Post subject: CLD-R7G Repair Posted: 02 Jul 2017, 07:00 |
|
So it seems i'm going to have to repair the CLD-R7G I had shipped by j-subculture. I requested the extra secure packing, and they didn't do it. It arrived single boxed with a little bit of styrofoam peanuts and single layer of thin bubble wrap.
The case has a nice dent.
The first disc I put in the player made a horrible squeal, and then the player gouged the crap out of it. I took the cover off and looked at what it's doing. Apparently it tries to spin up LDs while the head is physically making contact with the disc. I get nice F5, E4, E0 errors randomly.
Not sure where to start.

The good thing is there are lots of players based on this mech so you can pretty much look at any other players inside and see what is wrong. Should be something easy, unless its something hard Good luck with it and keep us posted.

it's moving the head into contact with the disc. i don't quite understand how the head is constructed but it looks like there's some kind of proximity sensor on the head assembly. after it loads the disc, it moves the head assembly up until it mashes into the disc. then tries to start spinning the disc. needless to say this is not good. i'm guessing the proximity sensor may be damaged?
all rails look undamaged. no broken plastic is found anywhere. nothing seems loose.

not sure what risk you mean, the player is broken. what less risky option do you recommend as an alternative to doing nothing?

according to the service manual for the cld99 it's a pickup assembly.

it appears the player is crashing the tilt sensor right into the disc. you can see melted plastic from the spinning disc deposited on it.

Risk = risk, if you try to fix it and don't know what you are doing you are taking a risk, aren't you If you do know what you're doing you aren't taking a risk, right Anyway that part should not be scraping or hitting anything. Good luck with it and please keep us posted, I remember when I received my R7G years ago rods and other parts were loose inside. It was packed well, just a travel from overseas and handlers will do it every time. Yours was also packed poorly but mine was not.

so the tilt sensor is basically trashed. i need another pickup assembly.
anyone know what other models share the same pickup assembly as the cld-r7g?

picked up a donor CLD-D604. we'll see how the transplants go.
I think i'll also transfer the power supply so I can ditch the 100v stepdown converter.
