hey mate

i had the same prob with my k850 too. It's the LCD ribbon that runs under the keypad. If u press the a button on the keypad the LCD goes black, after a while when the keypad light is off, the LCD lights up again. I had my LCD replaced coz it didnt lit up anymore. Urs is still good so i think u wanna put something under the ribbon so it doesnt conflicts with other parts.


p.s sorry for my english

Ok, cotton is the best way i think. Just hard to find screwdriver for it's screw, so small.

I have the same probleme with my k850i. At the begining the screen get black ocasionaly but for a very short period of time, this hapenned rare in time. The condition became worst with time passing, first when i was presing the Down pad the screen get black for about 10 seconds. Then i installed the software again and again and the screen start to go black when i pressed all the directional pad's and the numeric ones,in the end the screen remains black but the phone is working i can call and dial numbers,enter.
I installed difrent kinds of soft versions but the result is the same, i replaced the keypads panel but with no result.I openned clean the contacts of the display but no result. I saw on the web that the display is to blaime is that true?
I read the topic but it end suddenly, did you manage to repair the phone? what was the probleme?
I want to buy a new display but i am not shure if this is the reale probleme.
