Dear Sir,
Document is original service document of sharp. I had a problem with the door contacts. Fuses where blown. With the manual in a few minuts is was clear what the problem was.
Manual was of great help.
With kind regards,

The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

let's say first that i do not need to have a credit for my opinion, i am a retired sparkie and i voluteerd to fix an electronic device for a local "Youthgroup",as no diagram was present i checked the "net" and gambled on this site and paying some fee via PayPall, i was gladly surprised that the manual arrived as was stated, GOOD SHOW, and best wishes, John
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?
