 DMRE85HP PANASONIC Service Manual by Greg Hatfield;
This is a great site. I placed my order and by the next am it was available for download. Had some problems with some missing copy on some pages. Once I brought the error to the OMC's attention, the issue was resolved. I'll come back again.

Das Service Manual war von der ersten bis zur letzten Seite sehr informativ und hilfreich. Die Darstellung aller Teile war klar und der Text gut lesbar. Vielen Dank, das war nicht der letzte Download bei

Text excerpt from page 29 (click to view)
It should be clear that the base of Q520 should not be more than -1 2vdc and Q518 +1 3vdc Q516 is -1.2vdc +1.3vdc. the bias and its turn on is the potential difference of RC components R540 and R538. Q518 also gets its controlled DC via Q526 A t ll d i Q526. Assuming th t th voltage amplifier i working correctly, th th amount of i that the lt lifi is ki tl then the tf voltage delivered at the base of Q520 and Q518 should be within the tolerance to be g g governed (controlled) by Q516. In general practice two possibilities exist in this case case. 1. The base drive voltage coming from Voltage amplifier stage arriving at Q518 and Q520 is to high to be controlled by Q516 and its associated components. 2. Q516 and its associated switching + RC and Voltage divider R-Nets are failing. Q526, C538, D506, R Nets D504, R562, are all part of the Q516 operators service as reference control to the bias. Is the problem 1 or 2 or both?
