The display frame assy has to be also replaced if the calibration values are lost by some other reason (e.g. after replacing the NOR memory chip D3000). If the phototransistor is changed, the calibration value in the phone memory has to be changed to the default value ‘1’.

RM-42 Camera Module Troubleshooting Nokia Customer Care 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 400
RM-42 Camera Module Troubleshooting Nokia Customer Care Sharpness Good quality images are 'sharp' or 'crisp', meaning that image details are well visible in the picture. However, certain issues, such as non-idealities in optics, cause image blurring, making objects in picture to appear 'soft'. Each camera type typically has its own level of performance.
PAGE 401
RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 80 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 usually cannot be avoided. The movement of camera or object sometimes cause blurring indoors or in dim lighting conditions because of long exposure time.
PAGE 402
RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 82 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 403
RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 83 Image taken against light Flicker In some occasions a bright fluorescent light may cause flicker in the viewfinder and captured image. This phenomenon may also be a result, if images are taken indoors under the mismatch of 50/60 Hz electricity network frequency. The electricity frequency used is automatically detected by the camera module.

PAGE 406
RM-42 Camera Module Troubleshooting Nokia Customer Care If a dust particle is lying on the infrared filter surface on either side, they are hard to locate because they are out of focus, and appear in the image as large, grayish and fading-edge 'blobs'. Sometimes they are invisible to the eye, and thus the user probably does not notice them at all. However, it is possible that a larger particle disturbs the user, causing need for service.
PAGE 407
RM-42 Camera Module Troubleshooting Nokia Customer Care A quantitative analysis of sharpness is very difficult to conduct in any other environment than optics laboratory. Therefore, subjective analysis should be used. If no visible defects (items 1-4) are found, a couple of test images should be taken. Generally, a well-illuminated typical indoor scene, such as the one in Figure "Good image taken indoors (Page )", can be used as a target.

A smeared fingerprint may be hard to see on the protective window but if will affect the image quality. These flares can be avoided by cleaning the window with a suitable cloth.

RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 91 Image of point light sources taken with a clean protective window Figure 92 Image of point light sources taken with a dirty (finger print) protective window Image bit errors Bit errors are image defects caused by data transmission errors between the camera module and the phone baseband and/or errors inside the camera module. Usually bit errors can be easily detected in images, and they are best visible in full resolution images.
PAGE 410
RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 93 Bit errors caused by JPEG compression One type of bit error is a lack of bit depth. In this case, the image is almost totally black under normal conditions, and only senses something in very highly illuminated environments. Typically this is a contact problem between the camera module and the phone main PWB. You should check the camera assembly and connector contacts.

RM-42 System Module Nokia Customer Care WCDMA receiver In the WCDMA mode, the received signal is fed from the antenna to the duplex filter. After the duplex filter the signal goes via balun to the integrated LNA residing in N7500. After the LNA, the signal goes trough an off chip band pass SAW filter. The main task of the filter is to attenuate the Tx signal which is leaking trough the duplex filter and amplified by LNA.

RM-42 System Module Nokia Customer Care Introduction to transmitter functionality Transmitter functions are implemented in the RF ASIC N7501. It contains a BB frequency low pass filter, which is tunable according to the signal bandwidth of the system in use. In addition, N7501 contains separate RF paths comprising a final frequency IQ modulator and VGA amplifiers. In order to eliminate the effect of process variations on the low pass filter characteristics, a tuning procedure is carried out in production.

RM-42 System Module Nokia Customer Care Another function of the detector voltage is to steer the DC/DC converter, which is providing a variable supply voltage for the WCDMA PA. WCDMA PA module WCDMA PA is housed in a separate module having • a variable supply voltage input for the amplifier stages (Vcc11), • a battery supply voltage for the bias circuits (Vcc12), • and two bias current inputs. Bias currents are generated by 5-bit DA converters in N7501 RF ASIC.

RM-42 System Module Nokia Customer Care The signal is first low pass filtered with filter corner frequency set to approximately 200 kHz. After the filter, the signal is routed to the GSM modulator. The appropriate routing after the modulator is selected by biasing either EGSM900 (/GSM850) or GSM1800/1900 variable gain amplifier. The amplifier gives 40 dB of power control dynamic range. After the VGA stage the signal exits N7501. In case of GSM1800/1900 the signal goes directly to the GSM PA module.

RM-42 System Module Nokia Customer Care and the power control voltage is kept constant by a capacitor integrated to N7501 Tx ASIC. When the active part of the burst is over, the loop is again closed and the power is ramped down. The TXA signal is disabled during GMSK transmission. Power control loop is enabled and disabled by writing an appropriate register in N7501 RF ASIC. In case of dual slot transmission, the output power is ramped down between the consecutive slots.

RM-42 System Module Nokia Customer Care The VCO frequencies are locked by PLLs into a reference oscillator, VCTCXO. The PLLs are located in N7500 and N7501 respectively and controlled via RFBus. PLL charge pump charges or discharges the integrator capacitor in the loop filter depending on the phase of the measured frequency compared to the phase of the reference frequency. The integrator output voltage is connected to the control input of the VCO.
