This is a much asked about question:
LG Smart LED TVs that turn on for a second, show the LG logo, then a black screen ensues.
My TV is a LG 43uj6200 TV.
I have tried the typical troubleshooting steps involving holding the power down for 15 seconds while unplugged, then waiting up to 15 min, then holding down the power again while it turns on. No fix there.
I am getting the 3 red blinks, but the system will stay on (at least the motherboard does). 3 red blinks indicates that it is a power supply issue, from what I read.
Also, I visually looked at the mainboard for faulty caps (leaky or busted cans). Nothing visible. I have read that there is a power diode that could be bad. I did a diode check on all diodes near the "blue rectangular component" (possibly a relay?) None of the diodes showed an open circuit or an infinite voltage.
I do not have an ESR/LCR meter but am going to get one in a few days.
I measured the voltage on the output of the power board and it is supposed to be 13.2 volts. I got 13.08V. Measuring the second to last pin (P-ON), I got 3.2V. I am not sure if that is up to par. I think 3.3V is the requirement for the mainboard.
The last pin at the bottom of the connector is called INV-OK or something like that. I measured 2.85V there. Are these voltages within spec?
I have also read that the LEDs could be open circuited or failing which would draw more current than the power board can handle. This could also cause the shutdown.
Does anyone have any other repair tips for this? I really don't want to have to buy a new power or mainboard.
So the other day I started installing a new game on my Xbox, and turned off the TV, leaving the Xbox on. The next I was turning on the TV, and it's a black screen. Using the remote, I get a message saying that "Smart Services will soon be available", just before it reboots (shuts down and automatically turns on again). After that it's stuck in this loop until I remove the power cord.
The things I've tried so far:
Disconnect both HDM-ports and restart Disconnect power cord and re-enter while holding down the power button on the remote Holding down the power button on the remote for 4+ minutes Holding down the power button on the TV (beneath the logo) for 4+ minutes Disconnect power cord for >28 hours and reboot Removed batteries from remote control and reboot Inserted a USB-stick with latest firmware to the TV and rebooted Nothing of this has helped. Any more ideas?

Communications technology works in devices like smartphones to offer us increased convenience, keeping us connected with friends and family and providing an endless source of entertainment.
This technology can also be applied to mobility. Like a smartphone, a vehicle is equipped with communications technology that connects it to the internet, enabling passengers to do more on the move through automotive displays that show key information including directions, driving information, nearby restaurants and the news.
The technology that connects cars to the internet is known as telematics.
A portmanteau of ‘telecommunications’ and ‘informatics’, telematics refers to the use of on-board communications-enabled devices to store, send and receive information. A car collects data from various sources, including mobile networks, Global Positioning System (GPS), Location-based Services (LBS) and Intelligent Transportation Systems (ITS), which is then analyzed through telematics to provide the driver with all the info available.
So, why is telematics so important?
Core technology for autonomous cars
Autonomous cars must be able to operate without human intervention. With analysts predicting autonomous vehicles to generate as much as 40 terabytes of data every hour,* almost instantaneous communication is essential for self-driving cars to exist in a world that puts safety above everything.
Autonomous cars need to be able to detect all kinds of information using several cameras installed onboard, including data on local traffic, traffic signals, other vehicles and in-cabin conditions. The information is then transmitted to the cloud where it’s analyzed to achieve fully automated driving, a process which is faster and more accurate thanks to telematics.
Real-time updates for cars
Over-the-air (OTA) automatically updates a car’s software via wireless communications, reducing the need for service center visits for repairs or replacements and meaning new services that weren’t available at purchase can be added later.
With the modern car constantly evolving, communication with servers containing upgrade data must be seamless so that cars can automatically check for and apply updates and menus as soon as they become available. Telematics ensures this fast and accurate communication without error.
Connect via the internet
With most of today’s devices having access to the internet, we’ve already experienced how internet connectivity enhances convenience in many ways. In fact, we have come to trust and rely on communications to a point where we almost can’t live without it.
The same applies to the automotive industry, which is why Wi-Fi-enabled cars are on the rise. From receiving traffic guidance and requesting assistance during emergencies, to tracking the locations of stolen vehicles and sending high-resolution videos, telematics brings various features together to make the driving experience safer, easier and more enjoyable.
As we enter the 5G era, a more diverse and differentiated in-vehicle experience is on its way. However, reliable telematics will be key to ensuring a stable 5G connection as well as the outstanding quality of services like autonomous driving, vehicle-to-everything (V2X) systems and connected cars.
To prepare for what’s to come, LG Electronics’ Vehicle component Solution (VS) Company has been focused in on the R&D of its telematics for several years. For example,

To carry this momentum on, LG will continue to work with global partners to develop the telematics systems offering the most enhanced convenience and safety to millions of drivers the world over.
