Question about Samsung TXR3079 TV
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?
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).
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.

You need to replace the HOT, FJL6920.

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