RM-465 RF Troubleshooting General RF troubleshooting Introduction to RF troubleshooting Most RF semiconductors are static discharge sensitive ESD protection must be applied during repair (ground straps and ESD soldering irons). Measuring equipment All measurements should be done using: • An oscilloscope for low frequency and DC measurements. Recommended probe: 10:1, 10Mohm//8pF. • A radio communication tester including RF generator and spectrum analyser, for example Rohde & Schwarz CMU200.
PAGE 112
RM-465 RF Troubleshooting Auto tuning Introduction to RF tunings RF tuning is always performed with the help of a product-specific module jig, never with an RF coupler. Using an RF coupler in the tuning phase will cause a complete mistuning of the RF part. Cable and adapter losses RF cables and adapters have some losses. They have to be taken into account when the phone is tuned. As all RF losses are frequency dependent, the user has to act very carefully and understand the measurement setup.
PAGE 114
RM-465 RF Troubleshooting Receiver Troubleshooting Introduction to receiver (RX) troubleshooting RX can be tested by making a phone call or in local mode. For the local mode testing, use Phoenix service software. The main RX troubleshooting measurement is RSSI reading. This test measures the signal strength of the received signal. For GSM RSSI measurements, see GSM RX chain activation for manual measurements/GSM RSSI measurement. For a similar test in WCDMA mode, see WCDMA RSSI measurement.

RM-465 Camera Module Troubleshooting Introduction to camera module troubleshooting Background, tools and terminology Faults or complaints in camera operation can be roughly categorised into three subgroups: 1 Camera is not functional at all; no image can be taken. 2 Images can be taken but there is nothing recognizable in them. 3 Images can be taken and they are recognizable but for some reason the quality of images is seriously degraded, or customer complains about image quality.
PAGE 128
RM-465 Camera Module Troubleshooting Sensitivity Camera module's sensitivity to light. In equivalent illumination conditions, a less sensitive camera needs a longer exposure time to gather enough light in forming a good image. Analogous to ISO speed in photographic film. Sharpness Good quality images are 'sharp' or 'crisp', meaning that image details are well visible in the picture.
PAGE 129
RM-465 Camera Module Troubleshooting Figure 31 Blurring caused by shaking hands Movement in bright light If an image is taken of moving objects or if the device is used in a moving vehicle, object 'skewing' or 'tilting' may occur. This phenomenon is fundamental to most CMOS camera types, and may happen when using the electronic shutter. The movement of camera or object sometimes cause blurring indoors or in dim lighting conditions because of long exposure time.
PAGE 130
RM-465 Camera Module Troubleshooting Figure 33 Noisy image taken in +70 degrees Celsius Phone display If the display contrast is set too dark, the image quality degrades: the images may be very dark depending on the setting. If the display contrast is set too bright, image contrast appears bad and "faint". This problem is solved by setting the display contrast correctly. This is normal behaviour; do not change the camera module.
PAGE 131
RM-465 Camera Module Troubleshooting Figure 35 Flicker in an image; object illuminated by strong fluorescent light Bright light outside of image view Especially the sun can cause clearly visible lens glare phenomenon and poor contrast in images. This happens because of undesired reflections inside the camera optics. Generally this kind of reflections are common in all optical systems. This is normal behaviour; do not change the camera module.

RM-465 Camera Module Troubleshooting Testing camera image sharpness Symptoms and diagnosis If pictures taken with a device are claimed to be blurry, there are five possible sources for the problem: 1 The protection window is fingerprinted, soiled, dirty, visibly scratched or broken. 2 The camera module has failed to focus correctly, producing a blurred image. 3 User has tried to take pictures in too dark conditions and images are blurred due to handshake or movement.
PAGE 135
RM-465 Camera Module Troubleshooting the fault is probably in the camera window. Check the window by looking carefully through it when replacing the module. As references Figure "Good image taken indoors" and Figure "Good image taken outdoors" can be used. Another possibility is to use a service point comparison phone, if available. Effects of dirty or defective camera lens protection window The following series of images demonstrates the effects of fingerprints on the camera protection window.

RM-465 Camera Module Troubleshooting Figure 44 Enlargement of a hot pixel Flash photography problems Use of flash device may affect the image in many ways. • White balance errors. The image may get a wrong tone due to mixing of flash colour temperature and ambient lightning. This is unwanted but normal feature. • Dust reflections. Dust or water drops in front of the flash unit may reflect strongly to the camera sensor. See the following figure.

RM-465 Camera Module Troubleshooting • If main ST_CAMERA_IF_TEST or ST_CAMERA_AUTOFOCUS_TEST fails, check connector X1451 and change camera flex (2). • If ST_SEC_CAMERA_IF_TEST fails, change UI flex and dynamic flex. Check also the flex connectors. • If ST_LED_FLASH_TEST fails and flash led does not flash, change AV flex and check the connector X1451. Note: Note that dim white flash is seen during still imaging even when the flash is manually turned off.
