Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
best regards

I will definitely be back for more information when I need it.

The service manual when downloaded and printed out was clear and easy to read. I would have liked to have been able to enlarge some details, but this was not possible as the file permissions did not allow this. The service was very good. The time taken from placing my order to downloading the document was only a few minutes.

The manual is useful for trouble shooting for an old instrument. It saved money,and let me enjoy DIY.
;
Perfect source of information for replacing the HDD and performing general diagnostics.

SET-UP ADJUSTMENT
s The following adjustments should be made when a complete realignment is required or a new picture tube is installed. Perform the adjustments in order as follows : 1. Color Purity 2. Convergence 3. White Balance Note: The PURITY/CONVERGENCE MAGNET assembly and rubber wedges need mechanical positioning. Refer to figure 1. Mounting position of the purity magnet assembly should fit to same position as old one because slightly difference to the position depend on a kind of tube.
*
There are no adjustment of purity and convergence in some picture tube (Unified with purity magnet)
SPECIFIC INFORMATIONS GENERAL ADJUSTMENTS
COLOR PURITY ADJUSTMENT NOTE : Before attempting any purity adjustments, the receiver should be operated for at least fifteen minutes. 1. Demagnetize the picture tube and cabinet using a degaussing coil. 2. Set the brightness and contrast to maximum. 3. Use a green raster from among the built-in test signals. 4. Loosen the clamp screw holding the yoke and slide the yoke backward or forward to provide vertical green belt (zone) in the picture screen.
5. Remove the Rubber Wedges. 6. Rotate and spread the tabs of the purity magnet (See figure 2.) around the neck of the picture tube until the green belt is in the center of the screen. At the same time, enter the raster vertically. 7. Slowly move the yoke forward or backward until a uniform green screen is obtained. Tighten the clamp screw of the yoke temporarily. 8. Check the purity of the red and blue raster.
