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

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!
