Got my LG C4 OLED last year and lately I've noticed these small purple/magenta spots showing up randomly on the screen, especially during dark scenes. They come and go, and I'm worried it might be burn-in starting. Should I be concerned or is this something that can be fixed?
Burn-in would show up as permanent ghosted images, not random purple spots that come and go, so that's probably not what you're dealing with here. What you're describing sounds more like a pixel issue or a temporary glitch in the panel - LG OLEDs occasionally have stuck or malfunctioning pixels that can appear as colored spots. Since it's still under warranty (you got it last year), I'd contact LG support and describe what you're seeing; they can often replace the panel if it's a defect. In the meantime, try power cycling the TV completely (unplug it for a minute) to see if that clears it up, though if the spots persist, a warranty claim is your best bet.
Try a factory reset first - random colored spots that flicker on and off are sometimes just temporary glitches in the panel electronics rather than permanent hardware damage, and a reset can clear them. If they persist after that, you're looking at a warranty claim since those OLED panels are sealed units.
I had something similar crop up on a display I was troubleshooting, and those random colored spots that blink in and out are usually dead or stuck pixels in specific areas of the panel rather than burn-in or a widespread panel failure. Since your LG C4 is still under warranty (should be at least a year, probably longer), contact LG support with a photo or video showing the issue - they'll likely replace the panel if it's a defect. The factory reset suggestion isn't a bad first step if you want to try that before calling them, but honestly if it's a pixel problem it won't fix it, just rule out software hiccups.
Don't assume it's a widespread problem yet - those random purple spots could be stuck pixels in just one area rather than a systemic panel failure. Before you contact LG, are these spots consistently in the same spot on the screen, or do they genuinely move around? If they're fixed in location, you're likely looking at a few dead/stuck pixels that might need warranty service, but if they're truly random and fleeting, running the factory reset the other person mentioned is still worth doing first.
before you do anything, check whether these spots appear in the same exact locations every time or if they jump around - that detail actually matters a lot for what's happening. stuck pixels stay put, while random electrical glitches tend to wander or disappear. i had a panel act up years back where purple artifacts would flicker during specific scenes, and it turned out to be a firmware hiccup that cleared itself after a couple weeks of normal use, so patience sometimes wins here. if the spots are genuinely random and transient, a factory reset does make sense like others mentioned, but also just give it some time - don't panic into an rma claim right away.
The random appearance and disappearance actually points away from stuck pixels - those typically stay put - and more toward temporary glitches in the display's processing or minor sensor errors, which a factory reset might genuinely help with. Before resetting, check if the spots appear in specific apps or inputs (like a particular streaming service or HDMI port), since that'd suggest a software issue rather than panel damage worth claiming under warranty.
Are the spots appearing in the same physical location on your screen each time, or genuinely random across different areas? The reason I ask is that stuck pixels and dead pixels are usually fixed in position, so if yours are actually moving around or appearing in different spots, it might point toward something else entirely - possibly a connection issue between the panel and the driver board, or even interference. A factory reset is worth trying as others mentioned, but if the spots persist and keep shifting locations, that's actually more of a warranty claim situation than a pixel problem, since LG should handle potential panel defects within the first couple years.
Purple spots that flicker in and out aren't something you should panic about or assume means the panel is dying. I've seen this happen with my own TV where a few pixels would do weird color shifts during certain scenes, and it turned out to be stuck pixels rather than anything progressive - they stayed in the same spots and didn't spread. The good news is that if they're confined to specific areas and not constantly getting worse, LG's warranty should cover them since you're still within that first year window. Document when they appear (which scenes trigger them) and grab some photos or video if you can, then contact LG support with those details - they're usually pretty good about replacing panels under warranty for defects like this rather than making you jump through hoops.
Saw something similar happen with a friend's panel where random colored specs would pop up during streaming, and it turned out to be stuck pixels rather than anything systemic. The good news is these tend to stay in the same spot if you pay attention - so track where they appear over the next week or two. If they're consistently in one area, you're looking at a localized pixel problem that LG should cover under warranty, especially if the TV's only a year old. If they're genuinely random and moving around, that's more likely a temporary glitch and a factory reset could actually solve it, though if the spots persist after that, definitely contact LG about a replacement since you're well within the coverage window.
Don't go nuts thinking your panel is dying - random spots that flicker in and out are usually just stuck pixels, not the permanent ghosting you'd see with actual burn-in! The thing everyone's missing though is that if these spots only show up on specific colors (like only during dark scenes with purple content), it could be a software glitch in how the TV's processing that particular color range, so before you do a factory reset, try adjusting the color settings or checking if there's a firmware update available - sometimes LG pushes fixes for quirky display behavior like this.
