This will require the adjustment of the camera and optical sections. Instead of rewriting the entire default data, edit the following EEPROM addresses for the recording current characteristics according to the color of the drum stator installed: Address Beige/NEC Black/Alps 1D0h 60h D0h 1DCh 60h D0h 1DDh 60h D0h This bulletin is issued as an aid for service personnel maintaining this product.

Digital Video Camera Service Information JVC Service and Engineering Company of America Engineering Department ® A Division of JVC Americas Corp. 10 New Maple Avenue Pine Brook, NJ 07058 Model: GR-DVM80U, GR-DVM90U SB-02060502-V _______________________________________ Number: ______________ June 2002 ______________ Power turns off automatically after replacing the Main PWB Subject: _______________________________________ Date: Symptom: When the MAIN PWB assembly on the above listed units is replaced, power might be turned off after the old EEPROM data is written into the new MAIN PWB assembly. Cause: The adjustment value (data contained at EEPROM address 1D3h) is incorrect for this board and prevents the unit's 81MHz VCO from being locked by the PLL to the main clock. The camera CPU senses that the 81MHz VCO is not PLL locked and turns off the unit's power. Solution: Perform the following procedure using the camera's service support software (YTU94057-48). 1. Set the power switch to "AUTO". *Although the power is turned off, communication with the service support software is still possible. *If the EEPROM data is read using the EEPROM utility, there is no problem even if all the data displayed is "00h". 2. Using the EEPROM utility, change the data at EEPROM address 1D3h to "A5h". 3. Reset the power switch to "AUTO". The unit's power should turn on. 4. Perform the 81MHz VCO center frequency deck adjustment. This bulletin is issued as an aid for service personnel maintaining this product.

Cause: FPC of Drum Assembly is not properly connected (loosely connected or not straight connected) to CN4003 (M12D6S series) / CN202 (M14D6S series) on MDA board. Solution: 1. Peel the Reinforcement sheet (white area) off the Drum FPC from the edge of the drum side as pictured below. This bulletin is issued as an aid for service personnel maintaining this product.

It must be inserted in straight and must not be loose. 4. Stick a stick sheet on the connector and the FPC. This is to prevent a loose connection. Stick Sheet Part No. YTU96034 4. The Drum FPC must be folded in between the Mechanism and MDA as shown below. Note: The stick sheet is not pictured here. When inserting the Drum FPC, be sure to use the stick sheet as shown in step 4 to prevent a loose connection.

YMA0025xx), a tape may get jammed. Then, an emergency code "E03" is displayed. Cause: The cassette does not rest properly in the mechanism when it is inserted as shown below. The tape gets stuck due to an incorrect alignment with the Reel Disk Mechanism.
