Default Samsung LNT4042H Capacitor replacement

Although I've done a lot of repair work before, I've never done capacitor replacement. I've got a picture of the capacitors I need to replace, but I have no clue how to select the correct kind, or from where I could/should purchase (the local RadioShack didnt seem to have the correct kind).

I can gather that I need a 10vdc capacitor with a 1000micro-f...but when shopping I was overwhelmed with the choices.

Trying to get this working for my grandmother. Any guidance is appreciated! Pictures below.

I have the same model TV, and did this repair in 2010. I ordered the replacements from DigiKey, part# 493-1497-ND. That DK part# is a Nichicon 10v 1000uf electrolytic cap. I forget how many it needs, I ordered 20 because I like to have extras for other projects. Clicking and power on/off issues were fixed after replacing the caps.
