Why is that

yes of course, you need a new battery.
when you get this battery, also buy a universal charger.
do not insert the battery into the phone until you charge it for 3 hours with the universal charger.



after that the phone will work very fine.

there may be two reason for the following cause-
1.your battery may be drained up
2.or their may be any virus.
in cause of battery you have to buy new one but in cause of virus you have to format the phone by following method.
To format the (restore factory settings) phone here is a way .
1. Make sure you phone is fully charged. (At minimum 3/4 of bettery should be left)
2. Backup your contacts list and personal files to MMC memory card (if possible).
3. Switch-off your n 72phone.
4. Press and hold these three keys together
-Green dial key,-Star key (*)-Three key (3) then press the power on/off to swtich on the n72phone.
Do not let go the three keys until you see the formatting screen displayed
5. After a few minutes, the format will be complete. Your n72 will now be at its original factory settings (It will reach the same state as that in when you purchased it). All inbuilt applications provided by nokia will not be deleted).
i recomend you to format first.

i think u have to change u r lcd and u have to spark the battery first if u r battery is nill

there could be 2 reasons.......first the fan might not be working and you need to buy a new one or fix what you allready have.
second it might bew dirty from the back take a swiper an clean it for 30 sec one of those will work 100%

Yeah dont buy LCD over hyped ****!! I buy only plasma's better blacks & better picture! Try the Panasonic THX plasma & read the reviews on it! I own 2 plasma one new & one 5 yrs old! Also own one Sony LCD...LOL..it's in the kids room! Even Sony's best XBR $5000 plus 50" tv does not compare to a Panny THX!
