Nokia 6610 Power Switch Problem

Phone Repairing this time again will share experiences in repairing the damage Power Switch on the Nokia 6610 mobile phone.
Symptoms of damage to the Nokia 6610 mobile phone this time are: Mobile to die, but when connected to the transformer charger, can charge mobile phone battery.
This indicates that the mobile machine is still working, but the phone can not be turned on because of any damage or problems on the power switch. The first step I did was make a visual inspection. This is done to ensure that no chip is missing either due to collision and so on. Having ascertained that no chip is lost or separated, then the next analysis was to examine whether the PCB track is broken or not. In this examination step, I do not find a damaged PCB track, but instead there is the resistance value of resistor which does not match that should be. R306 chip is as shown in the following figure:

To repair this damage, we can replace the resistor with the same value as shown in the diagram scheme. However, if we do not have a resistor, we can handle it by doing jumpers from switch on / off straight to the point of resistors that is connected to UEM IC. The picture as shown below:

Pm Files for Nokia DCT-4

Contact service can occur for several reasons. One reason mobile experience Contact Service is due to the destruction of pm files on mobile.
Here I share some pm files for mobile phones Nokia DCT-4 which consists of the Nokia 1110, Nokia 1112, Nokia 1600, Nokia 1650, Nokia 2310, Nokia 2610, etc.
Before writing this, I've also written about how to overcome the damage Contact Service on the Nokia 5510 mobile phone. In such cases, Contact Service actually is caused by damage to the CCONT IC.
Further back, I also have written about ways to overcome the damage Contact Service on mobile phones Nokia DCT-3. Okay, please download it pm file for Nokia mobile phones that I mentioned above, may be helpful.

Nokia N73 Handsfree Problem

Some time ago, there was a problem that very rarely happens. Actually, if this can be called stupid. Why do I say stupid? Here's the story:

Mobile that I use the Nokia N73. When I came home from a relative's house, then I put the phone on the table. Without my knowledge, my brother took my Nokia N73. He intended to listen to music through a hands-free but without him knowing it, he took the hands-free for Sony Ericsson W395 mobile phones.

When handsfree Sony Ericsson W395 is we put on the Nokia N73, is entered. But because the system does not detect the same, finally on my phone there is always a warning enhancement not supported.

Because I do not know the chronology of the beginning, I thought it was caused by a virus that damage the operating system. I think that because I often browse and download using the phone.

When I try to restore the phone settings to factory settings, it turns out that the warning is still there. Finally, after my in-depth analysis, I have concluded that to eliminate these warnings, we must install a suitable handsfree. Finally, after I install a suitable handsfree, especially the original, mobile phones back to normal.

Nokia 2100 Signal Drop

After a long time not writing, this time I want to share about how to improve the signal problem on the Nokia 2100 mobile phone.

I found the problem this time is as follows:

When I first turned on, cell phone signal can be captured but a few seconds later the signal was lost immediately. I tried to find signal manually from setting menu, the result can detect any mobile cellular networks there. I thus conclude that the RF processor is not a problem.

Next I checked the Power Amplyfier. I pull the IC Power Amplyfier then I replace it with new. The result was still missing signal abruptly.

After I did some earlier, I finally have the conclusion that the damage occurred on the passive components in the vicinity of IC Power Amplyfier. After I check one by one, finally I found a damaged passive components, namely the capacitor C 760.

Location of these components can be seen in the picture below. After I replace these components, mobile phone back to normal.

Nokia 8310 Mic Problem

The information we give this time is the information about the Nokia 8310. On the Nokia 8310 mobile phone is often a problem occurs in Microphone.
Problems with microphone can be caused by a broken line or a broken microphone. However, these days we have received 3 pieces Nokia 8310 mobile phone. Complaint is when to call, our voice was not heard by the other person.
At first we thought that the microphone is broken, but after we checked, still a good microphone. The next step we check the microphone channels, the result no broken lines.
It turned out after our study, the damage caused by installing the bolts on the mobile cracked bone, so that when we tighten the bolts, the PCB board is not attached properly due to loose bolts. This causes the connection between the microphone with the PCB board to be not perfect.
To fix this, replace bone or you can provide the lead on the microphone on the PCB. This is a simple step but provides a real solution.
