I have a 65" UN65JS850DFXZA Samsung TV that will not power on. There is no red standby light. Nothing happens. Any suggestions would be great. It is not the remote. The set has power. I have unplugged the one connect device. I have left the set unplugged for hours. Still nothing.

lainiest if you have guaranteed power to the set it is likely you are having an issue with the power board. You will have to unplug it and remove the back of the set. Then check the power board for any blown fuses or other components. You do want to post pictures of your boards with your question so we can try and assist you further with that. For that use this guide The attached image should show the fuse on your power board. Check for continuity and see if you get power to that, once it is checked. Unplug your set to check it for continuity. Then plug it in and use your meter to check for power.

Erm...this is great if you know what the heck you're talking about lol what about advice for us novices?
Cass Ababio but that was for novices :-)) What make and model is your TV? What are the symptoms? What have you checked? What tools do you have available (multimeter etc.) and what are your abilities? I am more than willing to guide you through things step-by-step.
This statement about continuity is not accurate. Verifying continuity means that you are checking to make sure there is a complete electrical path/connection between 2 points with minimal resistance. And on these size fuses, you will most likely see resistance around 0.1-0.2 ohms. That is important because you can compare the fuses against each other. If 2 of them give you a resistance around 0.2 ohms and the other shows 40 ohms per say, I would go ahead and call that a bad fuse even though you were able to get some kind of reading through it. You will also need to remove one side of the fuse from the circuit in order to accurately measure the resistance. Other wise you can get a false indication of a “good” fuse.
I have a 32" LED TV name D:Sign Model no "sty1232c red light on but it doesn't turn on screen it is blank
year old 4k Samsung 0693CZH70060F tv power wont turn on what size tool do u need to remove the back plate to access the power board Already plugged it in and unplugged it held down button 1 min to remove any residual power Just like u would a lap top or phone what size socket do you need to remove the back plate. Also if it is the fuse how do you replace it seems to be fused in and not a easy replace based off the Picture.

Hi, Was there a storm or blackout between the time when it was working and when it wasn't?
have you tried disconnecting the power cord and pressing the power button on the TV for 30 seconds then reconnecting the power cord turning on the power outlet and then try turning on the TV?
Is the power cord connected directly to an outlet or does it come via a powerboard? How have you proved that the set has power?
crwdns2934105:0crwdne2934105:0
It worked for me!!! Thank u jayeff!!
I tried the comment about turning off the TV and hold the power button for 30 seconds. I tried that and it didn't work. Then I thought, how can holding the power button do anything, when there is no power. So I tried holding the power button while the TV was on and it worked.
Hi @swanless ,
Holding the power button on when there is no power supplied to the TV allows any "residual" power that is in the TV to dissipate.
By doing this what is hoped will happen is that if there is any corrupted data (caused by a power surge for example) which prevents the firmware from functioning correctly will be deleted (or lost) and the TV will revert back to a default operating condition. Obviously this can't happen if the power is still connected to the TV
You may not believe this but it is usually the first thing most electronics techs (and help centres) do as it can resolve a lot of problems. It is known as a "power refresh" and it can be surprisingly effective in a lot of cases.
Thank you, jayeef! Your solution still works for newer Samsungs, too!
This unfortunately did not work for mine. I am at a loss :-(

On the power board, there is a relay (its what clicks when you power on). If you tap on the relay (becareful , use the plastic end of a screwdriver), the power should come back on. The relays are crap..

Hi, my tv was unplugged for the weekend then when id tried to plug in it wouldn't turn on. My hubby has opened it up and checked there seems to be no problem with the fuse but he says there is no continuity as the treading has worn off or something like that. Problem is he says he needs to solder the board but he has tried using the thick solder wire which isn't taking. I've been waiting a month now missing all my shows for him to sort it out. Is there anyway I can solder it with the thick solder myself? I'm tired of begging him to get proper wire or to fix it for me.
Melicia H you need to let us know what make and model your TV is. After that tell us where and what your husband wants to solder. How thick is the solder? You soldered before? "no continuity as the treading has worn off " explain this a bit better.
Hi. My problem is exactly similar to what is posted above. my Samsung TV went off abruptly and since then the red signal light doesn't come on, I have tried all that is mentioned above, checked the fuse and it was continuous, tried to hold the power button for 30seconds with power cord off and with it on and even tried to gently tap the relay but still no success. Help.
Tv turned itself off after watching it for 20 min. No red light. Tried all those tricks above and nothing worked. Warranty just ended last month. And it’s Good Friday. No chance of getting anyone here for days. Model UA60J6200AW. Help!!!
I have a Samsung TV that has a touch screen power button. It worked perfect until we unplugged it to move and now it will not turn on. No red light at the power button. We have two of the exact TV doing this.

Hi @ Vivian Gosselin,
Did you try a power reset, you didn't say?
Here's how:
Switch off the power outlet (if it has an On/Off switch) that the TV is connected to and disconnect the TV power cord from the outlet.
Press and hold the TV’s Power button for 30 seconds to dissipate any residual power from the TV.
Reconnect the power cord to the TV and switch on the power outlet (if it has an On/Off switch)
Try to turn on the TV.

because I was wrong…the red light is on. Sorry & Thank you
@jayeff , I have a samsung UN50MU6300F that suddenly turned off. We tried to turn back on with no luck. Unplugged...did not turn back on. I cannot locate a power button to do the power dissipate. Any thoughts on what to try next?
Hi @mcorl,
You may have to follow the directions as supplied in the Chosen Solution above.
I don't know your model but if it is still covered by the manufacturer's warranty go the warranty route first before removing the back off the TV.
I have tried everything you said but no respond of the red light and my TV is 4 weeks... please help.
Hi @viola kuria
Have you tried the TV control buttons instead of the remote control?
Do you mean that the TV is only 4 weeks old from new? If it is call the manufacturer's customer service as it will still be under warranty
Every time I’ve experienced anything like that, I finally figured out I just need to pull the plug, do the 20 to 30 second wait, and plug back in. Always works for me.

It didn’t work for me ?
My COBY TV standby light is not coming on.It's a new TV that has been on basement for a long time.I plugged it to power but not even a redlight.What do i have to do?
Before replacing the power board, check for cold solder joints on the large square component (not sure if it is a rectifier or voltage regulator, but it gets hot when the TV is on). My Samsung would stop working, no red light and sometimes after sitting for hours it would work again. The heating up/cooling down of this component must have put stress on the solder joints and caused breakage leading to intermittent contact. Reheating/reflowing the solder has fixed the issue for me.
Look for rings around the terminals where the solder had broken. Good luck.

The same problem. When I plugged in the usb, it did not show the files on the screen. Then I plugged the usb out, suddenly the tv shut down. And when I tried to turn it back on, it did not. And nothing happen. I tried several times but it's still dead. What might be the problem and how can I fix it?
