Servicing CD/DVD players

[Asjad]

Dear All,

I have repaired TV/Videos in the passed but I have never understood
how you can repair a CD/DVD player.

Normally you have system ON to test for volatges/waveforms
but wont the laser burn your eyes, do you use a test CD to get
reference waveforms

What is the general rule of thumb to protect your eyes from being blasted
while you test the device??

Your opinion is always valued!

Anything can be repaired the question is it worth the time and effort.
The cost of a basic CD or DVD has reached the $50US mark. If you have a shop rate of $30US@Hr and have to buy a sub assembly for $40 plus shipping, you have cost more then a replacement.

Poking around either device , to learn is another thing. You dont have to worry about burning your eyes , just don't stare directly into the laser. It uses a visable spectrum so it's not like you can be inadvertantly harmed and there are warnings even inside the things as to HV and Laser light.

Play and have fun.
