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.
It's possible you damaged the tcon. When you connected the ribbon connectors going from the tcon to panel boards you may have damaged the tracers, remove the connectors and see if those are bent or broke off. Another possibility is the panel was damaged when it was handled, you need to use static protection when handling the panel, if this wasn't done it could be damaged
There might be either a cable that is loose or not connected properly or there might be a problem with your TV's hardware. I would try to first re set the TV by unplugging it and everything else that is connected to the TV for about 1 minute and also press and hold the power button for 30 seconds too and wait a couple of minutes to plug the TV and everything back in.
This problem is related to the mainboard and should be replaced. You can try to heat up the microprocessor with a heat gun though best solution is to replace mainboard. Part number is EBU60864321.
Hope this helps!
Well you have covered the main two, overheating and failing capacitors. The only other one I can think of is a component / IC dry joint on the circuit board. As the board heats up, the connection fails. Or something is failing internally when heating up.
