Worth checking
58ut9850 rechargeable remote ignores most button presses within 2 months
An owner of the 58ut9850 reports the bundled rechargeable remote stops registering most button presses within about two months of purchase, despite a full battery; only the Netflix and power keys respond.
What to check. Before buying, budget for a possible remote replacement or service visit; the remote is the most-reported problem specific to this model. Verify the remote works fully during the return window.
58ut9850 'magic remote' voice features not working as advertised
A buyer of the 58ut9850 says the dealer sold the TV on the 'magic remote' voice features (channel change, voice app entry), which the owner reports do not work as promised.
What to check. If voice/remote control matters to you, test those features at the store before purchase; this is a reported gap between advertising and actual behavior on this model.
58ut9850 installation/service mishandling reported by owner
An owner reports the authorized service technician logged the 58ut9850 as installed without completing setup, blaming a satellite line that was not the cause; the owner fixed it themselves.
What to check. This is a service-quality report rather than a product defect, but it suggests you should verify installation is genuinely completed and not just logged.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
