well for ur problem
go for a new panel w/ keypad which costs bout 90 rupees,
paing 150 rupees at a nearby shop is fine

secondly the led's can be changed ,
a experienced repair person can do it,
i like ages ago had completely changed the led's ;
and backlight led's to BLUE on my 3310 and installed,
a transparent panel making it look UBER cool.
tho it must be seen that when i did it 3310 was
a GOOD phone. now it's just obsolete.
so go ahead find the right guy (NOKIA CARE WONT DO ****),
and mod ur phone.
aloha
