Question about LG Televison & Video

Have a Lg tv when I plug it in I hear a clicking noise from the main board and the power light blinks. I can press the reset button and the clicking will stop but tv still won’t come on. Is the main board bad?

Charles Hughes Nov 26, 2020

If I hold the reset down the tv comes on but when I let it go it turns off and the power light stops flashing but will only turn on when you hold down the reset

LED TV's have a known problem with capacitors going bad. Without the proper capacitor test all you can do is look for a cracked swollen possible disformed or any burn marks around them to find the bad one to replace best of luck you'll find it

Depending on the model maybe. Tv's like all electronic items use multiple circuits that are interconnected. So if you have a problem like you described it can be any interconnected board. I experienced problems like you described many times. Use your eyes and nose. Turn off the power, remove all boards and visually inspect. While boards are out sniff each board. Look on both sides of each board. If nothing is found I would start with the power supply and replace it. You can check the output voltage where the power supply connects the the main board. It is harder to check the main board function because the signals pulsing thru the main board require specialized equipment.

SOURCE: My Reset button wont reset

Just guessing, here. The reset is actually a "Ground Fault Interrupter" called a GFI. It's there to cut of power in case of a dangerous electrical condition--which you probably don't have.

Did you unplug the unit? If not do so, let the GFI cool for several minutes, and try to reset again. They're pretty hard to push in, maybe use a fingernail, you must hear a click or it's not reset.

Is there water in the outdoor unit, or is it filled with snow? This is the most likely cause of an actual GFI fault.

If the GFI itself has failed (unlikely), you could replace the entire power cord. You should then maintain safety by installing a GFI circuit breaker on that circuit, or you'll be in violation of codes that might affect your homeowners insurance.

There could actually be a problem with the unit. This would be that an electrical wire has come loose and is contacting the metal chassis, creating a shock hazard. Unlikely but possible.

If the receptacal you're plugging into is old and worn it might the problem. Worn receptacles might actually have tiny electrical arcs inside, which can trip a GFI. At a couple of bucks (DIY) it's worth a shot.

If there's actually an electrical fault in the unit it can be found and repaired, but the cost of repair could very well be more than it's worth. Warranty?

My LG 42PQ3000 is making a clicking noise from the large PCB when power is turned on, there is no picture and the stand by light is going on and off

Standby light goin On/Off, means the power supply regulator board is OK. Blinking of the standby light indicates a fault. It might be to the backlight inverter board, or the main board. These blinks of standby light are called blinking codes, from the number of blinks occur at one time switch ON, you can get an idea about the faulty board inside the TV. Count this blinks. If you wish to get more details about these blinking codes, check the site linked here.http://electronicshelponline.blogspot.com/

My tv won't turn on anymore. The power light and the opc light blink twice at the same time and then the opc blinks once and it keeps doing that. Please help!

Hi

Make sure the AC cord is not loose or disconnected. Check to ensure the cord is firmly plugged into the outlet at one end, and firmly connected to your television at the other end. The AC cord connects to the television about midway across the back of the set, near the bottom of the back panel. The hole for the AC connection is shaped like a figure eight. Try powering up the TV with the cords firmly connected.

Check the "Main Power" to ensure it is on. Locate the button on the top of the television among the "Volume" and "Channel" buttons. Press the button to switch the television on. If the "Main Power" button is off the remote will not turn on the television. Wait to see if pressing "Main Power" will activate the TV.

Press "TV Power" on the remote control to power up the TV from stand-by mode. If the power light on the front of the television glows red when you press "TV Power" on the remote, press the "Main Power" button on top of the television to remove the TV from stand-by. If the TV is accidentally in stand-by mode it may not come on when pressing certain buttons.

Check the circuit board. If your set still won't turn on and you hear a clicking noise when you plug it in, you most likely have a defective circuit board.

Aquos LC37D40U Blinking light and won't turn on

The power light is an error code that tells me exactly what is wrong with the TV. Count how many times the POWER led flashes per second? (Dont worry about the OPC led)

1x per second (constant steady blink) = bad inverters/lamps
2x per second = bad power supply
3x per second = bad main board

If its 1x per second, try doing the factory initialization to get the TV back on to confirm a bad lamp/inverter.

Try doing the Factory Initialization (WARNING: THIS GIVES YOU ACCESS TO THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)

unplug tv
press and hold at the same time “Vol –“ and “input” button on the TV set.
while holding those buttons, plug the tv back in
the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go.

Once the TV turns on, take a look at the screen. Does it flicker then shut off? Or do you hear a buzzing noise from the right edge of the TV? If so, then you have bad inverters or lamps. Once youre done, unplug the tv to get it out of the service menu.

If it is 2x per second or 3x per second, then those boards are just bad and they need to be replaced. There isnt anything you can do right now to fix it.
