There should be at least one signal line or device attached with it.

Hi Leigh, I can give you some useful advice on your TV. First thing to do is unhook the ribbon cables going from the tcon to the panel boards one at a time ( they will be flat cables) , then power the set on, if you see a normal half a picture on the side that's still hooked up and white or black on the unhooked side you have a bad panel and the set won't be repairable, if you don't get a good half a picture most likely the panel is ok, then there is 2 other possibilities, bad tcon or main board, this 100% will NOT be a power supply issue like the other posted advised. I'd replace the tcon first as it's much less costly than the main, if that doesn't fix it it's the main, unfortunately there isn't a way to test either board without several thousands of test gear, only option is order a good board. Best place to get boards is shopjimmy.com, however if they're out stay away from ebay, a lot of sellers on there get sets that don't work and part them out with no idea of what boards are bad or good, it's very possible you would get another bad board. Hope this helps.

Sad to say, there are many more displays where LED's fail. Lights have limited lifetime. Even when they are not so bright. The red, yellow or green characters consist of small LED chips on tiny wires inside a number of colored tubes. LED has individual cells mostly connected in series. Therefor one LED element can go out completely, even when it consists of more then one LED. You can repair by interchanging the display unit as a whole but only on the occasion when the display could be removed, the cable has a connector and when made readily available as part. It is wise to disconnect a device with such a display from the power when not in use. As I understand this display is comprehensive so you better rest your case and do as advised.

Question edited for clarity, spelling of 'Aquos' and toss in a load of CAPS. You can't. The television remote is single frequency. Some high end ones will allow a DVD of the same make, but that is already programmed into the Television remote. This seems to think it can, but it is an advertising lifestyles website for Houston. So much depends on the model of the Sharp.

This wouldn't be a HDMI issue, you would have the problem on all the screen if that was the issue. On the left side of the TV (looking from the back) there will be some narrow long boards, some models use 2 some use 4, those are the scan driver boards, chances are that's where the issue is at. It's normal for those to work for awhile when the set is turned on, you could switch them around and see if the issue goes from the top to bottom to confirm this is the issue.

First off, 126 vdc is the backlight B+ voltage using frame as ground, if you measure across the + and - pins on the plug with it connected you should be seeing a couple volts if the backlights are bad, what's happening is the inverter overload is shutting down the minus side, you will always see the hot side voltage of around $125 vdc if the inverter is working. Very good chance you have bad LED backlights as they are known for failure on this and a lot of other LG model sets.

The power supply is bad or problems with the screen or with the the LCD.

Here is the Board Kit for the set. The switching on and off is likely to be the power supply. WiFi issue if likely due to interference, where the television is located and a weak signal. Connecting via Ethernet is always preferable. You can swap boards out and see if it improves the blue tint. https://www.google.com/search?q=lg+43uh6030+board+kit+replacement Our Television Expert is 'Larry'. He may drop in soon. ..
