Can the backlight be forced on with a jumper or not ?
First time seeing one set up like this with a backlight controlboard
mounted on the powersupply.

Re: lg 32le5300 no power/back light

I dont have a 3.5 v on back.light dim and a 3.5 both were
0 v. so wouldnt the power supply be the fault.

Re: lg 32le5300 no power/back light

When the back light is forced on..i have all the correct voltages
so i will try to find a controll board
