I need to replace couples of surface mount caps for the LCD monitor ,
but which type of surface mount capacitor should i choose? Low ESR or
general one, 105C or 85C?

Also, since I need only couple of them, where can i buy it cheaply?


Depends whereabouts in the circuit they are, and why they've failed in the
first place. In general, replace like for like, but most would agree that
upping the temperature rating is no bad thing. Low ESR types may offer no
advantage over standard types in areas such as general coupling and
decoupling, but may do in high frequency areas such as switch mode power
supplies, and backlight inverters. Most component suppliers will sell them
in 5's or 10's, but you may need to make the order up to avoid getting
hammered for twice the component value, in handling charges.
