Question about Elo 15" Touch Monitor
I got a ELO 1524L LCD touch monitor. The back light doesn't come one anymore. I found the backlight is still good. I tested it with another lcd monitor and the backlight comes one. I'm not sure if it's the power source going to the inverter or if it's the inverter itselft that's bad. I do get voltage readings going to the inverter. There are six wires. Two wires get 15v and the rest don't have anything or like .8v. Can't find the inverter for this model. Is there a way to use another inverter since these backlights are able to power up with different inverters?
You should have 2 wires for 12~15 power going in, which you already indentified, 2 more wires should be for ground return, you can check for them by using Ohm meter between the chassis and probe the wire for less then one Ohm resistance. The other two wires, 1 wire will be for Dimming control (usually 0 = dimmed, 5vdc = full brightness), 1 wire will be for BACKLIGHT ON/OFF (0v= OFF, 4~5VDC = ON) control.
Dose the fuse on the inverter board check out OK? You can use other inveter board as long as the lamp connectors are the same and you just have to match the input signal pin. I have done many.
See example of the fuse on the inverter board.
