Re: 32le5400 black screen

We need the pictures of the whole backside of the TV showing how all the boards are connected together, then the pictures of the whole top and bottom side of this power supply/LED driver board.
We always insist on having the pin name and follow by the Voltage reading for each pin so we can easily see what each pin are fore without going back and forth between looking at the pictures and the reported readings.
Your reports in post 1 does not even have the pin numbers.

I wrote down the voltages in the first post
Hope the image is clear enough

i have had a look for a schematic and cant seem too find one, if there is any writing by the connectors you have measured these voltages can you add the information to the voltages you have provided, that way we can see what each pin is supposed to be voltage wise etc.

Hello all,

I got a Lg 32le5400 tv here with no picture on the screen.
I could not find any picture with a flashlight.
I opened the tv did not see anyting strange.
I opened the lcd panel i found some leds are on but very low brightness. (In the middle of the strip).

It has power supply 3pagc10017a-r.
I measured the voltage on the connecter from the power supply that run to the strips and get these results:

Are these voltages ok? Or is there someting odd because when i google i founs on a website that it should be 24 volts.

With kind regards
