Question about Samsung Televison & Video

Open Question

I have a Samsung LED TV that suddenly stopped working. It was connected to a APC power surge protector and the next day it wouldn't power on anymore. I've tried to power it from another outlet and no luck. The led stand by is OFF. The remote control flashes 3 times when I try to use it. When I removed the power cable from the power source to the motherboard the backlight turns on. At this point, I don't know what's defective or what needs to be replaced.   Model #: UN65MU8000FXZA, Version FC04, Serial #: 06G33CCJA01266J   I would really appreciate any help.

Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

If you are having issues with a backlight I would check the lcd inverter first. It is usually 20 dollars on ebay. I would avoid contacting dell as they are no help to people that are out of warranty.

Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

Why did my tv just go to a black screen?


Hello JoAnn Foxworth,

Welcome and thank you for using FixYa!

To answer your questions: I recommend you begin by checking the outlet where the TV is plugged in, or the APC/Surge protector, for power. You can use a hair dryer or lamp for example. If you establish that there is power flowing to the outlet where the TV was plugged in, then the TV will have to have the internal fuses and power supply tested, possibly replaced. If there is no power flowing to the TV, check your fuse box for blown breakers, or bypass the APC/surge protector and plug the TV straight to the wall to test for power.

It is probably a bad battery. They usually don't last much longer than 2-3 years. You could try replacing the battery, but I would suggest just replacing the whole UPS with a new model.

Sounds like a power supply or power outlet problem.
If it's still under warrant, return the unit for repair and get it fixed.
After you get it back do not connect it directly to a power outlet.
You would like to purchase a good surge protector and connect you PC to the surge protector first.
You might have a noisy power lines, and or spikes and surges.
The surge protector will secure your PC Power Supply.
You can purchase one from Amazon.com:

Hope this will give you some ideas.

Does my samsung tv keeping turning itself off because of not having plugged it into a surge protector or is it more a fault with my tv


It is a fault with your power supply module actually inside the tv...take it to a local service center or if its under warranty take it back. surge protectors help prevent issues like this occuring due to damage to the power supply from surges but not having one wont cause these problems unless it has recieved a surge.....in future i would use a surge protector on all your expensive appliances, surges and power fluctuations are very common in mains power i live near the mines and we have power problems all the time!! hope this helps,ben

We had a power outage and the next day all I could get on my TV was the blinking power light. Can you hellp me? I have a Samsung 42" LCD Flat Panel HDTV Model No. LN T4042N edit


Hi, the power surge has destroyed the power supply board that is located inside your lcd cabinet. this board works in conjunction with an inverter board that regulates the raw ac current that is used for many different functions in your set. Normally, this type of damage will be isolated within the power supply but, it could have spread to the main control board as well, depending on how well the surge protector preformed during the surge.

The good news is that, this is a repairable situation. you can replace the power supply circuit board and inverter board as well. these replacements will fix this issue.

please rate and god bless:)

you have to have the power rating rated in amps of the bed...if the rating of your bed and the system are same or even less than that..(i.e. the rating of television is less than that of computer monitor,so u can connect tv for long time than monitor when power goes off ) then u can surely use it.....but it ll provide the supply only till the back up is stored in the battery,when the power goes off
