Salut à tous,

Merci

Re: potentiomètre Duo
Je sais pas
en parcourant un peux tous les messages sur le forum, tous le monde parle de modifier la vitesse de rotation du lecteur via le potentiomètre. En regardant j'en vois qu'un ( du moins si ça en est un ) sur le bloc optique à coté de la broche rouge.
Edit : il me semble avoir trouvé !!!il sont vraiment petit à coté il y a marqué VR 104 etc ....

Re: potentiomètre Duo
oui mais il faut faire attention avant d'y toucher, un recap d'abord est plus judicieux.

Re: potentiomètre Duo
Merci pour l'info, mais je pense que c'est trop tard
je comprend mon lecteur tourne bien mais il reste sur la gauche du rail, comprend pas je me tâte à acheter un nouveau bloc, mais maintenant que j'ai touché au potard je ne sais plus quoi faire.

Re: potentiomètre Duo
alors il est peut-être bloqué, tu peux essayer de le faire glisser hors tension pour voir.
sinon...
VR102 and VR104
VR102 has a small range of adjustment in which the CD will start to spin. If you turn it and the cd starts to spin, then you know you have found one end of the adjustment. Keep turning it until the CD stops again. Once you know approximately where those two points are, you can find a sweet spot in the middle.
VR104 seems to be similar to VR102 in that there is a certain range in which the CD will spin. Again try and find the sweet spot in the middle of the two points of spin/no spin.
By this point, hopefully you have the CD spinning, and maybe even attempting to read! So lets move on to the next pot/s.....
VR101 and VR103
VR101 is kind of a by ear pot. There seems to be a small range that works for proper cd playback. Typically it seems to be in the 0 to 45 degree range with 0 degrees being horizontal. You should hear some scratchy funny noises when VR101 isn't adjusted properly. Try and find a quiet spot for it. If you go too far it will get very noisy. Hopefully you can find a spot where the CD audio will start to play.
VR103 is, from what I can tell, an error correction adjustment. Hopefully you have got a CD spinning reliably at this point. You might hear a whiney faint scratchy noise at this point.... adjust VR103 clockwise until the noise goes away. If you go too far, the noise will come back only it will be a lower tone and not sound good.
Try and find the sweet spot where the laser operates quietly.
VR105
Lastly, VR105.... This is an adjustment for the spindle speed correction. I'm not 100% on the best way to describe adjusting this one. Basically if the spindle speed starts to run away (go REALLY fast) then you've gone too far. Hopefully by this point, your CD will play music. Try and play later tracks on the CD and if they struggle to play, try adjusting VR105 until you can play all the tracks reliably.

Re: potentiomètre Duo
Franchement fait déjà un recap avant de trifouiller le lecteur. là c'est comme si tu démontais le moteur de ta voiture alors que c'est peut-être juste les bougies à changer.
La Pc Engine c'est bon! mangez en!

Re: potentiomètre Duo
S'il est fixe au centre du CD au début ça me semble normal.
Il faut régler avec un CD audio au début.
