I have two 55" Sonys, one 4 years old, the other just a year old. The newer one just failed on me. Good thing it's under warranty.
Got a tip for us?

Are new TVs reliable for commercial use?

Chances are the components in all modern TVs from the last decade and such are made by all the big companies. It isn't unheard of for a Sony TV to use inside components from Panasonic and LG, or a Sharp TV to use an LG panel with Sony processor, etc. For a long time, LG used panels from Philips.
Bit strange when you think about it. Your television is essentially the town bicycle. The town being Asia.

I'll take one apart and check the caps. I heard that the LEDs can be a problem too. If one fails the entire panel shuts down. One good thing I can say about Apple is they have enough margins to spec high quality components. Their stuff never seems to break.
Ok, I found out what the main issue is. All the boards are good, but some of the LED backlight elements have failed. This can shut all the LEDs down after an attempted power up. Probably from the power supply short circuit protection? The full replacement LED set is $60, so it's worth repairing. To prevent this from failing again, there is updated software available on LG's website which may help and I will turn the backlight brightness down to let them run cooler.
They are 50" LGs from 2013 and 2014, but other sizes are involved also. I'm not sure about other brands from this period. If anything, it would be good to download and install the latest software and also turn the backlight brightness down on these to reduce further damage.
Update. Our tvs are set to "vivid picture" and 100% backlight which I suspect is cooking the LEDs. I have since turned all of them down to 70%, which should extend the life. We also have a 3 year Hitachi tv with failing LEDs. I was under the impression that LEDs were nearly indestructible, but this is not the case. We are seeing led failures in other applications also.
Damn, just had 2 more LG led panel failures This Week! Turning down the backlight did not save them.
Yes, the Leds are dying after 18 months. The rest of the components seem to be ok. I've been trying to get replacements for a month, but they have been sold out from an independent parts supplier. I can only assume there are plenty of other folks with the same problem.
