1998014en.pdfTECHNICAL INFORMATION Chassis concerned : R6000 - R7000 Model equipped with LL' Standard only Subject : Improving the response of the Automatic Gain Control circuit. Symptom / Problem observed : Picture flashing. Cause : Response time of Automatic Gain Control circuit too slow when receiving strong signals. Solution implemented : Change the value of capacitor CI050 from 100nF to 56nF +/- 10% 16V, Part No. 20703690.
1998021en.pdfTECHNICAL INFORMATION Finished products / Chassis concerned : R6000 according to the attached list. Symptom/ Problem observed : In any mode of operation the VCR can switch itself "OFF" and enter the security mode (locked), once in this mode none of the front panel key functions will respond. Solution implemented : In the case of repetitive failures it is now possible to change the software at the same time as the EEPROM. The new software (OTP technology) will prevent this failure happening again, the appropriate version with its reference number is given in the table for each group of products. In few months we will have a special EEPROM that will cure the problem of locked VCR's, thereby making replacement of the micro processor unnecessary. For this reason we recommand that the micro processor is not replaced at this stage. IRIS CODE : The code mentioned below must be used to report the failure in the warranty sheet. to make your report easier and more reliable. Condition/ Symptom
