Most of the caps are at where the power plug comes in. There are a few tiny can caps on the rest of the board. You should wash the board to eliminate the leaked cap goo. I use a 3 parts water/2 parts ammonia bath. It it dried with hot air from my heat gun; you can use a hand hair drier set on high and hot. I then scrub areas around the caps with acetone and a tooth brush and lightly rinse with acetone. Followed by a high proof isopropyl alcohol heavy rinse. Then blow dry with the hot air. This is for the logic board, not the LCD Panel.

Remove/replace the caps one at a time while using a q-tip and acetone to clean the board under the cap. Check electrical connections with a multimeter. At the same time check for rotted traced and fix before putting in the new cap.

I did a clean up and recap of a 230 sometime last year, it is easy, just take your time doing it. And double check your work.
