PACMAN Screen Curl and its NOT the monitor...is it?

[OriginalTHK]

Ok guys this is the . EVERYONE keeps telling me over and over ..."you need a cap kit" "what monitor you have" "adjust your monitor" blah blah blah

LOL

Heres the scoop....

I have an original pacman stand up aracde machine. when I first got the machine it worked ok but it had a screen curl just like this link....

I have replaced almost EVERYTHING in this machine.

Replaced

1. All wiring
2. Pacman PCB
3. Monitor
4. Fuses and fuse blocks

I think it could be the isolation transformers since its the only things I haven't replaced. Ideas? I am at a loss for ideas. 

Thanks

you can't post a link to a video that shows classic G07 curl. Take your own photo otherwise I am going to just say, do the G07 curl mod.

If you haven't already, remove the filter PCB that is between the harness and the game PCB. its worthless and only adds frustration. The isolation transformer shouldn't cause any issue like a curl. They pretty much work or don't.

If its a 4600, look on the darker XY board for a hidden adjuster hole.
Be careful not to break the ferrite core adjuster though.

thanks for the reply.


ian ....yes apologies about the video from someone else. but that is exactly what it looks like on my machine. I had pics but deleted them on my computer and then the board has to be sent off for repair...should be back by Saturday. so i couldnt take any new pics. plus the cabinet is at my friends house who lives 2 hrs away. rofl...long story but hey its just my life .


Thank you too Vertex. I am trying to get my buddy to take some pics. I should be by his house this weekend hopefully.
