[ICOM] IC-756 PROIII Screen Flicker

[Dick Flanagan]

Try disconnecting all external connections (ground, antenna, 
microphone), try different power supply, plug into different power 
circuit, to see if the flicker goes away.  If it does, then start 
adding things back one at a time to see which one causes the flicker 
to return and then go from there.

If the flicker is there with the radio isolated as much as you can, 
then move the radio to a different room/floor/house just long enough 
to verify if the flicker is still there.  Make sure there isn't a big 
amp power supply sitting right next to the radio or other 
emi-inducing appliances on the same electrical circuit.

By systematically isolating things within the radio's environment, 
you should be able to track down the cause.

Please keep us advised of your progress.

73, Dick
