Sanyo 14" monitor hula

[inspector]

The 14” Sanyo monitor has waves (hula) ~~~ going across the top and bottom of the screen (vertical mount), if it was horizontal, the sides would be doing the hula.  I have recapped the monitor, changed the flyback, replaced IC601, replaced the width coil and checked for burnt parts and traces: none. I cannot figure it out, I have spent countless hours trying to. Any help would be appreciated.

maybe the ground is bad or more likely your transformer is too close to the yoke,what about the flo tube

[inspector]

I moved the transformer 3 feet away, it is not that. I also switched transformers, same problem. The Sanyo monitor is the only one that has this problem, I connect all of my monitors on my work bench. I also have the frame grounded, no problems. Can you give me a little more info on the flo tube?

I am no expert , but my suggestion would be that you should change your power supply.I also had this type of problem and it was caused by power supply.

[inspector]

The transformer is the power supply to the monitor, which I said had been changed. If you mean the game power supply, I already had changed that also.
Thanks for the input.

I am talking about the arcade power supply which has +5v,+12v and -5v.

[inspector]

That is the game power supply(+5v,+12v,-5v) which I said had been replaced.
Replaced:
transformer,
game power supply,
flyback,
IC601,
width coil,
and installed all new caps.

I have connected multiple pcbs, same problem.
It is in the monitor, I am looking for someone who knows about the sanyo units.
