Hello evryone i am new to bb and for start i bought 7290 for some small amount of mony i ther is no back light how to start a back light and how to connect a bb to pc can anyone help me

There likely isn't anything that you can do to restore the backlight if it is inoperable now.

The device connects to the PC via a standard and relatively inexpensive USB cable.

thanks man and i haw one more question i have some old bb7230 with broken display does anybody know how get sper one and how much does it cost

the back light botton is the lowest botton at the bottom right hand corner of your phone.I guest you know that by now.i dont know about the pc connection because mine is not connecting either

try ebay. you can get used phones for parts verry cheap
