Coppell TV Repair offers you a set of replacement electrolytic capcitors most commonly failing on power supply board AEP016-37 / EEC-PWAEP01G000.
Those are some output filter capacitors around and between the heat seaks near the connectors for the inverters and the main board.
If you see any of them bulging the board will likely benefit from having them replaced.
Be advised, however, that electrolytic capacitors can often work even when bulged, much like a very worn tire can still be working until it blows; in other words, while bulged capacitors are a good indication of a problem they are not the guaranteed cause of a problem your TV may be experiencing.

This kit is a simple collection of the capacitors that tend to get bad most often on the board in one low-cost shipping and overall savings package.
