Vizio 1.60 defective firmware update -- victims post here
This thread is for people whose previously perfectly-working Vizio TVs have been degraded by their forced 1.60 firmware update. It is intended to collect input only from people who have been affected, in order to raise awareness and get Vizio to officially acknowledge the problem. A handful of people have gotten responses from their support team indicating they know of a problem, but some CSRs still deny any knowledge and their Twitter support account is ignoring people.
If you post in this thread, state your TV model number, exact firmware version, and confirm if you're seeing the issues on the Known Issues list (below), and if you have any other issues that aren't on the list which others might be able to verify. Specifically, this seems to affect firmware version 1.60.10-004.0090 from what we know so far.
Background (as I know it, please feel free to add/correct and I'll edit):
In late 2014, Vizio began pushing out a firmware update to 2014 M-series TVs, which are full-array LED sets with local dimming, and 2013 M-series TVs, which are edge-lit with local dimming.
After this update, people began noticing issues with LED dimming performance. Because Vizio silently pushes out firmware updates, many customers got this update without knowing about it. By the time the issues were known within the community, it was too late for many users (like myself) -- they had already received the 1.6 update and were stuck with it.
A number of users have contacted Vizio support, and were varyingly told things to the effect of (1) there's no problem, you're imagining it; (2) there's a problem with your specific TV, we can replace it if you want; (3) there might be a problem with our firmware but we're not going to actually admit to that, and there's no timeline for new firmware.
Please comment if this list is incomplete and I'll try to keep it up to date -- we will only add to this list if someone else with 1.6 can replicate your issue
1. Sluggish dimming - While this is hard to quantify, many people have reported that the action of the LEDs dimming is way more noticeable after the update. Additionally, when going from dark to light scene, it seems to initially overcompensate and "blow out" the whites/bright colors before settling down to where it should be.
2. Active LED zones setting is ignored - If a picture profile has Active LED zones set to "off", this setting is ignored when the TV is first turned on (the zones dim anyway). The only way to fix this is to go into the Picture settings and cycle the setting to "on" and then back to "off" again, every time the TV is turned on.
