Blank screen on TV

We have a 50" Samsung TV and last night, the screen went blank. The light for the remote flickers when I hit the power button on button, but the screen remains blank. I swapped it out with a computer monitor, and everything worked fine with the same HDMI cable.

According to ChatGPT, it's probably a problem with the T-Con board (timing control board).

Anybody have any experience like that? The TV is probably 7 or 8 years old.
 

Our problem is we have an aging 55" Samsung. It has 3D.
Scarce 3D capable TVs now are super expensive. If this goes none of our 3D movies will be any good.
So, we put a smaller one on the table under it and save the big one for 3D and the better movies.
 

I have a Samsung older than yours and haven't had that problem. I found this short video that might help you, but I could not find any button on the bottom of my TV. Maybe yours has a button like the speaker is referring to.

There is a button on mine as part of the remote sensor on the bottom of the TV. I tried what the guy in the video said to do (which would reset the software), but it had no effect. I also unplugged it for a minute.

I guess it's time to take the TV apart and find the T-Con panel.

Is your TV three months past the warranty? We never bought another Samsung again.

No, it's about 7 years old. I've had fairly good luck with Samsung products.

I just ordered a new T-Con board off Amazon. It looks like it's coming from China, so it's going to take a couple of weeks to get here.

We'll have to watch movies on a little computer monitor until it gets here. I think I'll set up the monitor on the coffee table to make it easier to see. My hearing isn't so good, so I need closed captioning to be able to understand the dialogue in movies.
 
Did you try unplugging it and waiting a few minutes and plugging it back in. Sometimes these new electronics have to be reset. Hope you get it figured out.

I have a gnat in the back of my tv screen that i can't get rid of.

Yeah, that's the first thing I tried. It didn't make any difference.
 
I know you stated you had unplugged it, but sometimes (rarely) my samsung requires everything from cable box, outlets, outlet strip, etc. to be unplugged. Then there is the whole remote control dance, back and forth. Good luck!
 
I had no idea TVs were so cheap. I just bought a 55" Samsung QLED Q7F for $398 on Amazon!

So, apparently, there are four different LED technologies: LED, QLED, Mini-LED, and OLED. LED is the cheapest. OLED is the most expensive and best quality picture. It has the blackest blacks, among other things, but they're well over $1000. My old TV is just LED and it had a decent picture. The QLED should be a little better. Plus, it's bigger.

I'll still fix the old one and maybe use it in my office, or sell it.
 
Update...

Boy, the difference in picture quality between my new TV and the old one is astounding! There's more refined detail and the action is much smoother! I had no idea there would be that much of a difference!

The only problem I'm having is I can't get sound when watching apps on the TV. The problem is, it relies on eARC technology to send audio back to the receiver, and since my receiver is over 20 years old, it isn't able to process the audio signal. The eARC standard was was introduced less than 10 years ago.

With HDMI eARC technology, only one cable is needed to send the video and receive the audio signal since eARC has a separate audio return channel. Standard HDMI doesn't have the separate audio return channel so my old receiver isn't able to process the audio signal.

So, to get around having to spend another $300-400 on a new receiver, there's a way to get around this problem, and the solution is to use an audio extractor, which plugs into the eARC HDMI port and converts the audio signal to an optical signal, which my receiver can handle.

If anyone else is going through a similar issue with a new TV and an old receiver, this is the audio extractor I just bought off Amazon:

I'll update this post when I receive it and hook it up.
 
what kind of tv did you get that requires an audio receiver?
i have vizio 4k and i just turned it on and adjusted some of the audio settings. i use a regular hdmi cable for hooking the xbox or dvd player to the tv.

You need an audio receiver along with external speakers to get surround sound. You must be using the speakers in the TV.

Yes, I was going to mention that, but I thought maybe you just wanted to fix it your self. :cool:

yeah i don't need surround sound. too loud in an apt building.

i wanted to add this tv doesn't have bad sound for only coming from the tv speakers. there's a setting to make the sound clearer when they talk on the tv as well. don't have to rely on the closed captioning as much now.

We had a 3 year old Samsung 8K TV that did the same as yours.....nothing we tried or videos watched would get it working again.

We finally contacted Samsung Support directly, who determined after some steps, the power module in the tv was bad, and ,it would be more expensive than buying another Samsung 8k TV to repair. But they did offer us a $50 discount on the new TV. Needless to say, we scrapped it.

we now have a Cheaper LG 4K 78 inch TV and its picture is actually better than the old TV; by a lot.

LGs are supposed to be a bit more reliable than Samsungs, but they're also a bit more expensive. I've had good luck with Samsungs, and I got a really good deal on this one, so that's what I went with it. By "good luck" I mean they last 7-10 years, and after that amount of time, their technology has become obsolete, anyway, so I'm forced to upgrade. I can be a bit of a Luddite when it comes to upgrading my electronics. 🤣

Yeah, we always have closed captioning on. Actors don't enunciate any more, so with movies today, even someone with perfect hearing would have trouble understanding the dialogue. There was a YouTube video about that. Actors these days just mumble for some reason. Are they trying to be more true-to-life by doing that? That's one of the reasons I don't like to go out to see a movie any more... no subtitles!

The clarity on the setting on my tv made a world of difference. I can actually hear what they're saying.
