The model would have helped. Generally horizontal lines in the picture come from a defective panel and the set isn't fixable, you could try replacing the t-con board but chances of fixing it are slim
If the LED backlight strips were new and you have all the connectors seated correctly it has to be a power board issue, or more specifically an issue with the inverter section of the board, remember its the B- section that is regulated not the B+, start by testing B+ to frame ground and see if you see 100+ volts on both circuits, next test the ripple, I've seen the inverter caps fail on this model a few times, other option would be replace the main board but I'd pull the panel out again and make sure all connectors are good, you can power the set up with the panel out but unhook the panel at the tcon not the panel to be sure the connectors don't short to the frame when it's powered up.
Hi,
Please double check that you've haven't used your remote to remove the display. Some remotes have a "visual mute" option. Also, please ensure that you're tuned to the correct HDMI input. If you accidentally changed it, you might have moved to an hdmi channel or state that has no input.
Thank you.
Hi,
Please plug your rca(?) plug into the corresponding color-coded plug(s) within your JVC device. And if those don't exist, then you can check for an amplifier plug.
Each cable should fit comfortable into it's intended slot.
Thank you.
This positively is a capacitor issue, when the caps are cold, they lose capacitance, if you put a blow dryer at the vents and warm the set up I'm guessing it will power on first time. I'd replace all the caps in the power supply section not just the ones that look or test bad
Your LED backlights most likely have failed and need replacing, it's a common issue with this and many other model LG sets, new strips can be purchased from shopjimmy.com for around $60
It might be because the cord is bad for your TV or the outlet is is not working or there could be a problem with the power supply inside of the TV and it needs to be repaired by someone that fixes TV's.
The T con board is not working correctly with your TV or the cable connections are either broken or loose or the external device are not attached fully to the TV. Or the wiring is not been connected properly.
The tcon board and the screen have now been damaged from when there was a power outage and other components inside of the TV might of had got damaged as well too.It would be cheaper to buy a new TV than to try and fix the TV that is no longer working.
Depends which wireless headphones you have. Most headphones do not use WiFi, they use Bluetooth or 2.4 MHz RF. Usually a wireless headphone set will have a transmitter plus the headphones. The transmitter usually connects to the TV either with the analog L+R ouputs or the stereo headphone jack.
