Solving playback issues

[thathaway3]

I have a Roku Ultra, connected into the HDMI 2 input on a Sony 55" TV.  Everything was working fine and now suddenly when the TV input is changed to HDMI 2 for the Roku, the screen is dimmed considerably.

I have tried EVERYTHING including a factory reset of the Roku and I cannot figure out how to adjust the brightness up on the display.

Does anybody have any ideas how to fix this???

Have you found a solution?  I just hooked up a roku ultra and it is so much dimmer than when I view my direct tv which I am replacing. Changing the brightness setting on the TV doesn't have any effect.

I finally solved the problem by completely resetting the TV to it's original factory settings, in effect a complete "re-boot" of the TV.  It was a bit of a pain, because I had to re-establish the connections between the TV and the cable system wi-fi, as well as reset the connections with Amazon Prime, Netflix etc, as well as the Roku.

But that fixed the problem and so far I haven't had a relapse.

Unfortunately, that did not work for me. If I turn it off and back on it is bright for a few minutes and by the time I pull up a show it is back dim. Very frustrating. At this point I may return it and try another streaming device.

Did you do a full factory reset or initial settings restore on your TV?  That's what I had to do.  The command was somewhere in the settings menu on the TV I think.  If that's what you did and it didn't work, I'm out of suggestions.

Good luck!

On my LG TV, the issue is that different picture settings can be set for each input source (e.g., Roku, DVD player, Xfinity receiver).  When I originally set up the TV (using optimized picture settings from Consumer Reports), I set it for all inputs to use the same settings.  However, I discovered that when I plugged in the new Roku, it used different picture settings that made the picture much brighter.  The other inputs retained the old settings.  Instead of having to reset the TV to its original settings, I was able to use an input other than the Roku input and then use the option to set all inputs to use the same settings (under Advanced Picture Settings).

I have an older LG Smart TV that did not have that option... however, I turned off energy saving option and voila! I can see!

Good thinking.  Thanks for sharing what worked for you.  Always appreciated.

Wondering if maybe your bulb/lamp is going and energy saving feature is trying to save the bulb. (just a thought.)

Could be... tv is quite old for a SmartTV... but when I saw that so many folks are having the same issue... even with brand new devices... I think perhaps it would still have been an issue.
