Right, well here goes with my thoughts:

CDA Panel. Swap the valves out - you never know. If this doesn't cure it, don't muck about - Swap VT29, VT30, VT31. There's 3 electrolytic caps - Two go to deck and the third one links Green to the other two. Again, swap all three.

Decoder Panel : This from Mikey's site...

'Extremely bad hanover blinds with incorrect colours (Yellow jaundice flesh tones): (D/S and S/S) This is caused by the PAL bistable not reversing the phase of the R-Y signal on alternate lines. Check D26, D27, VT22, VT23 on the PAL decoder board.'

Does this help.

Cheers,

Steve P
