Samsung tv MODEL UN40F6300AFXZA


Please un-plug the cable between the main board & the power supply board, apply AC power to the TV, if the back light come on, that means the back lights & the power supply are OK, then you need to replace the main board; if the back lights does not light up, mostly the back light LED strip(s) is bad.

I have an LG TV model number 50ln5100 my screen went black I did a flashlight test and saw movement in the background what part do I need to get my TV working again?


The LED backlight driver controls the operation of the white light. It may be incorporated in the main board or the power supply board. It can also be a stand-alone board. Depends on the model. You can find the parts you need from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

What if the tv is off and the red stand by light is not on what does that mean


The red "stand by" light shows power is getting to the TV. If it is off, you may have no house power being connected. If you can get the red light to come on but your TV still does not turn on the power supply may have failed

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.

When we turn on tv it shut down right away we think it could be the lamp light what else can it be?


Try muting the sound on the tv, if it is a loose circuit the sound vibration can jiggle a connection and cause the tv to turn off as apart of its safety feature.

if the tv functions correctly while in mute then you now know it is a loose circuit.

if the tv continues to turn off even while in mute it is shutting down by the main power stand by safety feature, it may need a new main transformer.

if the muted sound solved the problem then unplug the tv and look in the back for the main transformer, the manufacturer usually places the main board on the box of the main speaker, the speaker could be vibrating a circuit loose from direct contact, the main transformer is heavy and would cause issues over the long run with high fadelity sound systems on big screen tv's. check solder points on main board.
