Thank you very much for looking Tom. I appreciate it. Shannen Shannen's Electronics 1619 N Taylor Ave. Garden City, KS 67846 (620) 275-4660 (620) 275-4668 (fax) shannen@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx -----Original Message----- From: techassist-bounce@xxxxxxxxxxxxx [mailto:techassist-bounce@xxxxxxxxxxxxx]On Behalf Of Tom Sherman Sent: Wednesday, August 13, 2003 7:46 AM To: techassist@xxxxxxxxxxxxx Subject: [TechAssist] Re: 2nd try - Need part ID for JVC stereo MX-GT80 for D723, and D703 Shannen, I am JVC authorized. I checked and there are no bulletins or tech tips for the problem you described. It sounds like the laser is losing focus or maybe turning off , i.e. no longer lighting. Try monitoring the focus and tracking signals with a scope and also check to make sure the laser B+ is staying at approximately 5VDC.
