Help please :(
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
You need an inverter mate
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…) Update (12/01/2020) I’ve added a diagram of the boards & cable routing to the display: https://pbase.com/image/171252938 Help that hopes!!
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 ?
Hi, You can use iMac’s PSU to power LCD board controler (see here) but you have to add a bistable relay to enable imac’s PSU (see here)
Schema Bye,
