My TV (Samsung Smart Tv 32Inch UA32M5500ASXNZ) has recently started doing this thing where the screen randomly goes black, while sound still works. When I turn my TV off and on again, the screen works as before. How long I off it for doesn't matter- it works even if I turn it off and then immediately turn it back on.

Once on again, it will work for a few minutes (3-7mins, and then will fade to black. I've tried doing a soft reset and changing the power cable, but to no avail. I've also checked the timer and eco sensor and turned off the automatic dimming in case that was the issue, but still nothing. 

The screen has also had 2-3 flickering lines on the top and bottom of the screen for a few months now, but that seems to be a non-issue. They're very fine so it doesn't really cause much of a hindrance while watching stuff.

 

When it blacksout, there is still backlight, like a normal black screen (not as though the TV is off), but I can't see any color when I shine a torch to the screen. This started around 4 days ago, it randomly worked fine for 2 days after the first day it started acting up, and now it's back to blacking out.

 

Any advice on what the issue could be, and how to fix it?

Thank you for your reply. 

 

Unfortunately this did not work. There are no software updates and the self diagnosis only includes picture and sound, not software. 

Anything else I could try?

Here is a generalized idea of what's happening with your Samsung Television.

"Samsung 32" Full HD Flat TV M5500 Series 5" (UA32M5500ASXNZ)

It's unlikely that the issue you're experiencing with your Samsung Television can be resolved by performing the procedural troubleshooting steps. Usually there are a number of them. However, it sounds unlikely that they will resolve your issue.

As far as the issue you are experiencing from what symptoms you do mention. It sounds like there's a problem with the power board side of your Television. That's not to say that it's just the power supply board or just one issue. The issue you are experiencing is the internal system that protects the Television from further damage.

It very well could be that there are LED Strips that have gone bad. The internal Power Supply Expects an expected uptake voltage to the LED's. The LED's are supposed to consume that expected power. When it senses that the LED's aren't consuming the power they should be. It will cause the Television to shut off.

I hope that I have given you an idea as to where to look. I don't work for Samsung nor can my advice be taken as being for Samsung Corporation or any of it's Affiliates. Depending on the age of the Television and how much you want to pay? You could have it repaired or fix it yourself. My personal opinion.

Once again Thank you for using the Samsung Member's Community and thank you for your question regarding your Samsung Television. I hope that I have been of assistance to you with your questions. Thank you!

Thank you so so much for your reply! You did an excellent job of explaining it to me. I figured as much, I have done almost everything short of opening it up and tinkering with it myself, but to no avail. I assume it is the led strips, as when it does black out, it starts from one corner and the picture looks like it burns out right before it goes black. That, and the fact that there are a lot of brown outs where I live, enough to fry most electronics. Fortunately the backlight still seems to work so there's hope for it yet. 

I contacted the Samsung reps via live chat and the troubleshooters they gave did not work, and I was told to contact a technician. However, I do not have any official Samsung outlets or technicians where I live, so here's to me trying to Google how to fix it myself. If all else fails, I guess my Xmas gift to myself will be a new TV, and an empty bank account lol. 

That being said, thank you so much once again for your valuable time, especially since you're not affiliated with Samsung. You were a great help, and did an amazing job of breaking it up and explaining things. I hope you're proud of yourself, I sure would be! Hope you have a fantastic week ahead.
