Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Most likely some components on one of the processor boards have become thermo sensitive over time. This means when they are cold or at room temperature their spec is out. Over time as the circuit board warms up the components drift in to specs. It is time consuming and sometimes difficult to locate these problematic parts. Replacing surface mount components is very specialized and requires proper soldering equipment. If you send the set out for service most likely the service tech will locate and change the complete board that has the fault, if the board is still available. When these TV sets fail out of warranty they are generally not worth to service. I would consider replacing the set...

I have lost two answers I have given. Sorry. Check the input on the remote, it has to be in the correct place. When it is right. Go to set up on the remote, find picture and adjust the colour on the screen. Hope this works for you it has for me. If not restart the router and exchange box if you use that and check input again and the set up. lastly try other channels, it can be the broadcast is not working correctly. all the best kolbrun

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here.

There should be a section in the operation manual that tells you how to set up your tv to view jpg or rlf or whatever you saved with the image and dot following. On the right side of the tv there is a button 2nd up from the bottom you push and it goes to video, hdmi ...one of these should lead you to your usb. We just use the laptop and directly link it to the tv to view such files. If this doesn't help, look up the website for your tv and seek troubleshoot, sometimes there is a person you can "CHAT" with, you may get lucky. Also, if the television is a "Smart TV" , it can even link with your "Smart Phone", you just have to find the manual for your phone and find out how! Sorry I can't be there to help you set it up, but just don't get frustrated that's the main thing. Read everything! You will figure it out!

Remove the board on which the capacitor is mounted, find where it is soldered in on the underside of the board, remove with soldering iron, clean the mounting holes, insert the new cap and re solder. Take note of the Negative and Positive leads before removing the old one and place the new one correctly. I Take this is one of the high voltage capacitors on the power supply board.

change the lead

could be power supply capacitors. see http://www.amazon.com/Repair-42LC2D-Capacitors-Entire-Board/dp/B0084F9R5M

may need capacitor repair kit. see http://www.amazon.com/Repair-42LC2D-Capacitors-Entire-Board/dp/B0084F9R5M

Try switching it back on with the tv remote?

Not sure how you are connected to receive the signal, but if you are not using a cable box and going off air, then either the signal is not coming in from NBC, or your antenna needs adjustment. IF its over the air, its also a digital signal which will tune to lets say channel 4. For digital it will be 4.1 or 4.2 etc. If you are using a cable/sat box to then connect to the TV, call the provider and ask.

Setting menu and it might be under inputs. Check google for the manual and it should explain it in detail as LG had many ways to lock out inputs.

I experienced a similar problem with my 52" Sharp Aquos TV. I called and spoke with Sharp service dept. and they walked me thru the process of resetting the TV to it's original "default" values. It worked great once I completed the steps while on the phone with them. suggest you do the same thing with JVC.

possible lcd issue or broken lcd or T-control board issue plesa give more info or a photo so i can be more usefull

No most of ir sensors are very cheap and the replacement is very easy but make sure that this is tha faulty one because ir sensors are very difficult to malfunction

Yes it can most of no power problems have to do with the Psu of the tv set
