This service manual helped me to repair my PIONEER. Iam very satisfied, that I found it here.
Even the price of manual was not so high that person would not be able to spend a few money.
But that is very worth spent money. Thanks

Excellent service manual, the only known point of note is the alignment of improvability scanned pages within the pdf page. The resolution is good.

Sweet! I won the item on eBay and couldn't adjust the geometry or even keep a steady picure. This guide has the full schematics (not available anywhere else as far as I could tell), and was a bargain for the wealth of knowledge it contains. I hooked it up to my testing equipment, tweaked a few potentiometers and got it playing videogames in no time. Thanks!
