Power supply failure if mains power is OK

LG Televison &... | Answered on Sep 06, 2019


The click sound is the power relay coming on and off. The tv is sensing a power problem and shutting itself off. If you are handy, remove the back of set , disconnect the connectors to each board and check voltages out of the power supply. If they are not to speck, replace power supply board. If they are ok, reconnect one board at a time and see if power stays on. You should be able to find the bad board this way. Visually inspect each board for burned components or swollen capacitors.

Your backlight inverter board is likely bad. If you're handy it is relatively easy to replace. Google for replacement part.
if you can see a picture while shining a flashlight on the screen then it is most likely the inverter board. Backlights provide the light through the lcd screen for brightness.

Hi Larry, for what you say, you have badly the Main Board or the LCD Panel, you can try disconnecting one of the connections between the T-Con Board and the LCD Panel and see if you see a half-screen image, try disconnecting one at a time , if half of the image appears in any of the image, the problem is in the LCD Panel, if nothing appears, then you would have badly the Main Board
I hope you can solve the problem

Hola Larry, por lo que comentas, tienes mal la Placa Principal o el Panel LCD, puedes probar desconectar una de las conexiones entre la Placa T-Con y el Panel LCD y ver si te aparece imagen de mitad pantalla, prueba desconectando una por vez, si te aparece en alguna la mitad de la imagen el problema esta en el Panel LCD, si no te aparece nada,entonces tendrias mal la Placa Principal
Espero puedas resolver el problema
Saludos Franco Dosil

Hi Troy, when you say blank screen, it's an illuminated screen or you just want to say a screen without a dark image
If it is the latter, it is very feasible that the fault is in the LEDs, try turning on the TV in a dark room and with the help of a flashlight, illuminate the panel on the inside and back, to see if there is an image
If the case is a screen that looks white, the lighting would be fine and the problem could be on the Main Board

Hola Troy, cuando dices pantalla en blanco, es una pantalla iluminada o simplemente quieres decir una pantalla sin imagen oscura
Si es lo segundo, es muy factible que la falla se encuentra en los LED, prueba prender el TV en una habitacion oscura y con la ayuda de una linterna, iluminar el panel en la parte interior y posterior, para ver si hay imagen
Si el caso es una pantalla que se ve blanca, la iluminacion estaria bien y el problema podria estar en la Placa Principal
Comenta

Sorry we do not sell parts nor do we have locator services other than a Google search engine.

Open internal fuse or power supply failure

LG Televison &... | Answered on Aug 21, 2019


if all you got when you did the auto setup was 18 channels, that is because that's all the channels that your tuner could pick up in your area. There is no additional settings you can make or changes that will give you additional programs without an improved antenna system. Without knowing what kind of antenna you have there's no way to suggest an improvement.

You should have manual buttons on the tv itself to control input and volume. It appears it is defaulting to antenna channel 3 and low volume when first powered on. You can buy universal remotes to control your set.
