Fully functional usable service manual. Considering the age of the manual and device quality was better than expected
 ;
Thank you very much, I've been very happy to find this manual on "Owner Manual". It's a perfect copy and it has been really useful for my work!
;
It took about 24-hours after my payment before I was able to get to the download. Apparently, payment processing is not 100% automated. That is no big deal, just be aware of that going in.
After I got to it, it was in good shape, easy to read, etc. Not some cheap FAX copy looking thing.
Also, this site was the cheapest I found. Another Plus!
;
Good price, very legible manual, exactly what I needed -- but had to wait a day to actually get the download of the manual. Would have preferred to download it immediately after payment rather than waiting for someone to "process" my order. I was surprised that I had to wait that long.
;
As the only source for this manual it rather rank quite high since it is well scanned and perfectly readable.
Replacement of ICs
1. Using the braided wire, �SOLDER TAUL� (Sony Part No. 7-641-300-81), remove the solder around the pins of the IC-chip to be removed. 2. While heating up the pins, remove the pins one by one using sharp-pointed tweezers. 3. Make sure that there is no pattern peeling, damage and/ or bridge around the desoldering position. 4. After removing the chip part, presolder the area, in which the new chip part is to be placed, with a thin layer of solder. 5. Place new chip part in the desired position and solder the pins.
2. Insert the tool tongs into the slots of the carrier socket. Push fully in so that the tool butts on the socket at �A�.

4-7-3. Removal of PLCC IC (IC701/DPR-86A Board)
PLCC socket Extraction Tool (Sony Part No. J-6035-070-A) This extraction tool is useful for extracting the IC(PLCC type) inserted into an IC socket, and fits all sizes of ICs from 20 pins through 124 pins.
3. Place the thumb and the first and second finger on the ribbed area of the tool. Maintain a small downwartd force to keep the tool butted on the socket. Squeeze the thumb and finger together so that the tool legs tend to straighten. This action will draw the chip carrier out of the socket and grip it within the tool legs. Maintain the squeezing action so as to hold the chip in the tool, hold the tool over your other hand and relax the squeeze. The chip will fall out of the tool and into your hand.

NOTE: Do not try to pull chip carrier out of socket and let the tool action pull it out. Do not squeeze harder than necessary, only enough that the tool action occurs.
<How to use the Extraction Tool>
