How to increase Brightness on My MVS 6slot machine HElp please

Just wanting to know how to increase the brightness on my monitor for my MVS 6 slot , also the screen seems to be a little off center aswell want to know how to fix that too.

Is it an L&A cab like mine, if so it may have a Kortek monitor, there will be a sub PCB with hor shift, hold, bright etc- have you adjusted these pots.

Also there is an adjustment just below the focus on the lfbt. Thats the screen voltage adjustment pot, if set too low you get low brightness and maybe flairing on peak whites or RGBs.
Too high and you will be able to see retrace lines.
It should be adjusted in low ambient light conditions so that the phosphors just about illuminate on black level, then back off slightly.
WARNING- Very high voltages around the lfbt stage.

yeah my machine are the same as yours same look every thing where abouts is this pcb could you take a photo for me and show us i'll give you my email to send the pic too if you can help me out

Looking at the monitor PCB topside with the flyback transformer/ output transistor aluminium heatsink top RHS, the socket for the sub board wiring is bottom RHS, follow these wires. The sub board will be screwed to the rear inside of the cab.
I forget exactly where, mine are loose as I mess around with other boards and am forever adjusting the pots.

BTW welcome to the forum Sazabix, only said this the other day to another Australian member with a L&A aussie cab. Good to see

Thanks Heaps guys i figured it out yeah i love my new neogeo machine

enjoy
