Radius pivot monitor focus / brightness-contract issue

[pcamen]

I have a color pivot monitor model 0356.  The focus appears to be off.  If I turn the brightness and contrast down, the focus seems to improve, but they are too dim.  If I turn one or both of them up (turning only one up doesn't make it quite bright enough) the focus gets way out. 

Anyone know of how the focus might be adjusted on this monitor? 

Could it be bad capacitors?

Well, I don't know much, but in general there's a focus adjustment somewhere inside the enclosure.

It's also possible that failing capacitors have thrown the focusing circuitry out of tolerance, causing the problem (adjusting the focus manually should improve it somewhat, but the caps really should be replaced if you want it to function long term).
