Hantarex Horizontal Image Size

[ggouweloos]

Hi,

I have an (old) Hantarex arcade monitor.
I'm not sure what type, on the chassis it sais "Hantarex d.s. 3".
On the chassis some potmeters are situated but horizontal size is missing. I found another post in the forum about a coil that could be ajusted with a screwdriver. The coil (I think) is near the high coltage transformer. I tried turning it but this does not seem to have any effect.

The monitor worked fine for a couple of weeks and started wiggling the horizontal size first, then it just blows up the horizontal size, so a couple of centimeters are fallen of the screen on the left and right.

Any suggestions how to fix this?

The coil is in the red circle.

There should be a paper label on the far right black metal bracket with your model number on it. I don't have any Hantarex manuals, but I think you have an MTC900/E model. It looks like your monitor needs a cap kit real bad as those caps look like originals.
