Hello, so due to some, um, circumstances (aka my kids) and flat screens being easy to break. I've been on a journey to find a LCD/LED tv to replace the one that was broken for super cheap (possibly free). Part of this is because I'm cheap, but also I like to tinker in general and I have a smaller replacement tv in place for now.
So on to the question. I grabbed a sharp lc-50lb150u, that someone literally threw away. I figure I'd just see what's up with it. So I fire it up and the picture is flawless. But, I have no sound.
I don't have a remote, but I do have an old HTC phone that has an IR blaster so I used the anyremote app and put a mostly compatible sharp remote on it. ( it works for everything except the service mode button doesn't work).
I go into the menu on the tv and I see that under sound the speakers are set to "off". BUT it's greyed out, I can't select it to toggle it back to on.
I tried to reset the sound options, I toggled the digital setting between dolby and pcm. I also did a factory reset. No change. It acts almost like headphones are plugged in, so I plugged in some headphones to the headphone jack. No sound there either.
The only thing I haven't tried is the digital out because I need to locate an audio device to connect to that.
I looked on sharp's website, looking for a firmware update as I figured maybe that would fix it. But there are no firmware updates listed on their site to download for this tv.
