    1st go to the customer convergence menu and try to adjust red. Does it move at each of the points in both directions? If not (this is what i suspect you will see), forget about the service menu it will not move there either. Your problem is a circuit failure. Look around this web site and you will find a 1000 different posts about your problem. It will consist of a couple of amplifier IC's and maybe a few resistors. Then your adjustment should be minor and you can probably achieve it with the customer convergence. If the red moves fine in the customer menu then post again and i'll try to hel[p you through the service menu.
