My lg 49UH850V screen has gone crazy
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.

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.
Does anyone know about fixing LG TV's
Don't suppose you have a re-flow oven. If it worked for awhile after soldering on the main board I'd try re-flowing the entire board, sounds like some cold solder joints if it worked for awhile after soldering. Not sure how a grounding issue would make half the picture have issues however but anything is possible.
How do I link LG AKB73615337 Remote Control to my xfinity flex box?
The LG AKB73615337 remote control is designed specifically for LG TVs and may not be compatible with the Xfinity Flex box. However, you can try the following steps to see if it works:
- Ensure compatibility: Confirm that the LG remote control is compatible with the Xfinity Flex box by checking the list of supported devices in the remote control's user manual or by contacting LG customer support.
- Power on the Flex box: Make sure your Xfinity Flex box is powered on and connected to your TV.
- Activate pairing mode: Put the LG remote control into pairing mode by simultaneously pressing and holding the "Back" and "Home" buttons for a few seconds until the LED light on the remote starts blinking.
- Follow the Xfinity Flex box pairing instructions: Refer to the Xfinity Flex box's user manual or contact Xfinity customer support to find the specific instructions for pairing a remote control. This process may involve entering a pairing code or following a series of steps on the TV screen.
- Test the remote control: Once the pairing process is complete, test the LG remote control to see if it works with the Xfinity Flex box. Try navigating the menu, changing channels, adjusting volume, and performing other functions to ensure proper functionality.
If the LG remote control does not work with the Xfinity Flex box or if the pairing process is unsuccessful, it is recommended to use the original remote control that came with the Flex box or consider purchasing a universal remote control that is compatible with the Xfinity Flex box. Universal remote controls are designed to work with multiple devices and usually come with instructions for programming them to work with specific devices.
Remember to consult the user manuals of both the LG remote control and the Xfinity Flex box for specific instructions and contact customer support if you encounter any difficulties during the pairing process.

I assume you changed all the LED strips when you changed the bad ones, NEVER replace part of them, if you didn't replace them all, open the set up again and replace the ones that weren't replaced the first time and all will be well.
