Solo Signal issue on SoloSE V2

[GAP]

Dears,
I have VU+ Zero and recently purchased VU+ Solo SE V2.
I noted on Solo SE V2 tuner signal strength is lesser than the Zero's signal strength, on the same dish ant/ same transponder.
(11010V/32000/ 95.5E).

• On VU Zero sat meter: AGC 88%, stable tuned very easily : No pixilation on Channels
• On VU Solo SE V2 sat meter: AGC 99%, signal varies tuning is very difficult have to press ' tune button' several times to find the channels : heavy pixilation on channels

Please find the attached Sat finder images of both receivers for your reference,

Can you please advise me what causes the signal issue on Solo SE V2?
Could it be the Tuner or some capacitor issue on the Solo mother board?
Can I have the Solo SE schematics just to check the Voltages ?

TIA
