Planned obsolescence or just bad luck

So, I updated my Sony XE9005 55" to the latest software last night rebooted the TV everything worked fine.

Next day: No power on, no light in the LED, tried powering of for a prolonged time. Completely bricked...

I've ordered a LG C3 55" which I could get for 7500DKK (~$1100) in comparison a LG C4 is 13500DKK (~$2000).

While I guess it is nice to upgrade to an OLED, then I'm still wondering why my TV just suddenly decided to die the day after a software update. :/

Does that TV have an external power brick? For some reason (I don't know why), I was thinking that they did.

And, if it does, you might want to check the power output of the brick with a multimeter as it might be a bad power brick instead of a bad TV.

When I have a TV that's going in the trash/recycle/whatever anyway, I open it up to check for bad capacitors. That's cheap to fix, while I am less likely to replace an entire power or mainboard for something older, which then usually costs as much as the depreciated value of the set.

Yeah it is an external power brick.

Beyond my skill level and time, unfortunately. :/

It is worth checking, then, as it might be a cheap fix.

If it is bad, I'm sure if nothing else you can find a compatible brick on Amazon or eBay.

By coincidence, I was looking at a display model 65 inch LG C3 just last week. It had a beautiful picture, though for some reason viewing it at an angle caused a very slight greenish tint to appear in the display. It might just have been the store display mode settings that caused it, though.

Anyway, store manager wouldn't let me buy it (it was on clearance, and I think he was probably going to buy it himself as it was being taken down as I was leaving the store).

I agree with checking the brick, although it can still output the correct voltage with no load and still be bad. Recently had a monitor that would shut off randomly. Power brick showed the correct voltage out. so I planned to just replace it. Found a new power supply for ~$15 on Amazon and decided to try it as I could always return it if it didn't fix my problem. Monitor has been working fine for a month or so now.

Power bricks are another thing you can pop open to check the capacitors... though many are "permanently" sealed and it's helpful to have a bench vice or big c-clamp to apply pressure to pop a seam open slightly, then a chisel or sturdy knife to work around the seam... then reseal it with plastic cement if repairable. I don't have little children wondering around and poking at things so I also like to throw the cover on a drill press to make some vent holes.

And, those Sony power bricks do definitely die. I've seen lots of 3rd party replacements listed on both Amazon and on eBay for various models.

If you get a replacement brick PSU, get a major brand if possible. I mean any recognized major PSU manufacturer, not necessarily a TV or specifically Sony brand. Just like generic PC PSU, generic bricks can be dodgy quality.

Companies are actually very good at designing products that fail just out of warranty or making the claims process littered with evidentiary stumbling blocks or misconduct. Indeed, the circuitry might have a failure point somehow that just ends the product's life.

Sony is a reputed brand, but years ago, I got a Element or something that died. Replaced the part, but the replacement ended itself quickly too. Whether the coil varnish just sucked or the normal operating currents just kills things, I don't know, but the product definitely did not last.
