The easiest way would be to download the service manual, but you can access the service menu by simultaneously pressing [ENTER} and [DEGAUSS]

Re: PVM20M4E Sony monitor geometry adjustment
Started off by replacing caps known to cause issues on this model (see pics)
Also discovered a 4.7MF,160V behind LOPTX with high ESR
Set up geometry best I could, after customers fiddling.
Enter service mode by first pressing MENU button, then DEGAUSE & ENTER together.
Once in service mode use MENU & ENTER to move through different adjustments.
Arrows up & down to alter values.
DEGAUSE to store. Might need to press it twice.
Waiting for the retrophile to turn up with his Nintendo WI for the final verdict.
