I have an LG tv 43UP77006LB.BEKFLJP. Just recently, having owned the tv for a couple of years, the tv has taken to switching itself on during the night, usually at about 2.00 am. The tv is connected to a TalkTalk box for recording purposes but that has never caused an issue before. It appears to coincide with connecting a DVD player using an HDMI cable to the tv, although it was only connected for a short time and is now disconnected, so it may be irrelevant.
It appears to be a common problem.
Thanks.

My LG G2 bought last November has now started to turn off every 10-15 minutes when gaming on my PS5 which is directly connected. It also from time to time identifies the PS5 as a different device (Shield TV). Any suggestions on how to fix would be welcome.

Hello,
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.
Thanks

I have a problem in browser. My tv is restarting by itself after i play some videos online. On some website's it's working but more website's are not working. In the past it was working great,but after some updates it went to disaster. Past six months it's always restarting. Also on some website's i get message that my browser doesn't support this video but in the past it was working. Looks like LG removed support with new updates. I will never buy lg tv again terrible experience. Android is the way to go. They don't even have another browser to download from the store.
