1084D monitor with 110v original label and 230v label added later?
« on: September 15, 2025, 02:00:39 AM »
I'm located in Canada and us 110v at 60Hz for power...

I have a 1084D monitor that I'm trying to use on my Amiga 500. When I plug it in and push the power button I can hear the button latch, but there is no power LED.

What is confusing me is that there is a home made "230v 75w" label stuck on the back, over the original label that says 110v. Looking at the internals of the monitor, I can see no obvious modifications.

I have no idea why someone would convert this monitor to 230v but I'd like to get it back to 110v.

I had someone tell me that there may simply be a jumper wire in the monitor that I need to add or remove, but they don't have the details.

What is the chance that this is really modded for 230v? Is there anything I can look for internally to tell if it's 110v or 230v? Does anyone know about this jumper wire and where it could be?

Would anyone happen to know the part number for T121 in an NTSC 110v 1084D monitor? In the PAL 220v it is listed as a "SMPS, TSW4210".
