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!

Assy/Panel Removal
Rear Cover Warning: Disconnect the mains power cord before you remove the rear cover. 1. Remove the screws, which secure the rear cover. The screws are located at the top, bottom, left and right sides; next to the Side/IO connections and SCART connection. There are also three deeper located screws next to the stands. 2. Lift the rear cover from the cabinet. Make sure that wires and flat foils are not damaged during cover removal.
1. Remove the middle fixation screw (1) from the bottom side of the connector plate (as this holds the SSB bracket). Note: Sometimes it is easier to loosen the complete connector plate and remove it together with the SSB. 2. Remove all connector fixation screws (2) from the front side of the connector plate. 3. Remove the two female screw locks (3) of the VGA connector. 4. Release the plastic cable clips (4) on the shielding and disconnect all cables from the SSB. Note: Be careful with the fragile LVDS connector on the SSB. 5. Now, completely remove the SSB (together with all the shieldings) from the set. 6. Once the SSB is out, remove the fixation screws (5) from the shielding. 7. Remove the shielding, it hinges at the left side (acc. photo). 8. Remove the fixation screws that hold the panel, and take out the panel. Notes: � Pay special attention to the EMC foam on the SSB shielding. These must be replaced in their initial positions � during set re-assembly. Insulate the tuner pins, so they cannot touch the shielding (see also figure �SDM Service jumper� in Chapter 5).
