I recently had to reinstall the Streaming Stick+ on my LG TV.
Before it worked fine but now whenever the TV is turned on, the bouncing ROKU appears for a long time, then the screen goes black and finally the Roku menu appears. It works fine after that. It used to boot up instantly.
I have tried different HDMI ports and a factory reset but it did not fix it.
Is this an indication that the ROKU hardware is failing, or does it point to something wrong with the TV USB port?
I've never seen a Roku streamer that "boots instantly" - they always have to do the standard boot process (check internal hardware/software, detect/check connected devices/configuration etc), which depending on model, connected device/configuration, and # of apps, takes between 15-30 seconds (changes in firmware, connected device, and configuration can/do affect boot time to Home)
The only way it can "boot instantly" is if its already booted - which requires it be independently powered from the TV/AVR - if you are using a TV/AVR's USB port, that is rarely going to be the case (almost always, the USB port powers on with the TV on, and off with the TV off).
If you want the Roku to be "instantly available", then you need to have it powered by an always on USB connection (e.g. via the wall adapter).
With an LG TV, its possible you enabled its "Quick Start+" setting, which makes the TV itself come instantly on, revealing the boot process of the SS+,whereas otherwise the TV itself has a longer boot process (masking the SS+'s boot process powered by one of its USB ports).
Perhaps there is a setting on the TV that determines if the USB port remains powered up or shuts down with the tv - or maybe more than one port, one that shuts down and another that stays powered.
