yeah good idea i will try a new battery - but you sure it won't be an internal hardware fault? the battery can last 2 or 3 days

and no it does not only appear when i charge the phone up, when i have it on standby usually

[sergo_zmeia]

What I mean is when the battery get low /one bar as You said/ and You put the charger in the problem persist or no?...If no I guess its battery broblem /low capacity/..but check with other one to be sure ...

It could also be a charging controller (located in the fone) failure :(

ok been using the phone for a bit now, when i do charge the phone it has fullsignal but when i don't it has no signal, now it happens on one or two bar

any suggestions?

First run a test with Eepromm tools 3.1 oor 4.0 /I personaly prefer 4.0/
It will give You a point to start....If the test is good You have a hardware problem with the RF part..

Try bridging L751 or L752 as the inductor may have collapsed and cannot get enough current to the p.a. when the battery is low.If not ,reflow top end of hanset as a capacitor may be failing or the p.a. or diplexor may be experiencing dry joint probs and losing current or building up too much resistance 8-)

When i make a test there is some lines with "passed" and other one with "not executed"
"Not executed" signify that there is a problem?

[sergo_zmeia]

Mr. way3000 do You find a solution for this drop signal problem also tell me please does the phone switch of when You making a call on one bar of the battery..
Mr. bleck there must be 5 positions " not executed"...then the test is good...
Thanks and regards!

Thank you very much Sergo, only a detail: are the 5 positions only the same?

[sergo_zmeia]

Mr. bleck if the software is good the positions are always the same..

sorry for the late reply! anyway no i didn't find a solution to fixing this error and i sold the phone on, i tryed changing batterys and differnet flashes
i was guessing it was an hardware fault but did not try to change anyhting as i am not very good with the 8210 hardware

[sergo_zmeia]

Strange thing....I found out that this problem exist in 33xx series too..
I tried new flash, change PA but no result...ok...the PA gets power directly from the battery...so when the phone switches of I guess that the battery voltage drops under 3.5V ...May be the soluthion realy is changing CCONT but I cant explain this to my self?!....for me the problem stays in RF part....Any coments of this...
Regards!
