The purchased manual is an high quality scan of the original Philips paper-based Service Manual. I am very satisfied!
;
The purchased manual is an scan of the original Panasonic paper-based Service Manual. Unfortunately the contrast is not perfect, but I am satisfied anyway!
;
The purchased manual is an high-quality scan of the original JVC paper-based Service Manual. The Service Manual includes the Owner´s Manual, so you do not have to buy both of them.
;
It paid to find this Service Manual, couldn't find it anywhere else. Exactly what I wanted. Received within 24 hours.
;
Complete manual with clear schematic diagrams and printed circuit board layouts of two variants of the headset and the transmitter an old and a new version.
Also shows how the headset and the transmitter is opened and how transmitter and receivers can be adjusted and where to measure.
I had no problems to repair the headset using this service manual.
Belinea 101710 LCD Monitor Service Guide Chapter 1 Circuit Operation Theory
4.) Scaling IC: We use MX88L282 of Macronix and by its frame buffer function to process the digital RGB signals to maximum 75Hz refresh rate at 1280 by 1024 resolution(about 135MHz pixel rate), it also support a ratio expansion function to display a full screen when the resolution of input signals are less than 1280 by 1024. 5.) SDRAM: We use 3 pieces of 2M bytes SDRAM to be the frame buffer of the scaling IC to process maximum 1280 by 1024 resolution of 24 bits RGB data. 6.) MCU: We use Myson MTV112V to controls all the functions of this interface board, just like the mode detecting, OSD display setting, the adjustable items, adjusted data storage, DPMS control, the external RS232 communication and the scaling IC 7.) EEPROM: We use 24C04 to store all the adjustable data , and we divide it into two parts for the storage of factory settings and user settings. 8.) OSD IC: We use LSC3852 of Motorolla to do �On Screen Display� function. 9.) LVDS transmitter IC: We use two pieces of THC63LVDM83A of THine to transmit all the digital data to the LCD panel driver IC because this driver IC has two pieces of built-in THC63LVDM83A (LVDS receiver IC).
