While the screen goes blank, does it drop the call? Are the handsets fully charged, or are they on the charging dock whenever they are not in use?
The batteries may need to be replaced. Bad batteries can in some cases cause the phone features to not fully work. They are located in the back, bottom of the handset.
If you have a screen protector - remove it. The phone thinks the screen protector is your ear pressed against the phone and will not display the dial pad.

Your display circuit is broken, even if the LCD-panel,
seems to be ok the display is damaged.
This is a very common problem in Nokia phones.
The only way to fix this is to change the display.
You need a T-5 or 6 Torx Skrewdriver to do the job.
You can find displays for fair price at :

If it's the SGH-D900i phone that you have... Go to Menu... Settings.... Phone settings... Slide Settings... in there you have to change the "Down" from 'Continue operation' to 'stop operation'... save and slide the phone shut, that should once again lock the keypad.
This type of problem occures in mobile phone due to followig reason...1..Defective software 2...Defective Key pad IC 3...Defective CPU IC.
First is cheaper and will be solved by any skilled technician.
2nd is Hardware problem and also can be repaired by techincian.
3rd is very werst thing. I pray it might be with your phone.
Key-pad scanning is overall duty of CPU IC of the phone. I advise you to contact nearby technician and ask him to put it right by software. He himself reply you what to do? Yes, this is paid service and he will charge you little. If u find it fixing your problem then do vote here.
