Doc, yes it all is connected properly. You did not tell us if you have power on the LCD driver and if the power LED (on the menu bar)comes on. You need a minimum of 12 Volt on that. Also, you hopefully ensured with the person you bought the inverter/LCD driver board from, that it works for your panel. They have to be very specifically wired for your LCD. Just to verify, you should also tell us how you connect the LCD driver board to the PC, and what type of PC you are using. You must use a VGA cable to connect from your computers video card to the LCD driver board

how do you power your backlight for you lcd ? Because i'm working on a Modification, and so far, i've found that you'll need to bring 24v to the backlight (wich seems connected to your old mac PSU), but if i'm correct, the 24v is powered only after Power On ;)...

Or maybe your board arrived with an AC adaptater wich does at the same time 24 / 12 V ?

That voltage is usually supplied by a boost converter and the LED driver on those boards.

I have the same problem, does not fit the light lcd, even connecting it to the PSU Mac .

Sure there something I'm not doing well, but is not it ...

See https://pbase.com/brucemac/2019octdispla... for my successful conversion from a 24” iMac (Early 2009) to a monitor. The inverter board is built into this display, but you’ll need 24Vdc to drive it - Thus, you’ll need a power supply. (unless you can figure out how to make the original PSU work…)

I'd very like to know where did you manage to find your 24Vdc PSU unit ? can't find one of those.. i've all the board and things ready in a box for years now !

I found mine on ebay. Search for "5V/12V/24V Universal LCD/LED Power Supply Power Board for LCD " on your favorite search engine, and you'll find plenty.

I bought the light colored one, as you see, though there are several that are dark/black.

This is the one I purchased:
