Changing a Laser

[laatsch55]

No, the Elenco goes to 30.

I found a digital one that goes to 60. 30 is good; because the highest most circuits are is 24vdc. That is the highest.

That youtube was for a Panasonic laser marker. Misspost? Or if that's what you worked on, very cool!

 

[avionic]

It was a Sunx CO2 laser marker I replaced .. I don't do CD and DVD laser work.

 

[stuwee]

You work on some very interesting gear Dave

 

[avionic]

You should see the Boilers and airhandlers..LOL

Very late to this thread Larry.
First, do you see any red light when you close the tray with no disc? Is the lens moving up and down? Did you open the shorting pins on the KSS-213 laser?
BTW, do not change the chip. Cancel the order if possible....it will not solve your problem!

No to all questions. Why what is up? Where are the shorting pins? What is wrong with it?

Look at the laser's pcb, solder side. In the lower left corner you will see a small solder blob. remove this solder, and the pickup will work.

 

[speakerman1]

Why would the spindle motor not work. No voltage at any time?

Larry

 

[nakdoc]

The spindle won't turn until FOK (focus OK) goes low. The laser has to emit light so the focus error can be determined.

Thanks I'm getting good at taking it apart. Will look tomorrow.

SLACKERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[speakerman1]

Yea like Fedex hasn't called me 10 times so far. LOL

Larry

 

[laatsch55]

Got it worked out?

 

[speakerman1]

Yea so far so good. Already had a brokerage acct with them. It should have left Canada by now. LOL

Doc I see one small blob by itself on the L/H side of the PCB is that it?

Larry

 

[laatsch55]

I believe thats what he meant. You can always put it back.

That's the one. When you touch it with your iron the solder will go away.

 

[speakerman1]

Will do that project later. LOL Listening to some good jams at the moment about to put the Frank Marino in.

Larry
Thanks Doc
