AppleVision/ColorSync 750 Display standby light color

[Dennis Nedry]

I have this AppleVision 750 Display that is acts a little strange. It won't always turn on, sometimes it will turn on for just a second and turn back off, other times it's fine. It may have the classic cracked solder joints on the flyback transformer thing going on. I still have to take it apart and check on that.

Something I noticed though, is that the power light is always either green if it's on and black if it's in standby. Can anybody verify if this is proper behavior? Usually a monitor's power light would turn orange in standby.

If somebody has an AppleVision/ColorSync 750 or 750AV, if you could just plug it in and see if the light turns orange I would appreciate it.

Your power LED is operating properly, no 1710 or 750 display power LED should ever turn amber.

I have this AppleVision 750 Display.... It may have the classic cracked solder joints on the flyback transformer ....

My 17" ColorSync, which is otherwise pristine, sadly has terminal video problems (meaning it is presently a boat anchor): it started to go out of focus for some months, then the screen partly disappeared, then it would black out, then it got put away for a year and has been awaiting disposal or repair (I can't bear to throw it out). I might give fixing it a go if it were not so dangerous in there.

Is retouching the solder around there a difficult thing to do?

Thanks for the info on the LED. This is good to know.

Retouching solder is easy if you have the right tools.

This is all you have to do:

Use a high-heat iron to melt the solder you want to fix. Use a solder vacuum tool or some other tool to remove the solder. Reapply new solder.

You do have to remove the old solder because the crack may easily reform if you just melt it and then leave it there. Carbon may have built up in the crack and simply heating it up won't remove that.
