal hatte waren begeistert vom Klang also mit Rauschen war da nicht so viel aber das Print Material das verwendet wurde war nicht sehr gut. Beim Transport sind so manche Leiterbahnen einfach mal von der Print herunter gehüpft. Wenn sie aber spielen sind die gut. Zumindest wenn. Was für CD-Player verwendest du?
