hey.. I have a V7 here that i thought had a bad laser. replaced the laser and now only CDs will boot. I noticed that pin 7 on the BA near the laser is only 55ohms away from GND. Could it be blown and still read CDs? I tried w/ and w/o the Matrix chip in it. And tried adjusting the laser and the POTs (DVD is currently at 1000, factory was at 1560).
