Hi Aaf,
I forget if I have fixed this model, certainly plenty of similar ones.
Q1 - Can you post a photo with the lid removed ?.
Q2 - Does this have a small sub-board mounted to the underside of the mechanism.
Q3 - Can you see the lens bobbing up & down after closing the drawer (no disc).
Q4 - If you give the disc a spin do you hear a quiet swishing sound.

Regards, Eric.

thanks a lot for reply

for Q1 not yet have the digital camera
Q2 yes, the both of 2 IC in the sub board as you mention
Q3 yeah, the lens I think work perfectly
Q4 I don't understand but I just hear the sound of disc
spinning

Maybe I think the trouble cause from sensitive area in this sub but why and what component make the problem

Warm Regards,

Hi Aaf,
A quick lesson in usual cdp operation.
1 - when the drawer closes, the laser pickup will return to the center of the disc.
2 - when the pickup is at center, focus searching starts (lens up/down).
3 - when focus achieved, disc spin is initialised and tracking servo turned on.
4 - if tracking is ok, the pickup will move to the table of contents and read the track/time info and stop.

Q1 - does this have pickup model KSS-240A and white ribbon cable ?.
Q2 - Does the LA6250 look like it has been quite hot ?.

Eric.

Sorry for less information but both of 2 motor not work one to drive the pick-up and the other one to spin the disc make the pick-up won't to center of disc

A1 I'm not really exactly what type of pick up model, yes the pick-up with white ribbon cable
A2 Yes, a medium hot I think

Hi Aaf,
Sounds like you are getting no initialising at all.
You need to check the outputs of all the regulators - look for dry solder joints.
Another failure mode is the LA6250.
If you are good at SM soldering you can change the LA6250 or else the servo board complete (BD board).

Regards, Eric.

ok I think i'm check the regulator but where, in this sub board?
if I change LA6250 is this exactly the problem, but I'll try if I got one, thanks for nice companion and reply, nice talk to you CU

Cheers,
A'af

The regulators are on the main or transformer board.
