Question about Samsung TXR3079 TV

4 Answers

Quick question...if there is such a thing

I have a samsung txr3079 tv. when i plug it in i can hear things power up, the red light next to the power button comes on, but the tv will not turn on and there is no sound. does this sound like something that is worth getting checked out or is my tv destined to make its way to the trash?

    yeah my tv shut off on its own and now will not power up sound or picture only the red light blinks on front and according to the site justanswer.com they told me for a $9 charge that it is most likely a capacitor or power supply issue and will likely cost $200-$300 to repair. its only 2.5 years old and i will not buy SAMSUNG again.

    I am also having the same issue where there is no picture or sound, but the red light blinks when I attempt to use the remote.  I too have had it for just over two years.  I was never happy with the picture quality; the black bars on the sides were never straight and the outer thirds of the screen is less than crisp when I playing full-screen high-def channels and movies.  This was the worst purchase I have ever made.  I should have spent the extra couple of hundred dollars to go lcd or plasma, but I cheaped out and I am now paying for it.  If the fuse trick does not work, I will be looking for an electronics recycler in the area since a $300 dollar repair can't be justified on a TV that was $800 over two years ago.

I had the same problem with my Samsung TV Model: TXR3079WHX. I troubleshot my problem with a can of component cooler from Radio Shack and found my problem to be a defective voltage regulator, identified as "QR015" on the main circuit board (the same board that contains the high voltage section).

Caution:

Before I proceed any further I need to strongly warn you. Do not attempt to remove the back cover, troubleshoot, repair or perform the actions that I have done, if you are not a "qualified service technician". Removing the back cover exposes you (and anyone else) to harmful and deadly electric shock, even though the TV may be unplugged from the wall outlet and turned off. You (or anyone else) can be seriously injured or even killed. If you are not qualified, play it safe by allowing others who are qualified repair this for you.

The defective part (overheats and shuts your TV off) is voltage regulator manufactured by Fairchild. The part number is KA75450ZTA. This part is available from Mouser Electronics for less than 20 cents plus shipping. In order to replace this part a qualified technician will need to remove certain cables and unscrew the main board to allow access to desolder and solder the new component.

Hope this helps.

Did you get an answer about whether to pay to get it fixed? I replaced the fuse and it didn't work.

TV won't turn on. Red standby light blinks


Samsung told me this was a common problem and I would have to have it serviced by an authorized repair facility.
My problem ended up being the internal power supply, but they also told me the main boards burn up.

I had the same problem with my Samsung TV Model: TXR3079WHX. However, I was able to repair my set while it was still intermittant (would turn off by itself after 30 minutes of operating, would have to wait 5 minutes before it would turn on again).
