Exactly as described, a Service Manual complete with the schematics and PCB layout delivered in a timely manner. Many thanks for the great service.

some of the writing is a bit blur but the part in the schmatic was great and i have fixed the machine thanks

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

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.

2-2-1 White Balance Adjustment
1. W/B Adjustment is required for the following four modes: DVI � DTV � PC � CVBS(VIDEO) � CVBS(VIDEO PIP) 2. Adjustment Method (DVI, DTV, PC : VG828, CVBS : Adjust RF signals to match the Toshiba pattern (in-house signal) ! Adjust the target set by adjusting the panel logic and the video DNIe adjustment register in register in order to determine the referential W/B of the panel with a DVI input, which is the full digital path. @ For DTV adjustment, adjust the adjustment register of ad9888 to align the DTV signal to the DNIe and logic panel value which was fixed with a DVI adjustment so that they are in effect considered to be the same signals. (At this time, do not adjust the gain of AD9888 � the Highlight W/B does not need to be adjusted since its deviation falls within valid distribution range.) # PC adjustment is same as DTV adjustment. (The offset can be applied to the values obtained through DTV adjustment. However, additional adjustment is required for Y, Cb, and Cr of DTV since PC processes R, G, and B signals.) $ cvbs adjustment is performed with the Toshiba pattern (in-house signal) and differs from the VG828 signals in the above three modes. Hence, it should be performed with the same method of ! DVI adjustment. % Finally, activate PIP in video mode, and repeat W/B adjustment. � Thus, Micom saves the W/B data separately for each memory mode of the block (See the block diagram given below) during W/B adjustment.
Micom can memorize the four modes separately. However, under the current adjustment guidelines, DTV and PC are memorized with the same value during DVI adjustment and CVBS is memorized with a separate value.
