I bought the 55" A90j Master Series back in 2022 when it was pretty much new and have been using it without issue ever since. Easy automated software updates for the remote and TV are convenient to keep me updated. I bought the TV to take advantage of some features for the PS5. These two devices connect seamlessly together with the highest quality graphical settings available. My only complaints with the TV are: (1) it doesn't close apps, it leaves them open for fast switching. But let's say you have a lot open, like Netflix, Hulu, Max, Prime, etc., it can slow things down. (2) The TV will "crash" randomly sometimes. This may be connected to problem #1 I mentioned, and I also think it's an ANDROID TV issue and not a hardware issue with Sony. But I've literally had to unplug the TV from the wall before just to reset it. Usually it turns right back on and boots up with no issues. But it can be annoying sometimes. I'd say this happened maybe like 15-ish times in the 3 years I've had the TV. (3) The remote battery life seems to be horrible. The remote does this thing where if you touch it a backlight turns on so you can see it in the dark. It's a nice feature, but it seems to DRAIN the tiny AAA batteries. When your remote battery is low it'll pop up on the TV and tell you, which is also nice. But expect to see that popup every few months... Forever. (4) You ever hear anyone say the blacks are too black? Lol. Well, with this OLED the blacks are too black. The issue is the default setting on the TV is to basically negate color all together on any part of the image that's black. So yes, this does make for "deeper" blacks but sometimes it's VERY hard to see what's going on. It took me a bit to figure out how to adjust these picture settings, especially while gaming. But you can adjust not just the contrast to almost an infinite range, but also the way the hardware adjusts the black level. If you don't like it so dark because you can't see what's happening in movies and games then you can turn a slider down from the settings, causing the TV to add artificial color to black areas, essentially making them more of a dark grey, allowing you to see them better.
Overall, great TV. Would definitely buy the next in line if I could afford it lol.
