The white balance changes as time passes. A cause may be insufficient pressure welding and caulking of the connector lead pins on the RGB Signal Cable. Solution: Perform the following checks and procedures on the C Board (P/N A-1335-039-A). 1. Check the connections and contact surfaces on Connector P501, CRT Socket S501 and the (4) Corner Ground Screws. Clean the contact surfaces and reinsert these items. See figure below for reference.

If the problem persists, then do the following procedure to connect the RGB input signals directly to the C Board. See figure below. A. Note the pin locations of the lead wires from the RGB Video Cable to P501 and P502 Mating Connectors. B. Cut the lead wires where they enter the P501 and P502 Mating Connectors and remove P501 and P502 from the C Board. C. Solder the lead wires to the solder pads of the connectors.

Solution: Then, the DAS Ver. J1.1 EDID function can be used along with continuity checks to verify DDC circuit operations. Please perform the following procedures to verify DDC circuit operations. All check conditions given in the following procedures must be OK to verify DDC operation. Stop this procedure and troubleshoot the circuits if any check condition is not met. A. Check the EDID Field 1. Start DAS J1.1 2. Perform "Setup". 3. Select "EDID" mode. 4. Select "EDID EDITOR". 5. Select "OK", "OK". 6. Check the EDID Screen. This field should contain 128 words. Each word is 2 Hex digits between 00 and ff in value. Not all values should be either 00 or ff. 7. Select "CANCEL". Cont. Reference: DAS Ver. J1.1 PRINTED IN USA PRINTED ON RECYCLED PAPER Computer Monitors Service Bulletin No. 112 B. Check Video Connector Continuity The connections from the Video Connector to the DDC ROM are checked for continuity and shorts. 1. Remove all AC power and Video connections to the monitor. 2. Locate the Video Input and DDC ROM connections from the Service Manual. 3. Use an Ohmmeter or equivalent to verify continuity from the Video Connector Pin 9 to DDC ROM circuit HOST +5VDC if this option is implemented. Also check for no shorts between this path and other +5VDC busses and GND’s. 4. Verify continuity from the Video Connector Pin 12 to DDC ROM DATA (SDA) Pin. Also check for no shorts between this path and +5VDC busses and GND’s. 5. Verify continuity from the Video Connector Pin 15 to DDC ROM CLOCK (SCL) Pin. Also check for no shorts between this path and +5VDC busses and GND’s. The procedures to verify the DDC function are completed. If all check conditions given in Procedure A and B are OK then the DDC circuit functions are verified. ************************************************************************ Computer Monitors Service Bulletin Sony Service Company -Technical Services A Division of Sony Electronics Inc.
