Amiga CD32 color problem can anyone help?

[Duffsta]

Hi guys I just turned on my cd32 after a year or so yesterday and it's only displaying Green and Blue.
Today I've turned it back on and it sometimes loses Blue after 5 secs and only displays Green the capacitors have never been changed I brought it off someone in 2007.
This problem seems to happen in Composite and S-video and RF, i'll post a picture below any help or recommendations would be great?.

Watch this video, maybe it will help You:

however, as one colour is missing it seems like a cable fault or capacitor issue.. There are more parts of that video just watch all parts of them, and You'll find out a lot of interesting things about

Capacitor leakage on the board i expect , Sony decoder fault ...the list goes on.

A cap change is first on the list i suggest.

try another video output if you can (S vid , composite , Tv )
