RCA Entertainment Series Console TV

[Console User]

I have the Model G27647 RCA Console TV Entertainment Series with the CTC203AX Chassis. I go into the Service Menu to Adjust the Color Drives and it's not storing my settings. Instead, it is changing the settings to random numbers neither factory set or numbers changed by me. I hit the Menu button then power button before turning the set off. However, it is not storing the settings I want it to be set on.

Anyone have any advice on what's going on here?

Thanks.
