Hi again from Montreal to all fellow techs !!

This is my third posting about this problem. (last one was 6 months
ago).
Most monitors will power on normally with only 110VAC.
This one refuses to power on unless I apply 122VAC. (I use a variac to
boost the input voltage a little).
I checked all power supply caps with an ESR meter.(no problems)Thanks
again to Bob Parker and his famous ESR meter.
I also checked all power supply resistors for correct values. (no
problems)
All diodes and transistors seem OK around the power supply.
I have the schematic and service manual.

Is there something else I should check ??

Many thanks,

Jacques Carrier
