That's sarcasm and/or corporate-speak, just like every software nowadays has telemetry and diagnostics and yet the quality of it is much lower than a decade ago before any of this BS. Just that if they called it by stalking and/or marketing tracking there would be an outcry, so "diagnostics" it is.

One of my TVs would regularly lock up when trying to decode a particular iffy signal over the air. In theory, a core dump could have helped fix that. In reality, that tv got zero updates.

Another tv had some bad joints on the panel, but remote diagnostics weren't going to help with big giant vertical lines.

With more than a hint of irony, the only TV I had 'break' was when Sony's telemetry server went down, and my Bravia TV failed to turn on. It wasn't until I happened to unplug the Ethernet cable that it suddenly started working again.

This was a little under ten years ago.

Had one fail: a flex cable went loose.

Just reinserted them all back in and voila.

The LEDs or drivers sometimes die, but replacements are usually available from ebay or aliexpress.

Funny how one of the repairers found that his 120V only LCD TV had a 120/240 power supply board nonetheless.

My dumb Samsung did way back in 2011. It was a POS and I vowed never to buy another Samsung TV ever again. This gives me further reason to hate Samsung.

Exactly
