6600 strange... - GSM-Forum

doktortelecom · 06-25-2005, 11:19

Hello, i received from a client a 6600 , first was only no network , i resolved the problem by replacing the exernal antenna connector, then the camera connector was unsoldered and i soldered by reheating, now the phone tries to start it lights the LCD, and keyboard and after 2 seconds the keyboard light -first and then the lcd goes dark -the phone shuts down.every time i power on the phone it happens this way.Any ideas?
remember the phone was ok when came to me, something happened when i was working on it.
thanks in advance.
regards, doktortelecom
P.S.:I have also to mention that i resoldered all major ICs from the mainboard:CPU, POWER-AUDIO IC, FLASHES , RAM...NOTHING CHANGED THE SAME DEFECT.

Yes i tried but no success.
Anyhow the phone is working now, i succeded to find the defect, It was the batery temp.controll on the mainboard(the one in the middle between + and-)a broken circuit leading to the cpu.
I decided to write sollution here for others to see sollution for this defect.
regards,
doktortelecom-no phone without a sollution.
