  • Display problem with my xxxx in 1

    Hi,this is my first post on the forum and i have recently purchased my first arcade machine being that of a Lowboy.

    I had a Radian Fighter jamma board in the machine but have recently replaced it with a xxxx in 1 redbox purchased from game dude.
    The problem i am having is that the screen is split in two down the middle and no matter what i do with the adjustments which i think everybody calls pots?

    I have also jumpered the common to the video ground this gives a clearer picture and thats it.

    All the buttons are working fine and i can select games and play them.

    Could this be a resolution problem?

    Is there any horizontal hold options on the monitor or board?

        That first pot on the left H posi should be the one to adjust.
        If it isn't broke then don't fix it!

              Interesting point where would they most likely be located?

                Not sure about the Gamebox but the 1066in1 box I have has a button to switch video modes, it cicles through PAL\NTSC\VGA, check that and make sure you are outputing either NTSC or PAL (depending on the screen)

                  Ok i have looked on the back of the tube and i can see what looks like a red,black and green like dial that has a flat screwdriver like groove on the side are these pots?I have attached a photo that isn't the best quality but the dials i am talking about are on the bottom right of the picture .

                  With the video modes i pressed the S4 button on the xxxx in 1 box before the windows screen came up and got the screen that i have attached in the photo most of it is written in a different language but i can make out the letters VGA that are situated half way down the list.
                  I can not scroll through this list no matter what buttons i push on both the arcade machine and the xxxx in 1 box.

                    I wouldn't touch those adjustments, they will just adjust the level of the Red\Green\Blue. They won't help with your issue.

                    That is just the Windows OS boot Option (Safe Mode, VGA Mode, etc)

                    You will need to wait till it's in the menu then try the buttons for video mode, it has to be in windows so the software that sets video mode is loaded.

                    Cheers,
                    Beau

                      Ok then i have tried pressing all the buttons on the gamebox and cant seem to get any lists up that resemble video modes.Should i be pressing the buttons between when the windows screen comes up and before you can see the games listing screen,as i have been doing this and it dosen't seem to do anything.I can however change settings for each game that is loaded up but im guessing that this isn't the screen you are talking about in regards to changing video modes.

                        Try the H-hold one

                          I think its more likely your jamma wiring than your screen. I reckon you have a grounding problem somewhere...

                            I have tried adjusting the H-Hold pot and it won't get rid of the split screen and
                            when i plug the original Raiden Fighter PCB back into the machine the screen is fine so would this still mean that it could be a jamma wiring problem?

                              if its a redbox ive heard that have issues

                              this could be one of them. have you checked the chassis earth pin is the same as the jamma one?

                              could be the earth isnt properly being grounded from the rgb signal off the board
                              you can always expect change in life..except from vending machines
