Recently, I found my Ericsson phone always sometime displays "NO ACCESS", even signal is very strong, cannot make or receive call, when I turn it off, and turn on again or re-search network, it gets access again.
My T18, i888 world, T28 world, R380 world is in same problem, but when I switch to any Nokia phone, everything is fine!
I saw another article from somewhere, another customer complains, Ericsson phone always displays "NO ACCESS" in another network, Nokia phones never have this problem! I believe this is Ericsson phones common problem!
Who knows what's wrong in Ericsson phone

Hi supergsm
Yes ericsson have this common problem.Like full bar 3-5 sec no network 3 sec full bar.Ericsson have this problem long time ago.Pf768 ver.9905 have this problem.When ericsson launch a1018,t1x have this problem already.Many user complain.
Here is the solution maybe can help you.
1/use hot air to flow rf parts.
2/change p.a.
3/load software [most common] find good eeprom file and flash file at 1 same phone and write to the phone.
Try this maybe can help you.
I mostly try 1 and 3.
Regards. :D :eek: :) :p :cool:

It seems not is EEPROM problem, all these phones are brand new, never been changed (or unlocked).

Hi!
No acces on Ericsson phones means that TX is not working!
On T2x problem is in bad soldered or bad PA,bad RF processor (11033C1D on T28,30042C2C on T20),bad RX/TX mixer (40307/1)...
There is more options for repair,but these are common...
Similar on old phones,too!

I dont know anything about phones
so if someone can explain to me what
RF,PA,TX means
and it seems that if i replace the RF processor it might solve my NO ACCESS
problem,
and one more thing, even though the phone says NO ACCESS, the signal bar seems to be working?(cos it changes once in while)
so where can i get a RF processor? and can this be done easily by myself or do i have to goto a technician to solve this?
any help will be greatly apreicated

PA is ower Amplifier
TX is Transmit
RX is Receive ....
Yes, changing RF processor would probably help in your case.
There are many companies that sels spare parts, but i don't think it will be easy to find someone who will sold you just one piece of RF procssor.
To change it you must have experience in BGA soldering, which i think you don't have correct me if i am wrong).
So, it is better for you to take your phone to some service stre to do it for you!
Go to an service or shop who has an GSM tester to run test on that phone, they will give you an raport with the faulty, TX or RX problem.
Also if the networks has barred the phone IMEI or SIM card this can be an problem.
