Factory service code for VU pixelight HDR 2019 model

[ksarvind123]

nearly a month ago I have bought a new VU pixelight HDR 43 inch 4k TV but colour purity is not accurate therefore I tried calibrate it. It has color tuner option in it's menu but it doesn't work. I could only adjusted white level but when I view reguler pictures then it shows a unnatural redness in picture and that can't be removed. If anybody can tell me the service menu codes

Searching on google.com I have realised that Vu TV is rebranding Chinese Hisense TV. The mother board is being used buy other TV brand in India also like BPL loyed Akai etc.
I also found the answer of my question.
