32le5400 black screen
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:
From top down
On p204
88
0
10.5
10
10.5
0
0
10.3
10.5
10.1...Last edited by xorium; 12-24-2017, 09:41 AM. -
