Samsung TV Won't Turn On | PROVEN Fix!

Samsung TV’s can be a bit finicky when it comes to power. Here is what to do when your Samsung TV won't turn on, or isn't working:

(timestamps)
00:00 - start
00:45 - power standby light
02:05 - power-cycle your TV
04:22 - power-cycle your remote
05:07 - reseat the power cord in the back of your TV
05:47 - try plugging your TV into a different power outlet
07:08 - make sure your TV is on the correct input source
08:14 - hardware issues (T-Con board, main board, power-supply board)

If none of these fixes work you might want to pull up your warranty and see if it is still valid, otherwise you’re stuck buying a new TV.

I was ready to order a power supply board when I saw your video. THANK YOU!!! Your advise to pull plug, disconnect surge protector, and reset WORKED wonderfully. We pair over $400 for our un50tu8000fxza Samsung TV 3 years ago and we were distressed that we may need to discard it. We are retired and $400 for a new TV would hurt. Thank you again for selflessly sharing your expertise with others.

I moved my Samsung to another room... would not turn on. Found your video... pulled the plug... found the manual power button and held it for over 15 seconds. Waited 30 seconds, then plugged it back in... and voila! It turned right on. Thanks so much, there is no way in hell I would have figured that out...

…thank you SO much 😭😭I had tried everything, bought a new cord, left unplugged forever and had just accepted my 2 year old tv was screwed but THIS fixed it after months using my laptop to watch stuff, thank you soooo much 😭

This works!!
I have a Samsung LN S4051D that, out of the blue, wasn't turning on and no standby light at all. My power button on TV is on the front bottom middle and standby light is on the power button. This button hasn't worked in years.
I unplugged it from both the wall and back of TV, held power button down 15 secs then actually waited 20 mins before I plugged everything back in.
But mine wasn't instant, it took 30 mins before the standby light came on and I was finally able to turn on TV.
But thank you SO much for this video!!

Was ready to smash my TV until i found this video! Unplugged and held power button on the TV for 15 seconds. Waited 30 seconds to plug back in and turn back on and...BOOM!!! MANY MANY THANKS SIR!!!

This is one of the best and most through videos we have ever seen. EVER! Haven’t tried these fixes yet but wow so detailed. Thank you. You took nothing for granted. Fantastic. Whether my tv works again or not, thank tou

Phew!!! Just fixed my old 32" Samsung that suddenly stopped working a few days ago for $0!!! Had a black screen of death with a steady standby light. No picture, no sound. Power cycling the TV did the trick! None of the other videos I watched (a bunch I tell 'ya) told me about holding in the power button for 15 seconds to discharge the power from the capacitors. Thanks so much for providing this valuable info!

Let me add my name to the list of people whose TVs you have saved. I unplugged the TV, held the power button for, actually, more than 30 seconds, waited a few minutes and plugged the TV directly into a nearby socket, instead of into an extension cord into a distant power cube (because I thought the nearby socket didn't work, but I guess it does). Bada boom! Fixed! Thanks for saving me from going to Costco and buying another TV.

Thank you for very clear instructions on how to reset the power(reboot). It worked great.

[LDotRich]

IT WORKED!!!! My power light was flashing red and my TV kept cutting on and off. I unplugged the tv. Held the power button for 15 second then released it. I then waited 30 seconds and then I plugged my TV back in and it turned right on. I was afraid I would have to buy a new one lol. Just saved a lot of money following these steps💰

[vageraci]

Your steps for troubleshooting which of the internal boards was the culprit were perfect (blank screen, but sound was good)!
I replaced the T-ConBoard - nope, and then the Powersupply-board - Bingo!
Also – best advice – take the back of the TV off and TAKE PICTURES to make sure you replace the board with the EXACT board (because there are different revisions, etc.).
Thank you for the advice. I really did NOT want to throw out a 62" TV.
Less than $100, and it's back in action. Thank you!

This guy is a genius! I did the power cycle and it fixed the problem, tv is back on.

[ltreyno]

Thank you. Plugged it in the wall directly pushed the plug hard into the back of the TV turned on! thank you

I liked your thorough explanation coupled with visuals regarding this topic. Top shelf.

My Samsung UN55KU.... suddenly would not power on, but I was able to somehow get it on one more day before it would not come on anymore. I put it away for about 10 days switching to a 40 inch that I did not like. But because I was able to get the Samsung on briefly, I resisted trashing it. Thankfully, I saw this video before pulling the trigger this Cyber Monday. After one last third attempt holding power button for 60 seconds (and changing my remote batteries), I was shocked to see my TV power on again. I am so grateful☺ Thanks Much!!!

Thank you so much on such a detailed explanation. After a simple power cycle, the TV is back up and functioning. I was within minutes of hitting the purchase button for a new TV. Now I recognize the red power button is a great tool to help isolate and provide direction (after you explained the functionality of it). Great tip...Thank you!

[maricelaibarra]

Thank you soooo much. I just did what you suggested. Located powerbbutton, held it forb15 seconds, unplugged TV from surge protector, took plug out from back of TV and then plugged the TV directly to the wall. Also did the same with the remote. Voila! It turned on. Thanks again.

[brunoaziza]

awesome work and very detailed. really appreciate it. unfortunately I think my TV is dead but I appreciate the work that was put into this video. Thank you!

[dollbaby]

I worked and worked finally figured it out the power cord came unplugged..Thank you😊

[bigstyx]

I fixed it with a hammer and a bottle of vodka. And a trip to Costco
