nokia 2650 no screen - GSM-Forum

kokosu · 03-06-2006, 19:25

I have a nokia 2650, and everything is working fine except the screen! Hearing and talking is very good!
So the talking is ok, I can call everyone I want, but I have to know the number!

)
There was a time when everything was ok with the screen, but for a very short period of time. And there was one more time, when the screen appeared rotated 180 degrees. Like I said, everything seems to be working fine, except the screen. I opened the phone and I looked inside of it. There is a flat cable that I have examined with a magnifying glass. I can't see any bad connections. Also I saw 3 blue leds on keypad that seems to not work. What do you think of this phone? I already took the service manual, and I am looking over it. I think that the flat cable should be the problem! thank you!

NEW PROBLEM!!!
I've just changed the flat cable, with a new one with sim connector and now the screen works, but it says INSERT SIM!
What did I do wrong? Please help!!!!!

So I looked twice on the flat cable, and there are missing 2 components. Near the speaker, not near the sim reader!

AND UP AGAIN!!!

Man this is the worst phone ever. I've tried 3 flat cables, now is working, but there is a problem:
With the original display, everything is seeing in the mirror. Now I have an display from an old 6610 I think, but this display has some black lines... I wish I can make the old display work, but I don't know what is wrong with it, it worked perfectly with the old flat cable, I did not changed nothing, I can put some pictures if you want...
What do you think it might be?
I tried the display on some broken 2600, but is the same mirror thing; it must be something with the display
