I don't have a Roku. I own a non-smart TV connected to a mini PC. But for folks that don't want to go through that setup, wouldn't using an adblock DNS block it?
TCL TVs (whose OS is just Roku, and I imagine Roku is the same situation) blink the front LED as an Error when there's no network connection or it can't hit whatever servers it has configured for FW update check. It can get stuck on partial firmware updates when it can't cokplete every check it wants to make. The LED has a diffuser on it so it's a significant negative impact.
I can't even tape that LED because that's also where the IR sensor is. My next step is to disassemble the thing and snip snip.
I don't use any smart features, just HDMI input like you. Finding a Dumb TV has been a challenge.
TCL makes Google TV models which explicitly allow you to set them up without Wi-Fi so only HDMI and antenna work. You should buy one of those next time.
Oh good to know. Much appreciated. Thisnines still going strong after 6.5y, great panels honestly. If LED neutering failed I was only going to look for other brands because of this thing so this is super good news
You might want to replace the LED with a normal silicon diode since if I were a piece of shit TV company I would measure that circuit as a voltage divider, and for a complete circuit. No current flow and no 0.6V drop, and that means I activate my out of warranty self lobotomize routine.
That's not something I would have considered and thank you for pointing me in the right direction. Now I know about silicon diodes.
Because this reminded of it: For a similar reason, and if you own an older vehicle, you don't want to replace the warning lights (battery, oil, engine/MIL) with LED bulbs. Or you'll need "error free" bulbs with built-in parallel resistors. LED gauge lights are usually fine but, on a lot of vehicles, an incandescent bulb is expected on the warning light circuits. If you replace, for example, the battery bulb with an LED - the alternator might not engage as it should, because there won't be sufficient current for it to do so, and your battery could drain despite a running engine.
(I'm far from an electrician, nevermind an automotive one, but I did a lot of research before upgrading/replacing my burnt out dash lights and that's a mistake I would've otherwise made)
I did a factory reset on my TCL roku tv and use a third party streaming box. Blinking red light on the TV went away after the factory reset for me.
Ooh, definitely gonna try this first. I actually assumed that factory reset would use the 1y old firmware that introduced the problem, but it could well roll back to the 6y original.
Don't worry, the next model they release probably won't allow you to do that.
