Electrolytic capacitors can be very tricky in old hardware, yet, it is easy to replace them and give a kiss of life to our retro systems for the future.
After fixing the bad RAM on a ZX Spectrum 48K, I found out that the image is not great and understood it was a matter of power - unstable, at some part of the board.
Recapping can be followed in a number of steps, changing the capacitors stage-by-stage and this is what i can recommend.
The usual suspects you can start with are the C44 and C45 right next to the lower RAM section.
Useful information - like the list of capacitors for every model - can be found here below:
