LG 32LN5100 power problem
« on: September 20, 2021,16:55:41 »
Hi
I have a LED TV
Model : LG 32LN5100
there is a problem with power board (Model : EAX64905001)
after testing the board I figured that the Chopper circuit is dead , so I tried to replace it with these options :
Viper12A
5L0380R
DS0088 Module
all three methods managed to give standby light (with all voltages) still when trying to turn on , TV light (backlight LED) blink and return to standby .
I checked CAPS , Diodes , Resistors ... all seems to be good .
I've noticed that there is some voltage drop when turn on .
Voltages :
3.3V
11.8V
24.5V
Am I missing something ?
thanks in advanced .
