Thank you for your Answer, but I've tryed nearly all what you have written. I'm going to do that with the Voltage-Meter. If there is any Voltage, I send it to HP<br />

OK, try that. I have had a similar problem with a disk drive - the power connector was not soldered well, and the drive wouldn't work. Easily fixed with soldering iron.<br />
<br />
The voltages you should find are:<br />
black wire - ground (measure other voltages against this one)<br />
red wire - +5V<br />
yellow wire - +12V<br />

I worked in NT4 and the CD-Writer was copy a session of a CD-Rom to my HD, than the nonitor has been black (I don't know why). Now my CD-Writer don't works any more - no power (the carrier don't opens) but the Powerplug is well. When I turn on the Power of my PC, the CD-Writer sounds very bad - I had this problem some time ago with a normal CD-Drive. When I turn off and turn on the Power again (without a long break) the CD-Writer don't sounds. But nothing functions. My Adaptec 2940UW can't find the Drive.<br />
Someone had this Problem too? Otherwise I have to send the Drive to HP<br />
<br />
Please write a comemnt, if you've a good Idea.<br />
<br />
Thank you!
