Popeye issues

[AlexK]

Hi,

After Years of error-free operation my Popeye picture is upside down....can somebody give a hint whats the issue is ?

Thanks in advance

Assuming this is a Nintendo upright cab with an original PCB and sanyo EZ monitor?

If dipswitch P is off it's in cocktail mode and might flip the screen. Flip it to on.

Start a 2 player game and kill the first man. If the screen flips the correct way up for player 2 then you've got it in cocktail mode.

I have an Upright Cabinet and haven`t changed the DipSwitches. As said i have it here for years and it had worked perfect. It must be a PCB Problem.

I'd still check the dip switch to rule it out but whatever you think...

According to the Popeye schematics Dipswitch 2 which controls game settings plus cocktail/upright modes is connected to LS151 @5N before outputting to the AY-3-8910 may be worth checking the LS151 is not faulty

Check the DIP switches as well (continuity test). You can't be sure they're still making contact after all these years.
