I have never seen inside a Sat 2000 before, but in your photo of the VHF tuner, I can see the top of what looks like a black rectangular ceramic capacitor.
Most likely 0.1 uF. I met hundreds of those inside the CUC series of colour TVs in both the Tuner-IFs and on the tuning boards. They adsorb moisture and become leaky. If they are on a power rail, no problem, but if on some high resistance area, expect trouble. If you check on an Avo 8 high resistance range, they usually show up, but the other two ranges show them as OK. I used to replace with a red Wima, but later Grundig started to fit identical ones, but dipped in a blue coating. They were all OK.
Never known a dodgy varicap diode, but I guess nothing is immune to failure.
