You’d best check all satellites on tuner A and then switch the two cables and check all four satellites. If this works on both cables then the DISEqC + cables are ok.
Then you check the four satellites on tuner A (deactivate tuner 
and afterwards check the same on tuner B (disable tuner A) Depending the results you might rule out a defective tuner.
In this way you might find the cause.
Mijn schotel is een T90 met 10 LNB's. Daarnaast voor de fun nog een draaibaar systeem met een Triax TD 78.
Dreamboxen heb ik niet meer echt actief. Verder heb ik ook nog een een VU+ duo2 met 500Gb harddisk + een VU+ Uno, Zero, Solo 4K, Ultimo 4K, Zero 4K, Uno 4Kse. + ook nog een Xtrend ET7x00. Daarnaast heb ik ook nog diverse andere modellen w.o. een Formuler F4, ET8500, ET7500, Mut@nt 2400HD, Xsarius Fusion HD se en verder nog wel het e.e.a. waarmee op verzoek vanalles wordt getest. Iemand moet het tenslotte doen. 
Los van de eerder genoemde modellen heb ik nog wel een rits aan testsamples als Mut@nt 2400HD, HD60, GB UE4K, GB Trio4K, Maxitec Multibox combo en Twin, Octagon sf8008, sf8008 mini en last but nog least enkele modellen van het Grieks Duitse Edision.
Voor centrale opslag van media gebruik ik een Qnap 219P met tweemaal 2 Tb harddisks + een Synology DS414 met 12 Tb Totale opslag.

Dear
I have similar problem
4 Quad LNB's connected to 3 DISEqC with 3 cables A, B and C
Cables A and B connected to Vu+ Duo2 tuners A and B
Cable C is conected to Edison Receiver. Say Tuner C
For many years while any tuner is in use or recording , the two other tuners work properly i could browse and record , some times multiple recording on two tuners, still all channels on the third tuner are working properly.
For the last year
When one tuner is in use the other two tuners do not work properly many channels on all LNBs becomes week or fail to tune or signal disappears regardless of the polarity or high , medium low frequencies, Few channels on all LNBs still working.
I have tested each tuner alone works perfectly with the other 2 tuners off or disconnected, which indicate that tuner, cable, DISEqC amd LNB's are fine.
Tested tuner A equal to tuner b , still same problem.
some times when say tuner a is ni use recording tuner B lags alot for tunining.
Any clues.

Further more
I am suspecting the DISEqC's or the cables, considering to change for new.
