All the capacitors will have location numbers printed on the bottom and top of the circuit board next to them like C18 etc--the values of each will be printed on each capacitor--as well as one side of each will have a strip with - which means it is the negative side of the cap and the other side will be the + or positive side--look for ones that are puffed up on top---see attached photo of a new and good cap--the silver top with the creases should be perfectly flat.
Any bad ones should be
visible to the naked eye.
Let me know what you find---if you find puffed up ones they will be marked also with a value like 1000 mfd (microfarad) at 10 v (means the cap is rated at 10 volts.)
If you find bad ones it is a good idea to replace with a higher voltage rated cap of the same value--it may present a small problem as the higher the voltage rating is the bigger the part will be.
The reason (if you have puffed up ones) they fail is because too low a voltage rated cap was used when the set was made---saves the company who makes the sets a few cents on each part.
Let me know if you have questions of need advice.

note the gray band on the left side--negative lead (each has 2 leads) is indicated that way.
