The service manual was a copy of the original from Wirlpool. The quality was good, all neccecary information was available including the service-codenumbers, so I could order the right part to be replaced for repair.
Downloding was no probem after the payment.
Thanks for the service!

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.

Recovery flowchart (1-1)...Changing the Vol Offset setting voltage
Note: Disregard the discharge that may appear during voltage-change setting.
[From the main flowchart (1)]
Display RST MASK 09 (light blue). / [MKS S59]
� If RST MASK 09 (light blue) is already displayed, skip this step.
B
Set VOL OFFSET to the setting value 000. / [VOF 000] � This setting becomes VOL OFFSET_min1.
Gradually increase the VOL OFFSET value until disappear the discharge (lit cell). The VOL OFFSET value must be 245 or less.
VOL OFFSET_min1
Note: Make a note of this VOL OFFSET_min1 value.
