The problem is usually cuase by a broken microswtich which is located between the battery slot and the SD card slot and it is activated by a tab in the battery cover.
If you feel technically inclined you can open the camera carefully and take it apart to the point where you can remove the upper circuit board ( NOTE 1: make a careful note of every screw you remove since they are different size and need to be used exactly in the same order) and then the small black plastic assembly above the circuit board below, you can see the defective switch on top of the 2nd board, remove the plastic part of the switch until you see the bare 2 contacts on the circuit board, solder a small piece of wire to bridge the contacts, now very carefully reassemble the camera observing the exact order of screws used, see NOTE 1. If everything is back in order insert the battery and the camera should work now. 
note: should you not be inclined to do this work and want to sell the camera as is for spare parts I am interested, drop me a note at: cocnutray at yahoo.com. A Nikon repair shop will charge between $80 to $110 FOR THIS TYPE OF REPAIR, THEY WILL ACTUALLY REPLACE THE DEFECTIVE MICRO-SWITCH. HOPE THIS HELPS :-)

I woold like to use a 8GB for my coolpix P4. May you sugest me if it is possible and which brand ?


Unfortunately, you can't. The P4 only works with SD cards, and SD cards max out at 2GB in size. This is a hardware issue and cannot be changed by a firmware update.

MY LCD screen is broken. What do you suggest me to do?


Given that the P4 was introduced four years ago in a market that designs with a two-year (or shorter) product cycle, repairing it is almost certainly going to cost you more than replacing it. If it was me, I'd replace it with something more modern.

I bought the Nikon Coolpix about two years ago. Suddenly all the pictures taken are overexposed. What do I do?


Two things to check...ISO (should be auto ISO or a setting between 100-400) and Exposure Compensation (should be set to "0")

Nikon Coolpix P4--Won't turn on!


No lights or anything?

Best I could offer at this point is check the battery contacts are clean, use a pencil eraser or a cotton bud (Qtip) moistened (not wet) with isopropyl alcohol (tape/stylus cleaning fluid) and check the battery door is properly closed...
