Thanks Jas. That information will help. I can see how a faulty power amplifier or power switching stage could cause this problem but I cannot see how by making a call it forces the amplifier or switching stage back online. But its the closest I have seen to a reasonable explanation. I recently had over 19 days of apparent normal use and then the fault started again. Typically my T68m(i) would develop this fault every couple of days sometimes twice in the same day. So it has to be the intermittent failure of some component rather than a network fault.

I have two T68m(i)'s that have the same problem and an R520m. I know of at least two other R520m and T68m that exhibit this behaviour and there has been reference on this forum to this problem so I am coming to the conclusion that there has to be a faulty batch of come component that is common to both R520m and T68m.

In my case, the fault happens both in an area that has good service levels and poor levels i.e. 5 bars and 1 bar. It seems to be independant of signal strength but the signal strength indicator on the T68's are not very accurate. The fault does not clear when you make a GPRS connection but always clears when you send an SMS or make a call. Without knowing what the inside of the handset looks like its hard to understand what area is failing based on the behavior that is exhibited.

I will discuss this with my service centre and see what they have to say.

Cheers Mike

Mike, froddan: I called the servicepoint today and got the name of the circuit: N400. The tell tale sign of my problems was not so much the 30% missed calls as the problems when trying to make a call. I counted the times I could get through at the first try and I think it was less than 50% of the times. (It is documented somewhere on Esato.) After the repair: 100%. How do yourphones behave in this respect?

Thanks Jas. I'll pay a visit to my SC as soon as I can, and have them
check that.
I have about that rate on my outgoing calls too, 50% not connecting.
But now I can specify the part for them to check

Thanks Jas. N400, I will follow that up. I never had a problem making calls only receiving them. Well come to think of it I do recall the occasional failed outgoing call but they are few and far between. However the incoming call fail rate is very high when GPRS and GSM is selected but the calls always get through when GSM Only is selected as the Preferred Service. One would have thought that the GPRS and GSM transmission paths would have been the same and both would use the N400 component but perhaps not. Its certainly worth following up.

Out of interest, have any of you noticed that the Cell Information no longer displays when using R2E006 in the upgraded T68m. Mine only displays after bootup until a call is made. Then it shuts down. Well that is how it has been for me up until yesterday. Today the Cell Site name has appeared on screen almost all day. Explain that away...

Cheers Mike

@ryan: I don't think this is a problem you should accept. My old t68m worked perfectly after the repair and my new t68i has never had the problem. Go to the service center and explain your problem to a technician. Refer to this correspondence if necessary.

It is good to hear that I'm not alone with this problem. Annoying it is. However, I have never any problem with making calls, so I don't know if the hardware problem is the same as the one solved problem of jas.
Another problem is that I lost my phone in a lake earlier this summer, so I guess that my varranty has disappeared. Just to mention it, the problem was present before the phone swim, and also before I updated the software from R2M to R3B.

just to chip into this discussion, i had a t28 for a while which developed a fault after i'd had it for a couple of weeks. it would just turn itself off at random times and pretty much everytime i tried to make a call or send an sms. apparently it was a problem with power accumulation or something. anyway, it got replaced - not repaired, so it must have been a pretty serious fault. apparently this was quite common on the t28.

maybe ericssons quality control department are a bit shit or something.


@bobahiom, are you in Hull UK? cos i am.

Well I mentioned the N400 component failure to the local SE people and they still believe that the failure to receive calls is a Network issue which they are trying to resolve. The interesting thing is that the fault develops because the handset fails to renew its registration with the Cell switch. So if puzzles me why SE think that its a network problem. Surely that fault has to be in the handset.

Like others I have never had any trouble making calls. Even when the receive fault is present, initiating a call simply forces reregistration and the T68m(i) starts to work normally until the next failure. I suspect that more people have this fault than is realised. It only comes to light when you start to question why you are getting voicemail notifications immediately after making a call and its the only call you made all day.

The more people that look for this fault the better.

Hello!

Iīve got the same kind of problem:
I use two different sim cards from two different operators.
When I use one card, the phone works fine. The other card inserted, I canīt receive a calls when the phone has been unused for a couple of minutes. However it doesnīt bother me much since I use this sim only for GPRS since this operator offers it for free.
Itīs just for information.

@Epedemic. Can you ellaborate on the base stations. Perhaps I can try and find out. It would help if I could perhaps mention some types of base station in case they have no idea what I am talking about (which in this case is true)...
