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 quality service manual. Quick processing, fair prices. Love to do business again. Thank you!!!

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!

Pitch: 5 mm Rating electrical power 1/4W � � � � � � � � � Chips resistors are 1/10W. All resistors are in ohms. : nonflammable resistor. : fusible resistor. ¢ : internal component, and adjustment for repair. : panel designation. All variable and adjustable resistors have characteristic curve B, unless otherwise noted. METAL FILM (:RN, :RN-CP) resistors in 1%, 0.50%, 1/4W unless otherwise specified. The components identified by in this basic schematic diagram have been carefully factory-selected for each set in order to satisfy regulations regarding X-ray radiation. Should replacement be required, replace only with the value originally used. When replacing components identified by , make the necessary adjustments indicated. If results do not meet the specified value, change the component identified by and repeat the adjustment until the specified value is achieved. (Refer to R1536 adjust on page 3-9, 3-10) � When replacing the part in below table be sure to parform the related adjustment.
