RM-340; RM-341 Baseband Troubleshooting Instructions General baseband troubleshooting Key components Power supply test points Phone cannot be powered on (I) Context This means that the phone does not use any current at all when the supply is connected and/or power key is pressed. It is assumed that the voltage supplied is 3.6VDC. The UEMCLite will prevent any functionality at battery/supply levels below 2.9VDC. Issue 1 COMPANY CONFIDENTIAL Copyright © 2007 Nokia. All rights reserved.

RM-340; RM-341 Baseband Troubleshooting Instructions Phone cannot be powered on (II) Context If this kind of failure is presenting itself immediately after FLALI, it is most likely caused by ASIC's missing contact with PWB. If the MCU doesn’t service the watchdog register within the UEMCLite, the operations watchdog will run out after approximately 32 seconds. Unfortunately, the service routine can not be measured.
RM-340; RM-341 Baseband Troubleshooting Instructions Phone cannot be flashed Context The flash programming can be done via the pads on the PWB (J2060). If failed, then follow up the trouble shooting flow chart. In case of flash failure in the FLALI station, swap the phone and send it back to the care program for further analysis. Possible failures could be short-circuit of balls under µBGAs (UEMCLite, UPP4M, FLASH), or missing or misaligned components.

RM-340; RM-341 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.
RM-340; RM-341 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.
RM-340; RM-341 Camera Module Troubleshooting Figure 91 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. This is normal; do not change the camera module.
RM-340; RM-341 Camera Module Troubleshooting Temperature High temperatures inside the mobile phone cause more noise to appear in images. For example, in +70 degrees (Celsius), the noise level may be very high, and it further grows if the conditions are dim. If the phone processor has been heavily loaded for a long time before taking an image, the phone might have considerably higher temperature inside than in the surrounding environment.
RM-340; RM-341 Camera Module Troubleshooting 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. In some very few countries, both 50 and 60 Hz networks are present and thus probability for the phenomenon increases.
RM-340; RM-341 Camera Module Troubleshooting Examples of good quality images Figure 97 Good image taken indoors Figure 98 Good image taken outdoors Camera construction This section describes the mechanical construction of the camera module for getting a better understanding of the actual mechanical structure of the module.

RM-340; RM-341 Camera Module Troubleshooting Figure 100 Camera module bottom view including serial numbering The camera module as a component is not a repairable part, meaning that the components inside the module may not be changed. Cleaning dust from the front face is allowed only. Use clean compressed air. The camera module uses socket type connecting. For versioning, laser marked serial numbering is used on the PWB. The main parts of the module are: • Lens unit including lens aperture.
RM-340; RM-341 Camera Module Troubleshooting In Service software press “Read”, and the Camera Configuration window shows available DCC data file name and its version to upload. If the previous camera configuration was the same as installed, then Current Configuration Version displays DCC data version currently in the terminal memory, otherwise it shows xxx.xxx. Press “Upload” and then the DCC data settings are updated.
RM-340; RM-341 Camera Module Troubleshooting Figure 102 Effects of dust on optical path If large dust particles get trapped on top of the lens surface in the cavity between camera window and lens, they will cause image blurring and poor contrast. The dust gasket between the window and lens should prevent any particles from getting into the cavity after the manufacturing phase. Dust in this position should be blown away by using compressed air.
RM-340; RM-341 Camera Module Troubleshooting 5 The protection window is defective. This can be either a manufacturing failure or caused by the user. The window should be changed. 6 The camera lens is misfocused because of a manufacturing error. 7 Very high level of digital zoom is used A quantitative analysis of sharpness is very difficult to conduct in any other environment than optics laboratory. Therefore, subjective analysis should be used.
RM-340; RM-341 Camera Module Troubleshooting Usually bit errors can be easily detected in images, and they are best visible in full resolution images. A good practice is to use a uniform white test target when analysing these errors. The errors are clearly visible, colourful sharp dots or lines in camera images. See the following figure. Figure 105 Bit errors caused by JPEG compression One type of bit error is a lack of bit depth.
