Problem
|
Possible Cause
|
Solution
|
| NO AUDIO I/O (ANALOG) |
(1) No Linear Power Supply output. |
(1) Verify voltages are present at J3 (+15vdc, -15vdc,+5vdc). If not, check fuse
on supply. If fuse is ok, R/R Linear Power Supply.* |
| |
(2) Defective IRP main board. |
(2) R/R IRP main board.* |
| UNIT WON'T RECORD |
(1) Disk is full. |
(1) Erase cuts to make room on the disk for recording. |
| |
(2) Disk generates errors due to fragmentation. |
(2a) Set REC LIMIT to any value (except none) to work around fragmentation problem.
(2b) Perform the Instant Replay DEFRAG utility.
(2c) Backup material, reformat drive. |
| |
(3) Disk generates errors due to other factors. |
(3) R/R hard drive.* |
| |
(4) Defective IRP main board. |
(4) R/R IRP main board.* |
| BLINKING CURSOR AT POWER UP |
(1) SIMM module jarred loose. |
(1) Reseat SIMM module in IRP main board receptacle. |
| |
(2) Defective IRP main board. |
(2) R/R IRP main board.* |
| NO POWER |
(1) AC line voltage not present. |
(1) Check AC line input levels from outlet. |
| |
(2) Blown Switching Power Supply fuse. |
(2) R/R fuse. |
| |
(3) Bad power supply connection(s). |
(3) Use ohmmeter to check connections.* |
| NO DIGITAL I/O |
(1) Wrong CONFIGURATION values set. |
(1) Refer to manual and set digital I/O values accordingly. |
| |
(2) Defective cables. |
(2) Replace cables with known good ones. |
| |
(3) Defective IRP main board. |
(3) R/R IRP main board.* |
| DEFRAG ERRORS |
(1) Corrupt cuts. |
(1) Delete and re-record cuts that hang up DEFRAG. Errors that end with a three digit
number (i.e. 003) indicate that cut is bad. |
| |
(2) Unit needs software upgrade. |
(2) Order Instant Replay field upgrade kit or send unit to 360 Systems.* |
| |
(3) Defective hard drive. |
(3) R/R hard drive.* |
| UNIT WON'T ACCEPT DIGITAL AUDIO |
(1) Changes in digital channel status |
(1) Try starting SOURCE unit before pressing PLAY on recording unit. Putting SOURCE
unit in PAUSE mode (instead of STOP) also works.* |
| BACKUP FUNCTION FAILS |
(1) Wrong I/O ports used. |
(1) XLR (AES/EBU) ports MUST be used. |
| |
(2) I/O cables are transposed or miswired. |
(2) Verify cable routing and/or wiring.* |
| NO DISPLAY |
(1) Defective display cable |
(1) R/R display cable.* |
| |
(2) Defective Display Module. |
(2) R/R Display Module.* |
| "BUZZING" HEADPHONE NOISE |
