Good,readable manual. I found other manuals that were not readable when it came to part ID, but the one downloaded from owner-manual.com was better than expected. I will do buisness with owner-manual.com again.

Service Manual that I received was very helpful to me. Thank you.

The manual is well organized and is easy to read. The chapters are following normal way to proceed.

This scanned manual is well done in that most all the pages except for one is straight and clear- the way I would do them. One page was upside down but that happens. For the money that is charged on this site you get a pretty good deal. Now with complex repairs, I still prefer to us paper manuals which I have to buy at stereomanuals but the one I got here was much less than the $45 he was charging but this is a larger than normal manual for three different units. I am a picky manual user because I have used original manuals from Sony and Teac.

Very useful service manual, was exactly what i needed.Good quality,reasonable price.Thank you.
Service manual CP 385 / CP785
¬ When the MOSFET is ON, the STR-F6653 internal capacitor C1 is charged at the constant voltage 6.5V. At the same time, the voltage at pin 1 (OCP / FB) increases with the same waveform as the MOSFET drain current. - When the pin 1 voltage reaches the threshold voltage VTH1 = 0.73V, the STR-F6653 internal comparator 1 starts operating. The STR-F6653 internal oscillator is inverted and the MOSFET turns OFF. ® When the MOSFET turns OFF, charging of STR-F6653 internal capacitor C1 is released and C1 starts discharging by the STR-F6653 internal resistance R1. So, C1 voltage starts falling in accordance with the gradient regulated by the constant discharging time of C1 and R1. So, this means that the fixed time determined by C1 and R1 is the OFF-time of the MOSFET. ¯ When C1 voltage falls to around 3.7V, the STR-F6653 internal oscillator is reversed again and the MOSFET turns ON. C1 is quickly charged to around 6.5V The MOSFET continues to oscillate by repeating the above procedure. * STR-F6653 protection circuits � overcurrent protection function (OCP) Overcurrent protection is performed pulse by pulse detecting at STR-F6653 pin 1 (OCP) the peak of the MOSFET drain current in every pulse. � latch circuit This circuit sustains an output low from the STR-F6653 internal oscillator and stops operation of the power supply when overvoltage protection (OVP) and thermal shutdown (TSD) circuit are under operation � thermal shutdown circuit (TSD) This circuit triggers the latch circuit when the frame temperature of STR-F6653 IC exceeds 140°C � overvoltage protection circuit (OVP) This circuit triggers the latch circuit when the Vin voltage exceeds 22V (typ.)
