• Another LG OLED user reports power cycling issue caused by bright flashes
• Reddit user u/RandomGamer414 reported the issue with their LG G5 in the r/LGOLED subreddit
• Other users report similar issues with different LG OLED TVs, caused by other games and streaming

More LG OLED users are experiencing power cycling issues caused by bright flashes on screen, and the models and causes are varied.

Last week, we reported on on unfortunate Resident Evil Requiem player's LG OLED turning off when they fired the titular weapon, with the bright flash from the gun seemingly causing a power cycling issue on their LG C1. Reddit user u/yorgo332 reported this issue in the r/LGOLED subreddit.

Well, now another Reddit user is experiencing a similar issue, only this time it's with an LG G5, the brand's flagship and one of the best OLED TVs from last year. Check out user u/RandomGamer414's post below:

Once again, it's a bright muzzle flash from a weapon (this time in the game Cronos: The New Dawn) that's causing this user's LG G5 to turn off and turn back on again.

Further exploring the Reddit thread, it seems like it's not only a wide variety of games causing an issue, with Halo 4, Rocket League, The Division 2 and Borderlands 3 all named, but some users experienced it watching content through streaming sites such as Netflix and Hulu. The majority of reported issues do stem from video games with big flashes from explosions, however.

Users are also reporting the issue on a number of different models too, going as far back as the LG C9 (first released in 2019) and as recently as the LG G5 (which is the model u/RandomGamer414 is using in the post above). The CX (2020) and B4 (2024) are among some of the other models named.

It's worth noting that there are plenty of other LG OLED users, including G5 owners, who are saying they've never experienced this issue before. We here at TechRadar regularly use the G5 as our reference TV for testing, comparisons and our Blu-ray Bounty feature and have also never experienced this issue. We also have an LG C5 and LG B5 at our testing lab and again have not experienced this issue before with either of them.

Again, it's not entirely clear what is causing the issue, whether it is a power unit failure or a problem with the panels themselves.

Some users are suggesting that a new HDMI cable could fix the issue or adjusting the TV's brightness to dim the flash to prevent the power cycle from happening, but there seems to be no obvious fix as of yet.

We have reached out to LG for comment and will be sure to update this article if we hear back.
