I am setting up a Roku streaming stick + to and older LG TV model 47LH40 and using a splitter to be able to switch back and forth from Spectrum cable to Roku. I was able to easily get the Roku set up and working well. I powered off Roku from the remote and TV went white with floating message power only V04.30.00. Could not use TV remote to control anything and luckily found some posts online how to reset the TV and get it working again. Now afraid to turn Roku on! What am I doing wrong? Do I leave the remote as is and just toggle back the splitter to watch cable?
A couple of questions... What do you mean by "I powered off Roku from the remote"? Rokus (other than TVs) can't be powered off. And secondly, why are you using a splitter? Doesn't that TV have four HDMI inputs?
There do appear to be plenty of reports with that problem with LG TVs, but I've seen it blamed on everything form something failing in the TV to some kind of strange remote signal being sent to the TV.
The same thing happened to me last night with my LG tv. I have a Roku ultra and I was setting up the Roku remote to control the power and volume on the TV. After it was set I pushed power on the TV and the screen went white with the power only and a number behind it floating around and now the TV won't turn off and no remotes will work on it.
I tried to unplug the TV multiple times and when I plug it back in it goes straight to the white screen with power only words and a 4.30.00 code floats around the screen. I have read this has happened to a lot of other people with LG TVs and I don't know what to fix is.
To get out of an LG boot mode, you disconnect power (unplug from power), Press and Hold the TV's manual POWER button for 10-15 seconds, wait 30 seconds or so, and then reconnect power. You should now have power back at TV using the TVs manual buttons. Should also be able to now use the TV's original remote also. However, if you cannot use TV manuals buttons, then normally indicates a problem with the Power Supply Board.
You seem to be describing being stuck in LG's boot-up mode right now with the white screen and POWER ONLY Message.
If the reset procedure above doesn't work, then unfortunately the board likely has a problem and not producing required voltage to proceed. It could be other things, but this is usually likely culprit.
