i have a question. when the display fades off, does the unit still functions? i mean do you still able to make a call or receive text messages or the keypad lights still illuminates even the display fades off?
If the answer is yes, then the new lcd that you have just replaced recently is defective. have it replaced again but now to a different source. maybe the lcd that you replaced is not a good quality.
if the answers is no. have your unit reprogram, it has a corrupted software.
Hope I helped you in your problem... Don't forget to rate me OK! thanks...
Most likely there is a problem with the keypad connector at the controller board. Usually these have a sliding collar that locks the keypad's flat flexible circuit material cable in place. Pull it up about 1 - 2 millimeters on both ends until it hits the stops (it doesn't take a lot of force, and it may even be loose already given what you describe). The cable should then pull out easily. Polish the contact stripes on the cable end with a white pencil eraser (the kind found on mechanical pencils), then wipe clean with a piece of tissue paper or clean dry cloth. Insert the cable back in the connector, and push the collar down so it is locked at both ends.
This is the most probable fix. It is possible that the connector is the problem; electrical contact cleaner may help. Other possible causes are a broken key-scan line* in the keypad, micro-controller chip failure, or a bad connection on the circuit board in the affected scan line.
*The keypad is wired schematically (if not physically) in rows and columns. The micro-controller activates a line in one direction, then scans all of the lines in the other direction to see which key if any has been pressed. 0,1 and 2 are on one of these lines, probably with several non-numeric keys; the remaining numbers are on another line (or two).
remove the back cover .. then remove the front cover. it will bw really tight check for the points from where it is inserted into the body.. whn u get the front coer out. take out the key pad and replace it
Hi, the actual circuit that is open is the cancel key connection. Here is a check list that will help. I would consider replacing the ERC if the control is integrated.
1. Check keypad connector for firm connection (keypad connects to control
2. Press CANCEL. If error code returns after 60 seconds, replace keypad
(also called touch pad or membrane switch). Some models incorporate keypad
in to control board as one unit. In this case, replace control board (also
called ERC or clock).
