@tiagocorreia it is easily possible that this is not one capacitor but that you may have to recap the TV. After all, it is now what something like 25yeas old :-) Post some good pictures of the boards with your Question. That way we can see what you see and maybe we even find some oddities. [guide|21499]
Once you recapped your boards, you may have to do some adjustment on the Flyback transformer etc. For that use the [document|41814] service manual. Please remember that this is a CRT that can generate some pretty high voltages. Those do pack a punch if you get zapped on it. Make sure that you discharge the CRT before working on it etc.
