Philips EasyVision RAD 4.2: troubleshooting and error codes

The ServiceForge knowledge base holds 5 documented symptoms for the Philips EasyVision RAD 4.2, with 10 ranked causes, 11 diagnostic checks with test points and expected values, and 0 error codes. Each symptom below shows its causes and the first check; the rest is one connection away. Connect ServiceForge to your AI

Symptoms

Calibration: Density verification

Verify measured density values are within acceptable tolerance of target density during calibration

Ranked causes

1. Printer calibration drift (occasional)
2. Densitometer malfunction or misalignment (occasional)
3. Incorrect calibration data entry or calculation (occasional)

First check

Measure density value at grey level

Test point: Target density (DT)
Expected: Measured density (DM) within 5% of DT plus 0.02 offset

1 more check with pass and fail actions, 3 corrective actions, and part numbers are in ServiceForge. Connect ServiceForge to your AI

Calibration: Divergence calculation and density verification

Measured optical density values fall outside acceptable tolerance range during calibration verification

Ranked causes

1. Printer own calibration out of tolerance (common)
2. Densitometer not operating correctly (occasional)
3. Incorrect calibration values or calculations (occasional)

First check

Calculate tolerance range for target density

Test point: Target density (DT) value
Expected: Range = DT ± (5% DT + 0.02)

Calibration: Monitor brightness and contrast

Monitor brightness and contrast settings require adjustment after system configuration and before clinical use. Procedure uses test images to set optimal display parameters.

Ranked causes

1. Factory settings not configured for optimal display (common)
2. Dual monitor brightness perception mismatch (occasional)

First check

Monitor warm-up time

Test point: System power-on
Expected: At least 30 minutes elapsed with no screensave operation

Calibration: Pixel size calibration setup

Configuration of hard copy pixel size calibration parameters for imaging workstation

Ranked causes

1. Printer selection mismatch (unknown)

First check

Verify correct printer is selected

Test point: Printer selection setting
Expected: Same printer as used in density calibration

Test image access

Test images for printer calibration must be loaded from protected area into local database for monitor adjustment procedure.

Ranked causes

1. Test images not loaded in local database (unknown)
