LG CRT Repair and servce menu.

[dark666]

Hi to all.
I'm repairing an LG 32'' CRT TV model RE-32FZ30RQ.
The TV didn't powered on. I resoldered the PSU area and its back on.
Had horizontal stripes across the screen and it was flickering making huge noises from the tube.
Resoldered the flyback and adjusted the Focus 1, Focus 2 and Screen of the VRs on the flyback transformer. It stopped flickering and the lines went away.

Now it flickers like once every 30 min.
Could it be that the Flyback is dying?

I would like to enter the service menu to adjust the geometry of the TV but I can't seem to find the service menu.
I searched the internet and found several forums that state that holding the OK button of the TV, and the OK on the remote together for 5 sec it should enter the menu. On this TV it doesn't, it just starts scrolling the TV several functions like in Demo mode or Self-Test mode, but no service menu.

How do I do it for the Service Menu?

Thanks.
