Changing a Laser

[Skywavebe]

Wow, I am amazed that you would attempt this without a clear idea of what was wrong with the unit.
Laser replacement is not that hard mechanically but you need to have all your ducks in a row.

It is no biggie. I was given the wrong info. So I'll have a new laser and motor and if that isn't it I have something else new. I have no manual for this unit and all I have is it is a Sony transport. So I'll go from there the best of my ability.

Well after 2 weeks of being on back order. The motor gets here today, Don't know if I will get to it or not. Loader is kicking my butt again.

Well I woke up this AM. The spindle motor got here yesterday. So I have installed it. Pray this works. Here are some pics. I am about to test it in a bit.

Wish me luck

You would think one day I would learn to take pics while I take stuff apart. LOL

Ok no voltage to motor. Will pull the board. Have schematics. Who would like to troubleshoot the board for me. I'm not that good to solder the chips. Try to find whole board. No go. Have continuity thru the motor. I do want to get this going. I'll even pay. LOL

PM me with your price.

Send it on with the schematic. Time i learned, this aint gonna be our last correct??

No but Jerry is going to do a road trip next weekend. If the control chip went it is 45.00. Could find a Sony with the same transport for that much; but how long will it last. LOL

Well it wasn't the laser. LOL Now we will change the spindle motor. I have some pics.

You got a spare good laser? What is the assembly number?

 

[speakerman1]

I have 2 KSS-213B and a KSS-240A.

Well I found a control chip. I should have tried the whole board. It will probably take a month to get here.

Larry

 

[laatsch55]

From where???

 

[speakerman1]

I'll furnish a link in the other post.

I did get a 124 pin chip puller.

Larry

 

[laatsch55]

need a pic of that.

 

[speakerman1]

They already sent it. When it gets here I'll take one.

My AA cdp got here. The tray will come out but not go back in. When you push it in manually it comes back out after 20 seconds.

 

[speakerman1]

Did you push it in with a disc?

Larry

 

[laatsch55]

Yes.

 

[speakerman1]

Well I guess I should go check the mail for the puller. They sent the chip from Singapore. So it is coming. I have to learn how to trouble shoot boards again. Instead of doing what I think it may be. I did get the new meter. I also am watching a new power supply. How high does your go Lee? Wasn't it 36vdc?
